[@crazylegs85]

This is exactly what I'm after. It's weird because the davinci surgical assistant has been around for at least 20 years, and I'm really surprised that no one in the DIY community has come up with a variant for the component repair field. At least one for just the fun of it

That is a great idea, even just to have it as a dynamic 3rd pair of hands would be helpful.

[@potatomeatlabs]

I'm a software engineer and actually developed software to control an autonomous surgical robot (which mostly did suturing, anastomoses, etc.). We had some preclinical success on pigs, but eventually the team went our separate ways. One person actually joined Intuitive. As part of my design process, I was actually able to sit in and watch a minimally invasive surgery which used the daVinci robot, and use the robot myself to suture up some silicone training pads. It's surprisingly 'intuitive'... even for non-trained surgeons like myself. However, our platform we developed used completely custom tooling, and a 6-DOF arm from KUKA, along with a bunch of expensive fancy cameras. Anyway, it's cool to see other people working on similar projects in a personal capacity. It's a neat field and challenging problem, especially when you throw in robotic autonomy.

[@tomgidden]

I used a daVinci S at a Science Fair with my nephew in San Diego, and it was so much fun. As I've always relatively unsteady hands, I was surprised that it completely smoothed out any tremors, and I was immediately doing fancy two-handed moves with it, stretching rubber bands over things. The surgeon working the stall noticed and mentioned I was surprisingly dextrous with it. Since then I've always wished systems like that were available for non-medical hobbyist uses, like precision electronics, model-making and so on; cut-down, non-safety-critical versions of course.

[@guiwood]

Certified Da Vinci robotic surgeon here. A few comments: - Yes, it is awesome to use one. Not only the range of motion and precision, but also the 3d high definition vision inside of a patient. - the instruments you were able to get are from the Da Vinci Si. This version is deprecated and if I am not mistaken, they are not being produced anymore. The new version (Xi) uses instruments that work similarly, but are not compatible (planned obsolescence for sure, the Xi offers very few benefits over the Si, which was already very good, they lost some of their patents). - you control the instruments with two joysticks. There are pedals that you use when you want to change to another arm and control another instrument, or when you want to control the camera. In your device you may be able to control rotation and opening and closing of the instrument. What is still missing in your device is advancing and retracting, and hovering your instrument. The Da Vinci relies on a "remote center" in the trocar. Therefore, it won't damage the patient's belly when moving. Overall, great work! Feel free to DM me if you need some help!

[@guiwood]

One more thing: there is little to none haptic feedback. If you pinch the joystick too hard, you will damage something as the robotic arms are very strong. Honestly, you get used to it and you rely on what your seeing only, which is of very high definition.

Believe it or not they had a demonstration set up in a hospital I was at once. They let regular people operate it and it was super intuitive. The input had a view finder that showed the two sets of claws you were manipulating. Each hand had two finger loops mounted on armatures that let you operate the grabbers. The coolest part is that everything had a slight force feedback system so you could feel how you were interacting with the objects they set up(coins, sponge, etc). something about the size of a penny felt like the size of a dinner plate through the system.

[@barcodenosebleed5485]

Penny-dinner plate--that is awesome. Like they're impedance matching the feedback to a scale our bodies are more adept at handling. I'm just in awe thinking about how much nuance you could pick up on like that. Super subtle differences in how various tissue might feel that might just barely be discernable to gloved fingertips. I'm wondering how immediate that feedback is, like could you sorta glide along a ridge/seam just by feel alone? I suppose that particular kind of motion doesn't make much sense in a laparoscopic setting where you have a pivot at the keyhole. Anyway, very cool.

[@bears7777777]

The company I work for designed and built a robot cell that loaded baskets of medical tools/devices into a series of sterilization machines. Within several months, the baskets that the robot used to load the parts had become corroded/worn to the point of replacement. These aren't delicate mechanical devices mind you, these are heavy-duty stainless steel baskets that would knock you out if someone threw one at you. I can understand how these only have a few sterilization cycles before needing to be replaced.

