[@zephyrisrecording3653]

Idk why i'm typing this out but here is an explanation of some of the stuff in the video The Motor : So Basically what he has in his hand was a motor and sometype of computer/controller on its own the motor can be powered to spin one way or the other combining the two lets the motor be controlled more accurately with the computer the computer will take code that he wrote to give the motor instructions. Controlling the head : Michael first controls it with his mouse what he did was make the computer think of the motors on the side as X and Y like a chart so he can move it anywhere in a 2d square and then he simply just made it read where his mouse is and tells the motors to go to that specific place in real time. (Side note remember the bit when the motor was going back and forth in a line really slowly basically that lets the computer record the amount of space it can move in and Michael programs it so when it uses too much force like when it hits the edge as a stopping point Up and down : Basically just adding another position to move in so we have X and Y he just gives it Z and uses the Leapmotion tracker which can track how far or close his hand is to the sensor and gives the motors instructions to go up and down The Code : Dynamics Bounds detection i already somewhat explained this in how he controls it in the 2nd part but lemme just say it here again basically the portion where the motor was moving back and forth, there you see the motor and computer working together to map out the amount of distance the motor can move hence fourth Bounds detection like he said the code just gives instruction to the motor where when the motor needs to use alot of force or power than it normally does it will stop the motor which sets a bound. Conclusion: Man i am dumb i've watched this video before but forgot that michael already explained most of the code and i basically rehashed this welp im still just gonna comment this and hope this gives a little bit more of a better explanation which i don't think i can beat michael he is amazing and explains it way better.

I've seen reaction channels that take Michael too seriously. I've also seen some that treat everything he says as a joke. Chicago Reacts has managed to be the middle section of the Venn Diagram of reacting to Reeves, Kit laughs whenever Michael makes a joke, but he also tries to understand what Michael is talking about and actually supports his ideas. They even watch the ads and genuinely seem like they might purchase the item or at the very least check it out. For these reasons, you've earned my subscription

[@DEATHBYFIRE09]

I don't know EXACTLY what he's doing here, but the idea is he's taking a regular motor - that will just spin for as long as you tell it to - into a servo motor - one that will also spin for as long as you tell it, but can tell exactly how many times and how far its rotated in that period. So he can use that new servo motor to accurately travel along the rail to the position he wants it to, just using the motor itself as the sensor. Otherwise, he'd need a complicated array of sensors to tell exactly where the motor is on the rail, and when to stop it running, the servo motor can be told "Rotate 30 times plus 270 degrees" and it'll do it on its own. You just need some code to convert distance into "Revolutions" for the servo to understand.

[@mr_darkrainbow]

The ODrive device is an open source platform that allows someone to combine a relatively cheap electric motor with an also relatively cheap rotary encoder (a device that translates rotation into electrical signals which can be counted and so on), this allows a user to control the motors exact position of rotation, instead of just speed and direction (this is what servo motors, and also stepper motors do) all while being a whole lot cheaper than commercial servo motors of the same power / speed, and much faster and more powerful than other solutions at a similar price. Each ODrive module can power and control 2 motors and users can communicate with the ODrive through various interfaces, as well as connect more ODrives to one another. TL;DR The ODrive provides a powerful motion control solution comparable to high end commercial equipment, while being generally cheaper and open source.

The light of hope in his eyes slowly dissipates as the video goes on hahahaahha but he's like a proud dad although out so it's so funny and cute hahaahah

[@Necrobadger]

It has been years since I did anything with coding, but the piece of code he shows at 6:15 is to set the homepoint of the surgery arm, as well as the area which it can move in, both of which are described by an X, Y, and Z axis to make a 3D area in space. I'm 100% sure there is WAYYYYY more code involved in the end product.

[@F3ARaG3]

That circuit board is a raspberry pi (basically a mini computer that can do almost anything you want it to via code) or the brain connected to all the motors and it takes the inputs of the controller to tell each motor what to do. The code he showed was the logic that the raspberry pi needed to run those motors the way he wanted. So the code also made a grid that mirrors the robots range with the frame of the motion capture camera so that it can take the values of the hand on the motion capture cam and move the CUM to those same coordinates in the range of the robot.

[@88Spint]

OMFG your face when he brought out the knife hahahhahahahha!!!

[@Muskar2]

6:07 It's basically just instructions and they're generally run chronologically, the same way you read them. And what's shown on the screen right there is the part he has called "calibration", with a function called "calibrate axis". The code shown is incomplete and not very well organized so it's hard to be sure, but it looks to me like it's code run for each separate motor, pushing it to each edge until it uses amperage beyond a certain treshold, and then returning to starting position, like he explained afterwards.

