It's a useless device, the motors/manipulators take up too much space and the patterns on the ball and gears (if made with steel) would require extremely cost prohibitive machining. Some kids in college made it to flex their intellect but its actual applications in the real world are 0. Otherwise they wouldn't be showing how this unpatented device works in such great detail.

This is one of those things that just makes so much sense that you can't believe no one thought of it sooner. It is pure genius.

Bro this is the best mechanical animation I ever did see on KZread! I must find out how to do this kind of stuff.

It's like the ball is threaded in the way a multi-directional screw would be threaded (it can engage or disengage clockwise or counter-clockwise, depending on pressure... generally impractical for screws) and then the driving ball joints are the single-direction threaded guide, but turnable so it can engage to turn the multi-directional threading on the ball. Very neat!

@@cirogarcia8958 I agree with you completely. I work for a company designing and testing precision motion control systems, and while it would be possible, and not too difficult to use motors with built in rotary encoders, the lack of encoder wires coming from the motors show these are running in open-loop with no position feedback. If you had motors with encoders and pair each set of motors on an arm in standard XY configuration(the 2 motors would be offset 90°), then you could do the trig calculations to calculation the physical travel/rotation of the ball. Then interesting part comes on how you want to handle the second set of motors on the other arm. You could either do the pain in the ass over, complicated route, of having all 4 axis running in sync to handle each command if your software will allow it(I've done it on hexapod systems, and it is a lot of math and an absolute pain), or assign roles for specific axis. I'd probably have one arm handle the XY rotation, have one of the motors on the other arm handle the Z rotation(the X and Y will need to be set to slaves axis of Z to rotate when it does, while still following their own commands). The 4th motor on the arm with the Z axis, I would have running constant low current to always be opposing a primary axis to prevent the backlash issue seen at 4:35(the jerking at the start of the movement is the driving motor is shifting the contacting fact of the ball's gear). While this is a cool concept, the backlash issue inherent to this design rules this out for any precision work, and the low contact area because of the possible tooth width means that with any load added, you'll see wear become a more serious issue. With wear, you will increase your already existing backlash issue, and at worse, break a tooth or one of the rollers on the motors. This will not reliably be able to handle loads, and if a tooth or roller face breaks or shears off, the load attached will come crashing down. Also the fact there is no simple way to add electrical limits to a system like this, means that any programming mistakes with this will likely result in damages. TL;DR: Yes to you, and sadly no to the design... it is cool though.

@@MinatoAsk "You could either do the pain in the ass over, complicated route, of having all 4 axis running in sync to handle each command if your software will allow it(I've done it on hexapod systems, and it is a lot of math and an absolute pain)," I was actually referring to IK there as it's the only way to run a hexapod system properly. But when there is only one rotational position you are controlling and all axis are at a set relative angle to each other, there's not much reason I see in trying to run IK. Plus I personally wouldn't trust IK in a situation like this for two reasons. Reason one is that this setup looks very prone to running into gimbal lock situations if you're not careful, and in precision systems, you don't want the system you be on the fly making alternate routes to free an axis is that situation. Reason 2 is that there is that with the arm attached, you have fairly defined physical limits that are not axis specific. On most systems with hardstops, you will have electrical or software limits that tell the stage, "stop you are about to go passed your safe limit and hit something". On this, you don't have electrical limits, and as the axis are always shifting orientation, software limits would be very difficult, and risk damaging the the system if something is missed. Plus as I stated in my previous comment, unless you sacrifice one axis to keep a slight opposing force to an axis, you will have unwanted backlash to deal with. While this wasn't really designed with precision in mind, that is just the priorities I have when looking at something like this. Even something not requiring very high levels of precision, like a simple parts picker on a PCB assembly system, that backlash and the wear the teeth will experience over time would make this a no-go in my book. This is just my opinion based on my experience, and the field I'm in. Others with a different background and priorities may look at this differently, but if everyone agreed on everything, the world would be a rather boring place.

I had a very similar idea around 2012. The start of the concept was an omni directional, spherical, spiked wheel for use in tanks, as an alternative to using a continuous track. I had a different idea for the driving mechanism, though this one is smoother looking.

Stunning piece of engineering. Well impressed.

I completely agree with everyone here, the presentation and execution of the project is something to marvel at. The system is mechanically redundant as you have more motors (inputs) than degrees of freedom. Although this shortcoming, I think that this is a wonderful showcase of engineering, and someone will find such an actuator useful someday.

@exol511

2 жыл бұрын

Tbf dual motor/input for single linear/rotary axis are very common in machines as it allows to counteract mechanical backlash of the axis as well as more power without having to resort to a larger motor. Multiple small input gears into one large gear also allows for a larger than normal gearing in a single gear stage as it has more teeth engaged splitting the force (generally its problematic to have a large gear ratio as the teeth strength starts to be a limiting factor).