[@channingchriss2091]

I used to work with these every day, but it was 8-10 years ago so it was pre XI, I believe it was SI. The motorized discs would "home" themselves after an instrument was inserted, and a successful homing had to be performed before the instrument could be extended into the patient. It was a multi stage process that allowed the robot to ensure that all the cables within the instrument were intact before they came into direct contact with the patient, and to allow the robot to sync the cables between the two independent sets. There was some kind of force detection within the main unit that would detect irregularities, so if the instrument was misaligned and attempting to move in an unexpected way while restricted inside the cannula, it would report an error. A red light would show on the docking portion of the arm, the assistant would be unable to advance the instrument into the patient, and the surgeon would not be able to control it. Major pain in the ass to use but a lot of really cool technology packed in

[@spartan5280]

I have been working on this exact same project for a few years. Decided to swap to stepper motors due to the coupled motion compensation using up a large portion of the movement range on the servos. The actual robot is cable driven all the way to the mounting plate. So, all the motors are in the base of the arm, which helps with balancing the weight. Also, due to the arm being a remote center mechanism it only requires two motors for the bulk of the motion. Also for control I was thinking that a magicleap/ultraleap hand tracking unit would be the most cost effective way to get 6dof control for two arms thought it would not have force feedback which is somthing the real robot has. I was even looking into the idea of the robot being controlled over a network connection so the robot could be controlled remotely.

[@tylerwillging8074]

Yes I was thinking stepper motors as well, because the Servos typically only have 180 degrees of motion but most of the pucks can travel further. Also, probably easier to implement torque detection with stepper motors.

[@Therandomlaugh66]

Hey Bennett! I’m actually used to be a Manufacturing Engineer for the Core Instruments division of Intuitive! You’ve got the older Si instruments there. Very impressed with your work! There’s a lot that goes into making that “talking” between the robot and instrument happen but you covered the basics great! A little background on the “life count” they actually have to qualify every instrument for a specific number of lives by running new versions through simulated use and do some math to calculate what the max life count would be. All has to be submitted through the FDA and approved for every country we send instruments to! Great Video!!

[@piro247]

When I was a kid, the natural science museum in my town opened a large addition. They had a week-long special event to promote it. One of the things they arranged was for an entire da Vinci training set up to be temporarily on display for people to try. They had a computer-based simulator, but also a real robot too! They had a bunch of challenges for people to try like wrapping dental rubber bands around various small objects. It was super cool to learn about the technology, but then actually sitting at one for a few supervised minutes to see how much skill goes into making and using those units left a lasting impression. 11/10 day at the museum.

Absolutely not a "rediculous endeavor". This is Absolutely brilliant and I hope more young people are inspired by your curiosity and determination. You are literally showing everyone how anything is possible.

[@channingchriss2091]

On the topic of instrument control, only two instruments are ever under direct control by the surgeon. There's a foot pedal that switches the active instrument with whatever instrument is located on the same side as the pedal, and it's placed in a locked position. This is usually used for retraction or switching between needle drivers and scissors when suturing. The camera is also controlled independently (I can't remember if this is foot pedal or hand switch controlled) but disables all other inputs while the camera is moving. Usually the camera is placed as optimally as possible and moved as little as possible, both to prevent disorientation and to keep instruments in view at all times.

[@parkerjk11]

Worked in the OR a bit as a rotating surgery medical student. They have the camera/endoscope attached to one of the arms and they toggle between different tool arms like the input on your TV. Once u set the camera arm’s position, you change inputs to a different tool arm, thereby locking it in place. If u could program an Xbox or PS4 controller to control the arms and use a button to switch inputs that would be able to mimic the da Vinci machine quite nicely!

I might suggest looking into how 3d mice establish their many degrees of freedom.

Using an microcontroller you can measure the changes to twist, pitch, and height.

[@robomaster1000]

I had the opportunity to use one when the local hospital, that my parents worked at, got one and had a demo in its loby. It was extremely intuitive and required no leaning curve. I was in highschool at the time and it was really fun.

[@robomaster1000]

I will say that the freedom of movement afforded by the complex system was limitless. I had full range of motion of my hand. And there was a foot pedal that allowed you to pause movement of the system and pan your hand away. Similar to picking up a computer mouse off its pad moving it over and bringing it back down. After a couple minutes I felt entirely one with the machine

Hi Bennett. Excellent work. I started down this same path last summer, prototyping a possible exhibit for a California science museum. In the end the exhibit got dropped ... but I'm still very much interested. I've got 3 of the "blue" units here (pincer-type, can't recall exact one) and a similar box of iterative 3D printed mounts. I like your spring-loaded coupling mechanism. Mine simply rides down the grooves and snaps into place, depending on rotating the discs until they seat properly. I'll check out your git repo.

It wouldn't give the haptic feedback, but a Leap Motion / Ultraleap Hand Tracker may work to an extent. For hand tracking *and* haptic feedback, short of making a OS Version of the Proper Device (which would be cool af, but agreeably hard (although a robotic arm without motors, if that makes any sense, may work. James Bruton did an OS "puppeteering rig" for the terminator torso+head, so between that and the OS Robotic Arms out there it *may* be doable with existing work and some integration hell)), there is an Open Source "Haptic Glove" type thing. I am unsure on latency and all that, but it was basically gloves, cables, and a sensor and/or motor module. They also have a discord which would be great for troubleshooting / brainstorming.