[@LiHam-34677]

I think you should watch Michael Reeves headhunting drone swarm video. It shows the kind of person he really is

[@matildalyssa]

i do always anticipate his next video but i am also at the same very scared of what he will do

[@grantbell8143]

Coding provides instructions to the motors on where and when to move. For example, when Michael was moving his computer mouse around, and the motors were responding accordingly, there was some sort of code written instructing the motors to move slightly right when the mouse has been moved slightly right. In other words, coding gives the motors a “brain”

[@akaruianims]

I'm no master in python(the code language Micheal used in the video) by the looks of it, he wrote code to send instructions to the motors to basically copy whatever movement he makes with the mouse and later on with his hand.

[@Leviathan3DPrinting]

Odrive is a great idea... I’d love to see support between the odrive and other controllers like say a duet or something. It’s designed for position and speed control of brushless motors.

[@diymotionsimulator3744]

Servo motors are commonly used on 3D printers because they provide very high precision based on the resolution of the encoder attached to the servo. Encoders provide digital waveform that returns the number of turns the the servo has performed. They use limit switches to register the end point of the movement across the extruded aluminum "basically it learns the stop points when it reaches it's end point on the extrusion the number of turns to the end points" . Servos are many times used on actuators because it has high procession as much as 30,000 points per inch. The other way without end switches it just checks the time the waveform has not changed and then stops the servo it would learn the end points but 3D printers put limit switches because it provides a more accurate end point.

[@iqchank2106]

To explain the coding montage real quick basically the motor will just keep going in whatever direction you tell it to and the more it has to push through to keep spinning the more voltage it uses. The motor he's using allows him to read the voltage being supplied to it at any given time. When it's on the rail the voltage required to move it is fairly consistent but once it reaches the end it can't get past the barrier so it pushes harder which means it's using more voltage. The program is reading the voltage of the motor and once it detects a voltage past the limit he set it knows it's reached a boundary and is told to stop.

[@cluegames6890]

[@gh05tparkourfreerunning31]

I'm a programmer and here's an explanation of the code: It's code. It tells the computer what to do. You're welcome

[@kub_luk2069]

A little late, but hey - better now than never. His code is basically comparing the voltage each motor uses to determine it's position. When the motor hits the end of a railing, it starts using a lot of power because it is trying to go somewhere it can't. The code detects that and knows that the motor is on the end of the rail. Now it can compare the edge values to the distance traveled of the motors to get a XY coordinate. It's similar to grabbing a pencil and drawing from the bottom left corner of a paper to basically anywhere on the paper. You can see the end of the line - that's his coordinate. I hope my explanation in understandable :D

[@kylecueto]

Probably a little but late for this explanation but as a mechanical engineering major that wants to go into robotics, I want to help people understand. The motor that Michael has in the video will only turn as long as it gets power and will only turn in one direction as in CW or CCW depending on which part is attached to the positive terminal of a circuit. By adding a controller, he turns it into a servo motor which is a motor that has built in controller board that is designed to communicate with a microcontroller (mini-computer) in order to give more precise movements in increments of rotation. By turning it into a servo motor, he can control how fast or slow the motor rotates as well as the direction it rotates. The code that he wrote is how the motor is allowed to talk to the microcontroller that it is hooked up to. As for the dynamic bounds detection that he mentioned, it basically works like this. When operating any type of electronic, it will always use up some amount of wattage and voltage. The amount of watts that it is pulling is determined by how hard the motor has to work. The microcontroller can be coded to read the voltage or wattage rating that the motor is giving off at any given point. So it reads where it has to go in relation to where it is at that given time in accordance to the positional input that he wrote in with the VR camera. When the motor suddenly has to use more power or voltage than what is deemed as normal operating volts or watts, then it know it is at the end of the bounds of the machine. This is what I mentioned previously as that the motor pulls more voltage or wattage (how ever you want to measure it), the harder that it has to work. To put this into more of a visual aspect, let's say the operating voltage is 5V for example. The second that it gets to the edge, it is pulling 5.1V. This is higher than the operating voltage so the motor knows at this point that it has hit the bounds of the machine.

[@fruittree1670]

A servo is a very accurate motor that’s very strong. It can go to the exact position it’s told to and can switch directions really quickly. A regular motor has less general strength, but lots of torque, and it’s a lot less accurate

[@PatrikTheDev]

Simple explanation: motor goes wroom wroom real fast pretty accurately More extensive explanation: these are motors used to power RC cars and airplanes, but they have been modified to have a digital encoder which allows the computer to track the movement with a high accuracy. Some software on the computer then controls the motors in a way that they keep their position (provided by ODrive themselves)

[@duncancameron1377]

A brushless motor: Basically a motor that doesn't use brushes to switch the electromagnetics polarity (which is what causes the motor to spin depending on the voltage supplied controls the speed since the electromagnetics are stronger with a higher current supplied) , instead most brushless motors use three-phase power which is three seperate AC power sin waves shifted an equal 120 degree from each other. Not the best explanation but I'm pretty sure that's the gist of it. For a more in-depth explanation look up how a Tesla model S works or any other brushless motor vehicle.
