This time on 3DprintedLife, I build a ridiculously powerful robot arm. Capable of lifting 5lbs at full extension. But I didn't build a full arm, just most of it. 5 Axes to be exact, with the 6th coming soon! Then I strap on my phone and film some stuff using the robot. This video has it all; 3D printing, harmonic drives, custom electronics, breaking stuff, fixing stuff, and breaking it again.
If you'd like to build this project yourself, you can find the files here. (I would highly recommend waiting for the re-design unless you know what you're doing)

@yourt00bz Жыл бұрын

Forgive my huge ignorance is the accuracy in motion control derived from a detailed high fidelity inverse kinematic model or from the underlying type of drive and power distribution control system? or are we sufficiently advanced in software and hardware interfaces that the underlying mechanism is almost irrelevant because our computation and memory ram prices are so cheap that it doesn’t matter ?

@aleksjenner677 Жыл бұрын

@@yourt00bz Seems you don't really know what you're talking about, Bub. Software has no effect on accuracy, motion control has been used for filmmaking since the first star wars movies in the 70's. As long as a motor knows where it is, and can return to a set position then it'll work. Only thing that will ruin accuracy is mechanical slop in the system.

I only saw this reply half an hour after you made it. I know what motion control is. I don’t know much about software except that it costs a lot and I don’t need to know anything about filmmaking to understand the bespoke engineering ILM did to enable motion control to enable accurate motion matching for manual analogue in-camera matte compositing myst have cost a fortune. Whereas OP of video using his own genius,as per your suggestion, might have his own solution as opposed to proprietary niche industry offerings which are expensive. And again, as per my comment, no. I don’t know anything about this stuff or what I am talking about, apart from old electrical cybernetics and that’s why I’m asking questions. You should learn reading comprehension before jumping to be rude as reply to your own misunderstanding , instead of a follow up question in admiration to your comment. I for instance have a fair idea how much motion control rigs costs from Even the cheaper Shenzhen enabled startups targeting smaller film studios. Hence the preceding “forgive my ignorance” and then the question. I can’t repeat this enough, please learn some manners and some social skills, it will aid you in life?

@TD-er Жыл бұрын

Just wondering, why don't you use a "mechanical" input first? Thus make a very simple clone with the same ratio for distances between hinges and then simply add a potentiometer on each hinge. Then you only need to 'copy' the angles on those hinges first to your motors. If you get this communication smooth, you know any computed intermediate step will also work on your arm too. This will also help you find any issues where each hinge may struggle to keep up with rotational speeds on the input. As a bonus, you can also log a few basic movements you can make by hand so you can then try to experiment on the needed resolution for how many intermediate steps are needed and whether this may depend on the angle and weight of the moving hinge. It may also make it a lot easier for you to try movements from point A to B where you can easily see up front what would be a better bend shape of the arm. For example I can imagine it may appear more smooth when the movement from point A to point B isn't a straight line, when for example some hinge may need to lift considerably more weight and needs to accelerate beyond what it can handle, when moving in a straight line.

Im struggling with much of the same, I love stepper motors, but when it comes to torque and smoothness when handling mass, servo motors are having value. You can get a driver that handles electrical wave construction, like ie. sinusoidal or trapezoid and off course the accuracy of an encoder for feedback. Holding torque can ie. be simulated via the encoder, just pushing the other way if the error rate between expected position and actual position starts to drift. In addition and even though it’s more expensive, current (A) will help with torque. Anyway, love your project!

Most of the cost of high-tech things isn't the materials. It is the countless hours of tinkering done in a back room somewhere to get it to work. And then twice that amount of time again designing the tools to mass produce it in one tenth the time and guaranteeing that the mass produced ones still work as well as the prototype.

@centurialinc Жыл бұрын

I would try closed loop stepper motors. I use them on my cnc mill and lathe and they work well. It's also a simple system. The stepper drive gets the command and simply confirms that it made it to that position. You choose the amount of error in the software and specify how much the drive needs to try to reach or hold position. If you buy those it will likely change the size of the robot as the motors come with the encoders attached and it will definitely increase costs. But it would speed up the completion of the project. The software is the main issue with these types of cnc machines. I would focus primarily on that. The AR3 robot project by Chris Annin is very well documented and lots of software examples and tutorials are available you should check them out if you haven't already. Good work keep it up and I'll be following along.

All I can say though - as much as matrix math sucks, the equations really help in terms of actually getting smoother performance. The trick is to just define the initial configuration (when everything is at zero) and define your joints (which will take a while for sure). After that, program in the transformation equations like Power of Exponentials and let the computer do all the hard work The best thing humans ever did was tricking rocks into doing math for us lol

@tylouww.1915 Жыл бұрын

very nice, but the problem is you can only reach 5 degrees of Freedom and not all 6, because you have only have 5 joints. You need another twisting joint between your current joint 3 and 4 to be able to reach every position. So the first 3 joints are for translation (xyz positioning) and the joints 4 to 6 are for the orientation of the endeffector. The simplest way to design it, is to model the joints 4,5,6 in a way that their rotation axis meet in one point. That point is then also the point that is translated in space by the first 3 axis. You can search online for like "robot with spherical wrist" for more information. Also a good open source control software is from Chris Annin, he has a yt channel with robots and how to control them :D