Hey, like several other commenters, I am a software engineer and I had the opportunity to use the Intuitive Surgical daVinci during CVPR conference. I must admit that the most important element of this experience was the intuitive control of the robot using „pinching” and foot-controlled pedals. Equally important was the control stand itself, equipped with goggles and head and elbow supports. I am not sure if the goggles had stereovision. I had the opportunity to perform treatment on physical rubber rings as well as virtual training programs such as „moving a ring along a curved wire”.

[@ER-vy1yl]

There is stereovision for the operator but not the assistants.

[@kyleballing]

I worked at Intuitive for 5 years as an engineer trying to figuring out how to manufacture these surgical tools. I assure you that limiting the number of uses is purely a safety factor. It is critical that they don't fail mechanically and some surgery really pushes them to their mechanical limits.

[@cashel1111]

that fact that you have made it this far is impressive as!! working out those 4 axis ones is going to absolutely suck also as far as input is concerned, even if you built a mechanical replica the interface between that and your instruments is going to be some crazy complicated maths if you get this working to even a basic working state i think it would be incredibly useful for things outside the medical field, especially since you have worked out there will be a steady supply of the instruments. things like small scale electronics come to mind. I also think if you find the right instrument, that modifying the end effectors to suit other purposes would be another avenue for investigation. instant new follower here, lets see how much patience/endurance you have for this task!

Very cool! (Love your soldering iron "drill press". 😄) About a decade ago, Intuitive brought one of their machines to a computing show I was at (can't remember which), and and they let people try it out moving little dice around. It was really amazing how they made it all feel completely natural. I also worked at a company that shared space with a machine shop that made the scissor heads, so saw a ton of them coming off the CNC machines and on the assembly benches.

The controls at the station are electronically counter balanced and have different selectable scaling options built into the software to scale down you hand motions within the work space.

Could also install rotary encoders on the balance pulleys to translate the movements.

[@williambunting803]

This is an awesome project with a very real customer base. There are people who live remotely and there is a need for some kinds of minor surgeries to be performed on site. In my case I live on a boat and alone. The kinds of procedures are initially observation, recording, and transmitting information for remote diagnosis. The second procedure set is to do with a large number of skin surface procedures treating infections, cleaning and closing wounds, removing foreign objects such as splinters, glass fragments, and shrapnel of various types. A robot to perform this kind of procedure does not need to be a long reach robot as in the video. It will best be a very local kind of device that is placed on the body, or the body is pushed against a device that is fixed to a structure. I would suggest starting with a cylindrical housing of around 200mm inside of which the process takes place. There would be a rotary housing which carry perhaps 3 short “fingers” that carry tools and a number of auxiliary functions such as suction, flushing, wiping, injecting, etc. Note the penetration reach of all of these devices is very short or shallow. A typical “procedure” might be to lance an infection, clean, disinfect, close and apply a dressing. Regardless of whether you see this as I do, you have me thinking about this need in a practical way. I am going to follow where you go with this with great interest. Thanks. I am a customer of a self surgery aid.

[@ceored]

I worked in surgical robotics for a few years, the way the tool attaches is via the sterile drape, you have it right that is it is spring loaded but each input axis typically has a disc that that can side before engaging and creates an oldham coupler to take up small misalignments. Typically you have to engage the drape side first onto the robot and then the drape to the tool. As someone else said the robot uses an RCM- remote center so the Dofs needed are smaller than you might believe- this reason the DaVinci has so many joints is to setup the RCM to the patient and then have redundant motion for clearance arm to arm. The Xi is far superior to the Si in this regard. As to the inputs, you really don’t need anything crazy. The reason the DaVinci inputs are crazy is that they need the user to match the location and orientation of the tool. You can get away with nearly any kind of 6Dof sensor and it will work fine, you just have to pay attention when you clutch in and out a lot more.

[@ceored]

The tools are cool inside, there are many different mechanisms to drive the wrist depending on device. If you open one know that the cables are tungsten and will be near impossible to cut and once cut conventionally become unusable.

This content is absolute gold. I am subbed and glued to my seat, both ironically and unironically. I have been waiting for someone to tackle controlling these, as the used tooling looks very capable for other uses outside a surgeon's use.

[@Chriss120]

WoW. This is the first video I got recommended from your channel and I must say, this is some great progress.

