    James Bruton I have an excellent idea if you are willing to try it! Attach a camera to the head of the puppeteering rigs, then hook it up to a VR headset so you can see exactly what the robot sees. Then, make a suit that can detect roughly where your body is instead of the smaller controller things. That way, it actually feels like you are the robot. Move your hand forwards, and the robot moves it's hand forwards. Might be a bit strange as there would be a small delay between you moving and the robot moving, but it would be super fun I reckon, even if it doesn't have much of a practical use! I would be happy to help with some of the design and code if you like.
    I completely understand that it would be quite a large project to attempt, but the result would be super fun! Plus, a human-based controller suit could be SUPER handy for other projects later on

      I think the robots can't really move fast enough for it to work very effectively. It would be extremely disorienting to have the robots arm lagging behind yours by quite a bit and I bet it would lead to a lot of nausea.
      Definitely a cool idea, but I feel like it may not be very possible.

    • @tiporari
      @tiporari 4 роки тому +1

      Latency of limb movements won't cause nausea, only latency of camera movement if the head is moving in relation to headset tracking. You can just create a fixed viewport scaled 180° and move the "player" viewport across the field of view (which is plenty fast). Easy to solve at a slight cost of resolution, which people tolerate just fine.

    I think it would be a fun challenge, where operators would be in a different room than the robots, controlling them with a POV perspective. Maybe doing something like preparing an easy meal (a sandwitch maybe?) or building something with easy to grip blocks. Either way, those robots look awesome! Can't wait for more videos! :D

    I love the puppet rigs. I have always thought this approach would make operating heavy machinery like cranes and excavators much more intuitive and precise to control. Particularly if you incorporate force feedback in the axis.
    Consider putting the wearer "inside" the puppet rig, and allowing them to control an exosuit as an assistive technology for disabled persons mobility.

    It would be interesting to see the gripper switches changed to something like a linear potentiometer that would allow you to control how open or closed the gripper is. Then you would still have the gripper stop adding gripping force once the hall effect sensor has reached its desired value and at that point it would ignore the value of the linear potentiometer if it were to move in the direction that would command the gripper to grip tighter.

      Basic programming is all you need to get started, the more advanced parts are things you learn as you go. You can't wait with doing stuff until you have mastered programming, then you'll never master it. Best way to learn is through actual practice with actual goals and projects.

    You should add gripper rubber along the inside of the "fingers" so that they could more easily hold on to things.!
    Can the robotic arms move up over and down to the box?
    It looked lie you needed to move the elbow joint further our from the body and then turn the joint sideways almost 90 degrees, it is a stiffer way than we humans move, but if the range of movement is good enough it should be doable.
    Fun challenge by the way, build on that, just change the test a little to require more of the movement the bots are able to do and add more test and you'd have a fun game at shows and such.
    One test could be to remove a hat from the bot, then push a button in an award spot, pick up and place the balls, blocks and more.

    • @foldionepapyrus3441
      @foldionepapyrus3441 4 роки тому +1

      Didn't notice any deliberate pauses in code to slow things down - I expect its just the combination of input lag (it takes some time for puppet rig to read convert and send data) and the decoding and acting on it at the other end. Mostly in that last part as the robot arms do not move all that fast where the little puppet rig can cover the whole range of movement almost instantly, and the robot arms have motion smoothing as well so the acceleration and deceleration will be gradual. Doesn't actually look bad to me though, clearly not 1:1 'real time' matching of the puppets but its pretty swift.
