Flex Sensor Glove and Robotic Arm

[@echristle]

ITS ROCK, PAPER, SCISSORS!!!!

[@Lovettfourscore]

No, its scissors rock paper

[@alexanchannel]

No its paper, rock, scissors.

[@haneen3731]

Wow, the way you made the flex sensors is so clever. I like the use of velostat. Great job!

[@RimstarOrg]

Very cool! And it was great meeting you earlier this evening at the maker meetup.

[@WillDonaldson]

Thank you! It was great to meet you too!

[@JeremyCook]

Really neat. I'll have to keep velostat in the back of my mind for future projects!

[@SembeiNorimaki]

The issue with the serial baud is that the bluetooth module transmits by default at a certain baudrate. You can change that by sending AT commands to the bluetooth module.

[@dascaluioan1296]

I think a cool application if the sensors are accurate enough is VR gloves

[@P1_D]

It’s rock paper scissors

[@annitapolyzou8511]

Well done

[@garrett-weil]

Very cool! I'm looking to make a shoulder-down mimicking arm with Arduino, and your videos are a great resource! Thanks!

[@neilshrinath6119]

Although I’m commenting late, one practical application that I can suggest is you can make an accurate hand motion tracking device (or a full body suit!) for CGI-VFX tracking. Check out how to integrate with open source Blender.

[@SippydCreations]

Hi will. Love your videos, really helpful, but what’s the black plastic looking stuff called I can’t understand what your saying in the video

[@WillDonaldson]

Material is called velostat: www.adafruit.com/product/1361?gclid=Cj0KCQjw166aBhDEARIsAMEyZh5cESvl3jP675X6KDmSbky3oY--hQUT_Kh_EAG9bDCithGb0b-oCw8aAqPUEALw_wcB

[@SippydCreations]

@@WillDonaldson thank you so much will really helps

[@1337fraggzb00N]

Use stronger actuators, use steel cable, cover the model with latex and you have a bionic device beyond everything else on the market!

[@himekassa6064]

Hey you never showed us what you did for the arm only the glove

[@DOORNAILS100]

hey Will! Love all (five) of your videos. I'm looking into hobbyist prosthesis myself after getting a new 3D printer. That Velostat is brilliant! I am making a shopping cart with these components, I'll let you know how this goes with my Arduino Lilypad!

[@Banstargue]

How is this project going, 4 years later? Have you improved/upgraded it further? Are you using it to do things around the house remotely? Like turn on/off things or typing?

[@WillDonaldson]

I am not actively working on this project at the moment, but I may revisit it!

[@Banstargue]

@@WillDonaldson Please do! This could be a very, very useful device for people to use!

[@ximeamarilla6928]

Hi!! And what if I do the flex sensor at home?

[@ryanmitchell1729]

IS there any way to minimize the delay between your movement and the hand so it appears to be a 1:1 flush replication of movement?

[@dalexa]

Great project. Is there any way to remove the delay between the glove and the hand?

[@WillDonaldson]

Sorry for the long response, hopefully it answers your question. In short: yes the delay can be removed! The delay can be seen in the first 15 seconds of the video when playing paper, scissors, rock, and around 4:50. The delay occurs because I programmed a minimum threshold before the robotic hand reacts. The main purpose for doing this is is to stop the fingers from jittering as the flex sensors are very sensitive causing continual vibrations. To make these scenes more aesthetically pleasing to watch I programmed a binary reaction (finger open or closed) by adding a minimum threshold before the fingers reacted. As a consequence there is a slight delay in reaction time. An alternative method for reducing this jittering would to be add a filter or signal averaging function to the flex sensor readings (this would also remove the reaction time delay), but I am pretty busy with other work at the moment so I decided just to take the easy way out (in hindsight it wouldn't have really been that hard to add a filter to the program and I probably should've just done it). It might be hard to spot as it happens so quickly but at 5:19 when the fist closes you can briefly see the thumb vibrating/ jittering, this is the effect I wanted to reduce.

[@3mran96D]

Will Donaldson we are thinking to use flex sensors on the fingers, an IMU for the wrist movements on the forearm and we are thinking to use flex sensors on the upper arm (on the elbows and on the shoulder) We are just not sure if it is practical to use flex sensors on the upper arm instead of another IMU, as our mentor recommended the flex sensors for simplicity, we are not convinced with his suggestion. Can you please provide me with feedback on our situation. Best regards

[@3mran96D]

We intend to use 6 DOF robotic arm that mimics our arm movements

[@3mran96D]

With a gripper as an end effector

[@whoawhoa3518]

Your awesome man. hope to be like you soon and learn this stuff. Keep it up. MORE VIDEOS LIKE THIS PLS. Your awesome MORE VIDS LIKE THIS THO

[@OriginalAceXD]

imagine one day when he plays rock apper scissors with it he loses

[@vidheeshapatil4091]

Hi, the robotic fingers appear to have a bit of delayfrom when the sensors are bent. Why is that?

