      You could make the weight shift automatically depending on which linear motor you enable? I.e. moves forward before moving rear wheels etc.

      It does a good job, however needs more damping indeed. Switching point of interest instead of accurately following it is what's needed.
      And personally I'm used to a signature steady wide open shot with a lot of machinery in the frame. Change is not always good.
      A lot of videos today are dynamic and shot from a handheld cam. James style stands apart and that is good IMO.

    It's a VERY good machine to carry a quite massive load and for keeping it level and stable. But for it carry you a beer while you're feeling lazy... well I think it would be warm by the time it got there lol. You did mention that it was overly complicated, and I agree... for SIMPLE tasks. But it really is the perfect design for what it was based on (cleaning the stairs)

      If I were to do this project, I would cheat and mount a track on the wall that the robot could attach to and drive itself up the wall like one of those stair-lift-chair things.
      Or attach and detach itself to an installed winch or crane.
      That would only help for a home use that's planned ahead of time like that - not really as robust as a solution as this robot that could go up many different types of stairs.

    At least, I think you can automate the stair climb with 1 sonar sensor on the front:
    You still have control of the driving of course. You can drive it up to a step, and hit a button that will start the stair climbing (maybe with the same button to stop the auto-climb so you can take over too).
    The program will first make sure it's close enough to the step, maybe even bumping into the step.
    It will then raise the front section until the sensor doesn't detect a close object.
    It then drives forward a set distance, stopping if the sensor gets too close to the next step (if there is one).
    I'm not going to write out the whole thing, but I think you can get the idea for the algo from this. Just one sensor needed! :)

    a couple rails with a section of teeth in the middle would make it easier for a small robot to quickly climb the stairs. depending on size you could get it to corner on the rail and even a weak, slow climb would still probably be faster than all the stop and go with this bot. this robot is amazing in its own way and if it was only a step or two it would be fine but 7 min is a while and then you need a good bit of sensors to keep it from just driving off the edge.

    Thank you for your video, as I also need to make a 'scooter' that can go up stairs, and I am thinking of using a segway type device that has large diameter wheels and you can shift your weight forward. It needs to go faster than you can do it yourself with your legs or it won't be useful....It would be great if you could figure this out. The track system might work if it has large diameter more like a wheel. Cheers, Jack
    btw, a simpler method is to fire a hooked cable to the top of the stairs and just winch yourself up, doesn't need anything but a single winch and some wheels. Can go back down too. And very quickly too if you don't mind some bouncing.

I had a thought though, and I'm not sure if I'm missing something (in which case, please correct me), but if you have the moving mass that can change where it balances, why couldn't it be just two segments? Like, it puts one segment up one step, shifts weight onto that one, lifts the back segment up, transfers weight onto that one, etc.

    Make the weight mechanism have 3 stages, when you lift the first wheels the system automatically first has to have the weight on the first stage, when you lift the middle the weight automatically moves to middle, and when you lift the last wheels the system automatically moves the weight to the last stage, this removes two buttons and stream lines the process so that if further autonomy with sensors may be easier.

    I think it only needs to drive the front pair of wheels when the middle pair is at the same level as those front pair.

    Rather than sensors for detecting the distance to the next step couldn't you use switches on each side (front left and front right) and let the robot bump into the stair like the early roombas did to detect the stair and then orient itself correctly (straighten out and then move to the correct distance for ascending)?
    Couldn't you also automate the ascent process rather than having to control it all manually with a remote? It seems like it's a fairly repetitive task that would be easy to set up macros for each of the different movements and their timings

  • @xaytana
    @xaytana Год назад +1

    For a vacuum/sweeper, this kind of mechanism makes some amount of sense as it sweeps each step before progressing. But for anything else that needs continual progress up a flight of stairs, tis is insanely inefficient. Unless legged robots become more prominent where they can actually _step_ up the steps, any other form of robot will have to be bound to a rail system to retain any amount of movement efficiency; that's just the reality of robotics at the current moment. Sure there may be some atypical wheel and linkage designs that makes traversing stairs more possible, but you also have to consider what sacrifices those atypical designs are making when it comes to typical movement. Honestly the best of both worlds, stepping efficiency and rolling efficiency, might just be a Spot on skates, but then you're also pretty deep into hardware costs just so it can occasionally step; though this would be good for terrains where wheels don't make much sense either.

    • @greenanubis

      All those are fair points. And James probably thought of them, as did many people for many years. Boston Dynamics Spot can handle stairs. But hey, if stair lift is what you need for your robotic butler to get you a beer, thats a small price to pay i think.(btw, if you want "typical" movement, human movement, then you have to go with legs)

      @@greenanubis Did you comprehend any of the comment? They already stated legged robots are what's efficient for stairs, why be utterly redundant in your statements? They also stated the fact that a non-legged robot would optimally use a rail system to traverse stairs efficiency; again, comprehension issues? Your argument of typical movement also has no basis in anything, they had stated that _atypical wheels and linkages,_ such as tracks or treads, sacrifice efficiency when it comes to typical movement just to traverse large vertical disparities, such as when you have multiple secondary wheels around a primary pivot to climb steps via rotation of the secondary wheels, you'll be sacrificing rolling efficiency due to much smaller wheels by comparison to a singular wheel that fits the same radius from pivot center to the secondary wheel's circumference, thus your 'typical movement = human movement = need for legs' argument is entirely baseless and counters absolutely nothing they had said; again, did you not comprehend a single thing? Where did this argument even come from? You do realize typical movement for a wheel is rolling, yes? Are you high or just a moron? Stair lifts aren't the only rails stairs have, btw, not that any robotic platform would interface with a typical stair lift anyways but rather use its own rail with open ends and without other devices on the same rail; again, another moronic statement. Maybe rather than be an illiterate moron, you go educate yourself a bit.
      As for James thinking about movement efficiency, absolutely not, he saw a robot and made his own lesser version of it, as he typically does. As for other people having thoughts of movement efficiency, obviously it's not a primary topic, nor a topic widely discussed, if even a topic of consideration; reference atypical wheel and linkage designs that sacrifice efficiency in their primary mode of movement just to climb stairs, tell me where the movement efficiency is, reference the fact that legged robots might have a more efficient mode of movement on paper but are not efficient in the slightest due to _rotational_ motors being used for multi-hinge legs and gaits, there's reasons why natural joints have limitations in rotation and why muscles are linear devices in vertebrates. Tell me how cock tastes, because you sure are sucking off a lot of people right now.

    Cool build but guess the beer will not be cold once it arrives 😉 Thanks for sharing 👍🏼

    I'd like to see a Treadwell type droid go up and down stairs. Using the arms to help start going up. Then tilting the tread bed at the base of the body so the body remains upright.
