Those electrical powered springs did raise this project on another level. Insanely good RnD James. I really enjoy this series. Thanks for your huge effort!
@@GeeEmJay probably, i mean disney are pumping out shitty live action films and upping merch prices and buying out anyone remotely better than them, they are trying to control media as a whole
At the end where you are pushing springy dog with a broom I was kind of expecting it to turn around and attack you. Turns out no robot uprising is happening today :).
I feel like he's right on the verge of having these things walk around, but it's in need of a massively complex code, and he's just one guy. Maybe an AI deep learning computer could help.
@@Sqoou_Too That would be a good idea but it would be even more complex than just conventional programming. For instance how would you train the AI? Normally you would setup a simulation and run it 10000s of times until it learns to walk. Then you could put it on the real thing.
Considering that humans walk around on two legs, I'm fairly sure that we're good at balancing. But we use a bunch of different things to help us balance, that when taken away, makes us unsteady… When something messes with our inner ear, it's causes rather a lot of balancing problems. I'm not actually 100% sure of all the things that the inner ear does, but considering that I know it uses a liquid inside a sealed chamber, with sensitive hairs to detect changes to the motion of the liquid, I think it's used for at least two things: The direction of gravity, and changes in momentum. When we suddenly can't see our surroundings: our balance can be negatively affected. It think this is because we tend to use our surroundings as a reference point for our own movement. But because it only has a relatively small effect on balance, I'd say it's just supplementary for balance. Although it should be noted: Spacial/Environmental awareness is pretty useful for navigating obstacles/just plain navigating. You ever try getting up to walk somewhere while your foot in asleep? It can be done … but not easily. I'm not entirely sure it the difficulty is caused by weakened muscle control, or just because there is no feeling on the bottom of the foot. And you want to talk about making it hard to walk? Try walking steadily without a properly calibrated sense of proprioception! That'll be a trick to see. And finally… (As far as I can think of…) There's force sensing. No… Not “The Force”, from Star Wars. I'm talking about sensing how much force your muscles are exerting. Hmm… When I try to think of a situation where you loose this sense, all I can think of is a limb that's fallen asleep and lost feeling, so maybe this should be considered part of that. But trust me, it's important! The good thing is, I think you've tried exploring the possibilities of using each of these senses in your various robots. However… Have you tried using ALL of these senses at once in a robot, yet? My gut says that if you haven't yet, then you will eventually.
Would it be a good idea for the leg opposite of the leg that is being pushed to step outwards? when you receive a push in person you don't right yourself just by pushing your leg down, you widen your stance to stabilize yourself. Just an idea, hope it makes sense. Great project anyways :)
Hi James! I saw a foot sensor made by putting an atmospheric pressure sensor inside a rubber ball. When the ball hits the ground the pressure on the sensor goes up. The ball was made by pour casting the rubber around the sensor inside a mold, which could be made on your mill or with a 3D printer.
Hmm, could you dynamically set the compliance value? So, if stepping on something is causing it to tilt too much in one direction it dials back the compliance on the leg that is throwing off its gate. In essence making the leg progressively "mushier" until its tilt comes back into tolerance.
Another great vid. Didn't realize you were a supporter of the robot revolution though. Do you think robots will be afraid of brooms or brooms will be their weapon of choice in the revolution?😁
That's pretty clever. It even gives the dog some balance without info about it's orientation. Having this as the starting point to finetune the balance should make it easier. Have you considered "compliance"? :D jk
I can understand how it is a fallacy that a spring that can hold the weight of the dog would not save power, but what about a spring that can hold half the weight, and drive it both directions? wouldn't that use about half as much power? or am I missing something? There do seem to be advantages to a system that can stand with low power consumption as well.
I am just some A Hole, but I would assume if you built logic to keep the body stable and level the legs just do whatever it takes to keep it upright while moving forward. I would also guess these are the steps to work towards that goal?
A few comments: a spring assisted leg is a really good idea, but needs a low rate. As your motors can drive in two directions, you can "offset" the motor torque by using a spring to hold the primary mass (a bit less than 1/4 of the total mass). That spring needs to be matched to the geometry of the leg to try to provide that
BTW one possible nice option for a spring assisted "muscle" is to use an pneumatic cylinder, and fit a much larger (volume wise) central pressure resevoir on the body. By having the resevoir volume much larger than that of the leg cyls, you get a much smaller change in system pressure for any given joint movement, and you can change the leg preload by changing the resevoir mean pressure.
Thank you for all your content, I always enjoy watching you as you develop and work on new ideas. I have a "what if" question on Open Dog, what if he had 6 leg's? I know B.D. has 4 leg's and its a great development platform, but if 6 leg's gives it more stability the platform may be more reliable. This is a general question not a recommendation from me. I love the 4 leg Open Dog.
As I understand, this kind of virtual spring is only applicable to gear boxes with small reduction ratio and is not applicable to worm gear reductors. Is it possible to simulate springiness with sensors on feet? Like if sensor shows too much pressure, microcontroller commands motor to move leg down a bit or slow down upper movement if leg moves up.
Why not motor -> springy coupler-> leg, with rotation encoders on both shaft of motor and on leg, and use that for the compliance? As in: use a torsion spring coupler. Probably less than 30 degrees of rotation overall would be plenty... just enough so you can tell desired and actual angles are different, and if you're updating fast enough -- the new Teensy 4.0 is 600 MHz, 5x faster than 3.6, and 9x faster than 3.5 -- you could easily do all the stuff you need to.