[@andymackellar]

Can you use this tech to make a robotic arm, using one working hand to teach and exercise a paralysed hand.. for stroke survivors etc ?

[@WillDonaldson]

Similar devices are used in the medical field for rehabilitation (and more recently in VR too), however this specific project is definitely only at a hobbyist level. Here is an example of an FDA approved device that uses similar technology to what was demonstrated in my video: kzbin.info/www/bejne/e16TdXlrbauIetE&ab_channel=FlintRehab

[@a.y.p.5088]

Hi Will, do you know if it's possible to measure the exact angle of each bended knuckle with these sensors?

[@SurfGamerz]

Who made this project?

[@filipebrandao5647]

that's amazing..make more videos please!

[@aaliyahnicole9321]

Can you make a tutorial on how you made your board? I'd like your help making and arm of my own

[@WillDonaldson]

I did not make the board myself, it is a device you can purchase already fabricated. www.sparkfun.com/products/13342 Be sure to share a video if you make your own arm!

[@aaliyahnicole9321]

Sure thing👍🏼

[@divyanshbharti7189]

Nice Project ❤️😊

[@pigeonbass11]

Hi! I have an Arduino Uno but the SMD edition (doesnt come with that shield you removed) and also an Arduino Mega 2560. In terms of programming, what would I need to do different since my board is a different model than the one you used in the video? Thanks!

[@gamerzwaltz9951]

List of components and what type of Arduino was that.

[@TheSreedevi66]

where we can get vleostat in our home

[@Gallardo6669]

Awesome

[@corral538]

Calibration program inside the Lilypad and servo program inside the Arduino?

[@sarwadharmamahalaxmigroups7637]

How to order please

[@GodFlame326]

Hi Will, nice work bro! Can you ask em a simple a naive question? For the very same project I´m using an Arduino Nano and a Uno, can i connect both between a bluetooth module like you tried in the video (I know you weren´t sucessfull because of the lillypad) and pass the information trough the controllers without losing any kind of movement? I´ve been thinking on using Xbees shields but it´s too expensive for this project. Thx, would help a lot if i get any answers!

[@aaliyahnicole9321]

Did you ever fix the speed?

[@Music-lv8xf]

how can I make it if I want to record or store the one combination of flex to another combination. Example from thumbs up to pointing using index finger? did you get my point?? it was like from point a to point b? how am i supposed to do that??

[@SembeiNorimaki]

store the readings into arrays, then to replicate them just read the array and move the servos accordingly

[@13.aftaburuz3]

Can we use the arduino boar uno r3

[@soheibbel5085]

That's so cool bro

[@donovantrevillato4869]

You rock!!! You"re gennious!! so much thank you

[@patrickybr]

Hey nice project. Why did you not used the bluetooth hc-05 do you know how to do the program to use it?

[@nkumar3085]

Love you guy....tq you coding 😍😘😘

[@Guds777]

Next, velostat bodysuit. And exosuit. Dude you are on your way...

[@nikcile4034]

How did you not see the applications in vr for this?

[@WillDonaldson]

There are definitely ways this could be adapted and improved. I encourage you to work on projects like this yourself and share them (as a personal preference I am more interested in robotic arms than VR). Here is a video on one of the leading VR gloves: kzbin.info/www/bejne/hXyVqmeQaq6ekJI&ab_channel=SmarterEveryDay

[@dreamzz90]

www.ncbi.nlm.nih.gov/pmc/articles/PMC6766835/ have a look at this application! Researchers from Taiwan and Nvidia working on gesture recognition using the same smart glove!

[@abhishekkatti7982]

how did you establish a connection between two HC05?? really urgent..

[@SembeiNorimaki]

you need one as a master and configure it to pair with the slave using AT commands. You can find detailed explanation of how to do it by googling "Pair two hc05 modules"

[@murt7923]

What is bluethooth module

[@redsharp2]

DUDE YOU COULD CREATE CHEAP VR GLOVES USING THIS METHOD PLEASE LOOK INTO THIS

[@rafaelgiorgana3442]

How did you make the sensors ? I bought the velostat but is too unstable

[@yosefhassan7873]

i've been looking for velostat for quite a while, do you have any idea where can i buy it from ?

[@rahulmawar1614]