[@Bigyellowcube]

From under 100 subs to more than a 1000 in one day! And judging by the immense quality of these videos, it's only up from here

[@ogland6482]

My dad worked on the user interface for intuitive surgical. I think the best thing is to have something that takes in hand movements ie the pinching rotating and back and forth motion of someone's hand.

[@NateTheMeh]

God the variety of shots In this video takes the production quality up like 10 levels. What an AMAZING video and channel.

[@Tamperkele]

I think a diy robot would work just fine in our clinic. Maybe the doctor will finally get me a raise.

[@romainboutet8364]

Gosh your montage is refreshing ! I really enjoy your effort on this, and on the content also Hope your channel gets the success you deserve ! 🚀

[@AaronCederberg]

This is wildly unnecessary, but I’m so incredibly glad it exists. Thank you, sir. Keep it up.

[@lesto12321]

cool! I used the controller of this in a conference, they had this hand controller but so small it would sit on a normal desk, and was connected to a PC running the simulated machine; the output was on screen BUT also on the 2 lenses microscope, so you would get full 3D. I saw many people struggle with it, but i aced their little "obstacle course", it felt very intuitive. I remeber I could move my hand whenever i wanted and never hit any physical limit, so there is some VERY smart mechanical design there

[@UneducatedEngineer444]

This is really neat. I build non invasive medical devices at work. I don't have a college degree but I am determined to improve one of our products before I die. Videos like this are very inspiring to me.

[@JeremyChung]

THAT INTRO SLAPPED. Earned a sun after only 2:40

[@nigelsilva7719]

I actually got a chance to play around with one of these when I was 8 or 9. I was really interested in the body and wanted to be a surgeon so my mom took me to a davinci surgical system information conference (geared more towards elderly people who needed surgery) and they had one on display that they would let people use. It was absolutely incredible, especially for the time.

[@StorySpotlightDaily]

I can see your focusing and studying other KZbinrs to make these videos as good as they can be, as soon as possible. Paying off really well, good camera presence, editing etc :)

[@oOWaschBaerOo]

the way the connection could work ( i dont know what is in those discs ), magnetic coupling, once the device is close, the shaft and other half of the coupling magnetically attatches ( or, the shaft gets pushed out by a mechanism when its fully inserted )

[@Nelson-q3y]

fantastic. A while ago I also studied this equipment with the idea of making a prototype but I never reached as much as you. Keep going.

[@zbaktube]

About the controls: 1, a glove that controls the 2 metallic "fingers" precisely. 2, Either 2 cameras to detect your hand "gestures" (we do not care the fingers) or a leap motion to detect the gestures. 3, some kind of virtual UI to assign the robot arms to your arms so you can control them with 1, and 2, This is a good starting point. Later on you will need some kind of stand as your hands would be super tired and painful after keeping them in air for 30 minutes. If you like it and you need help, just let me know.

[@chrischris1722]

For the control I would recommend off the shelf gimbals, starting from those you should be able to move them and read the change in position of the individual motors. Hilarious stuff dude.

[@Vysair]

This guy is starting to resemble a mad scientist. Like an actual technical prowess with the "polishness" of his creation to make it feasible

[@edupuertasfruns]

So dope, I am following your endeavor now

[@TheKunalsan]

This is so dope! Ive been trying to diy one of those 3Dsystems touch haptic controllers, as a "baby" step to try and do something like this. Cant wait to see where this goes!

[@michaelrogers6008]

Okay this is kinda crazy because I have actually had dreams about making a robot with these. Bro. You are in my head and that is so coooool

[@makermandan]

Dude, this is sick! Figuring out how to control the arm looked like a nightmare because of how convolved the inputs are.

[@BennettStirton]

Thank you! I’ve certainly got my work cut out for me but I think there might be some shortcuts 🤞

[@imaginationfactor]

For control interfaces. They look like those DJI osimo camera gambles… maybe you could use one of those as a test input? It almost looks like two of those together, might give you the 6 axis…

[@SlighltyArsenic]

For input you could probably use a switch joycon lol, 3-axis gyro, a trigger and few buttons. You could also use both in conjunction for even more options.

[@fuge314]

I bet that looking into puppeteering solutions could help a lot in developing controls for the system. They seem to find some amazing engineering solutions for precise movement on a shoe string budget.

[@gimmeabreak6022]

bro this is really cool hope you blow up!!! also since you mentioned that there will be way too many axises you could imitate your robot in solidworks and calculate the degrees of rotation from that (if thats possible) since solid works allows you to not allow your parts to collide into eachother
