When I was in middle school I saw this robot documented in discover magazine. I was absolutely fascinated. I had been interested in mechanical design, and the concept of spherical motion transfer and and control totally blew my mind. It was that article that led me to work in robotics. Thanks to those that worked on it.

I'm amazed to only now get this in my recommendations yet this concept is already quite old and I haven't seen an update on it in 5 years. So with the new availability of electronics and microcontrollers, I'm guessing this should be even easier to engineer in our current day and age. The question then arises, why haven't we seen this design being adapted and improved upon?

Dylan Klavins (our former mechanical engineering lead) directed the design and construction of a robot using some of the concepts from this video's design at our high school robotics club a couple years ago. It is not an actively stabilized tall robot like the one in the video, but rather is a lower, faster robot with four balls designed for fast, holonomic navigation over difficult terrain. Here is a video showcasing it: kzbin.info/www/bejne/oGGcga2ji9KtgNk

Very cool, I remember building this thing in Uni. I wonder why there hasn't been any notable further development incorporating this Ballbot's concept?? One problem I bet is maybe it's power hungry, actuating the motors constantly in an effort to stabilize the structure due to its inherent unstable idle position. Thus leading to not being economically feasible or user friendly, cuz you gotta charge the thing all the time or need a huge battery :(

that sway in the jaw-axis when moving probably is just a oscillation in the control loop but it adds character. It gives the appearance of a walking (or skating) motion that to some extent anthropomorphizes the machine.

Considering the shape (height) of this robot, it seems like it would be advantageous for it to have a solenoid-shiftable mass near its top, to give it the ability to lean just a little. In its current configuration, it seems like it could quickly destabilize and fall if it were to run inti anything (or is pushed into anything). Having a secondary means to rebalance itself in a worst-case scenario seems important, and would also open up quicker accel/decel, higher movement velocity, and potentially better ability to handle uneven terrain. All the balancing stuff is really cool and great tech, but it’s 2020 now and lots of people have been building single-ball balancing robots and they do well up to a point, until they topple over. A secondary balance mechanism could be the missing component that pushes this from cool concept to viable product.

OK so this obviously could make for very agile ball joints in robotics, a hip joint with good stable sway could make bipedal walking a lot easier. A binding mechanism could be a simple cup with 3 of the same wheels but free-rolling, with an axle extending from and tentioned to the driving assembly. With it bound from each side and basically a universal joint at that point a computer can calculate the needed input to the ball wheels to drive an appendage in the right direction.

Anybody who has played with some '2D' balancing robots (like Segway) knows that things go a bit crazy in such cases indeed. Maybe better control software can make it better. But I do not really see a big need for balancing on a ball. You could easily make a small stable low wheeled platform and then put an active approximately-balanced high vertical robot on top of it. This makes the balancing much more forgiving because the platform can still provide some extra torques where needed. Compared to a human we put our whole foot to the floor and add balancing because we are very tall compared to our foot size. The ball-robot is more like balancing on the tip of your toe. I do like the high narrow robot concept a lot though.

i love ball bots, but the name is a bit too humorous for soliciting the emotions that are required for appealing to serious minded investor types. what i mean is that the colloquial 'ball' if often used to mean 'testicle' of the male of any species, especially human males. So this name alludes to the collquial for 'testicle bot' . In this case, the robot is then thought to have 'one' ball, as opposed to ' two balls' or a 'pair' or 'pair of nuts' which , is often used to refer to the number of testicles of a human male. And , of course, this doesn't even begin to approach the allusion to the human penis , a topic of much humorous discussion. That would be bad for getting money to build this robot. Essentially I'm saying that , on a practical level, calling this robot a 'ball bot' is going to elicit a lot of snickering from young people and people who laugh at gonad humor. They may even start calling it 'dick bot' or a 'penis bot' or a 'cock bot' . This would not be good for soliciting sales or investment that is always necessary to help accelerate the development of any fine robot. I would like to see this robot become more popular. So, please call it something different. For example, call it a 'sphere bot' or a 'globe bot' or a bowlingbot , anything but a 'ball bot' . This would likely help you actually get (more) money from investors.

Why build something inherently unstable? You know, there's omniwheels and all that. THIS is how you waste research time, money, and man-hours.
@Spirit5328 жыл бұрын
Anthony Dach But remember, for this robot to be of any use it will eventually carry an unbalanced load, which will take a whole lot more energy to keep steady. Jets are actually very stable, and most have a fly-by-wire(or in this case fly-by-liquid) system if something goes wrong(say, heading/altitude hold). And again - your attempt at refuting my argument fails because you suggest that this system will be stable most of the time - which it won't. Unstable systems do have a much faster response - but at what cost? Nobody's going to need, say, a patient-observing robot to dash to someone when they press the emergency button - a camera with an epi-pen or two won't do you any good. Nor will this transport any large payload - it's simply too difficult to balance. Also, what do you mean by "reducing power consumption when moving"? Yes, leaning will get you some momentum, but that momentum will be that of an inverted pendulum - to crash to the ground, a stable position. You'll have to work the motor continuously, both forward(accelerating) and back(braking) to keep you from either falling to the ground or stopping completely due to an incorrect control loop. I do know what control theory is, so please, don't underestimate my chair-to-chair combat skills.
@Spirit5328 жыл бұрын
Anthony Dach If it's unstable, there's absolutely no way it can use the same amount of energy, as I've said, the center of gravity will be offset, and so will be the wheel, and the rest of the weight, and so on, and it keeps getting more unstable the more you add on. Right now I still don't see an advantage to a very unstable inverted pendulum system with absolutely no load capacity and a constant need to use power to be stable(vs. say, a carefully selected wheel platform with less friction and latching brakes).