There is a state variable you're leaving out: force. Think of the sum of the forces applied to the floor or surface. There is a total force required to hold up the body, and in the different configurations of the feet on the ground and off. When you lift one foot, the two diagonal feet ought to be holding up all the weight but the foot diagonally opposing the foot that's up is still being driven without regard to the force it really should be applying, which should be near zero. When it's not near zero, the force it applies pushes the frame over, causing the body to heal over towards the foot that's up. When that foot comes down the body has been torqued toward the foot that's coming down, so the contact with the floor is "uncoordinated" with the goal of keeping the frame level. Expressing this mathematically would be a stretch for me. I hope this is comprehensible. Can you see what I'm describing? Great videos!! Have you thought of doing all the initial design in virtual space? Chris
I thought compliance is for when the feet touch the ground and not when in the air. Also when adding sensors to the feet you could also control them using a target pressure. Namely if both feet touching the ground experience the same pressure (skewed a little maybe if the center of mass is not exactly in the middle) the robot shouldn't tilt. Also if you want to tilt in a certain direction you could raise the target pressure on the opposite side (and lower on the other side). Changing those target pressures can either be done in open-loop or closed-loop (using a PID controller or something). This might require switching control strategy, namely using position control while the feet are of the ground and pressure control while on the ground (when the pressure sensor exceed some minimum pressure when touching the ground).

maybe boston dynamics will be thinking: "building the robot takes us years, and james takes days" nice video James!
You could add springs to the legs, but only use springs strong enough to only carry half the weight. This way both lifting the feet of the ground and supporting the robots weight while on the ground should require a similar current. This way the maximum of the absolute value of the drawn current should be smallest and put less load on the motors.
Please have another look at adding springs to the legs. Now the motors only work a supporting the robot, lifting the leg (fast) does not require much work. When the springs take half the weight of the dog, the motor can drive them into both directions. Nature does this too, the tendons are springy.
wow, the robodog blueprints are open source enough now for hobbyists to make them if they really wanted to? I thought they were used as military pack mules? Wouldn't other countries use the open source to make their own?
I would like to see this project move faster, perhaps James has too many projects at one time. Is it just me or did he used to finish a project before starting ten more?
I'm working on it now, but I'm trying to produce solid videos with actual results in, so it's takes time in between episodes as the projects get more complicated.
@@jamesbruton Don't get me wrong, I love what your doing. But I want to build my own open dog and a video once a month seems like this might take years. I'm 62 years old, almost 63, hope I have time LOL. Is it safe to order motors and controllers and start playing around with them or are you likely to change everything? Is it too early still to start machining the aluminium parts? Thanks
@@wkinne1 Wayne, his dog as it stands this second could easily walk so I'd say just get building to you. James is merely working out software issues and figuring out balance and is trying to experiment with different feedback mechanisms. The engineering of the chasis, motors, board layout, etc is just fine as is. Given enough time, without ANY changes to the dog, he could easily program it to walk, run, etc and it would perform similar to boston dynamics bots. He's just exploring his options right now on code and feedback is all. If he were willing to write 50k lines of code his bot would arrive. He likes simple code though with minimal lines of code to deal with and prefers 3rd party libraries to coding from scratch.
@@artbyrobot1 I'm going to buy a couple of the motors and a controller and start playing. I think I'll start slow, learn as I go and hope he makes progress a little faster than me, thanks for the input.
You should do a quickie vid where you make music by sliding little drums in and out from under the test robots feet, using the sound of the mechanism as the beat.
Build some form of distance sensor in to the foot it would let the robot know how far his leg can go down until it hits the floor this would make a smoother more predictable ooeration Combine it with a pressure sensor and let the motors drive backwards until the pressure beneath each foot is the same
I love the fact that you can hit it with a broom. A true robot. As the the springs to hold it up, I think the key is the the springs to take half the weight. So you would need to pull up with half force, or push down with half force. Might be enough to get it to stay up with 2 feet with the existing motors.
Is it really an advanced robot if it can't stay upright after being beaten up by a broom and pushed around? I reckon he's taking inspiration from boston dynamics!
In a year or two we watch boston dynamics and say: "Hee that is how James did that before".Why do I get the feeling that if James had like 25% of the budget of Boston Dynamicts, we would have a fully operational c3pO or Sonny NS-5 by now.
budget is not holding him back. he bought the best motors and motor controllers money can buy. Also has a full blown cnc machine to make metal parts now and welding tools top of the line no expense spared. How is budget an issue at all? It is his unwillingness to create long and sophisticated coding algorithms that is holding the project back and you can't blame him for that since that takes years of time and he likes to race through projects fast as possible.
What about "cam" or excenter on upper second joint? When you controll lenght or pos of second joint, then you controll vector of pushing, forward or back... impresive work, thx for share.
Why, why, why are you wasting time with crappy compliant joints. You have just wasted hours of your time while what you should have been doing more with the imu. You don’t need foot switches. Every time I watch these videos gutted that your not progressing 🙃
Hey James, great video as always. Been watching since the beginning of your R6 droid. One question though: How do you choose what color scheme to use in your projects?
What if you used orientation sensor and basicly calculate a new posision with the way it was leaning to adapt? not an engineer so idk how this would work out, but might give an idea.
