excuse me sir I think the formula should be When the pink pulley turns P deg. clockwise (the green one is immobile) the orange object displacements are: Along X axis: ΔXp = - Pi.D.P/720 Along Y axis: ΔYp = - Pi.D.P/360 -> - Pi.D.P/720 When the green pulley turns G deg. clockwise (the pink one is immobile) the orange object displacements are: Along X axis: ΔXg = Pi.D.G/720 Along Y axis: ΔYg = - Pi.D.G/360 -> - Pi.D.P/720 do you think it is right?

Great animation of a mechanical concept - you have a good ability to visually present technical information! I've read through the comments, but still have a question on something that was addressed in one of the comments, but is still unclear in my mind. My question is whether the black timing belt is fastened to the orange block at 2 points, or 4 points on the block. I think the top part of the timing belt passes through the orange block, and the bottom part of the timing belt is clamped at either side of the orange block for this to work. Is this correct?
@thang0101466 жыл бұрын
Yes. One branch of the black timing belt is fixed to the orange block, the other branch goes through it. Thank you for your question. I have to improve my explanation in the video description.

This is not a core XY. For this design the belt is 4X+2Y long. For a coreXY there are 2 belts, each 2X+2Y long. This uses fewer parts but is more accurate.

Hi! How do you control the angle of the diagonal movement? Only turning 1 motor does a 45 degree movement, but how do you get this , say 55 degree angle? Thanks!
@thang0101466 жыл бұрын
Please read the video description. When pink pulley turns P deg. and green pulley turns G deg. the orange object moves: In X direction: ΔX = (G-P)Pi.D/720 In Y direction: ΔY = -(G+P)Pi.D/360 ΔY/ ΔX = tan(A) A: angle of desired oblique trajectory of the orange object. Solve these 3 equations to get P/G relation giving desired trajectory of the orange object.

0:05 Something is seriously wrong with this concept/animation. It breaks the laws of physics. How is it possible for the orange peace to move left/right on the blue axis? The belts would need to get longer/shorter. 0:05 Look at the 2 top-left gears. They work against each other. And the belt on the left side magically gets longer. It can't work that way.
@allyouaskfor3 жыл бұрын
The belt is attached to the orange block at only two points, not all 4 as the visual would make you think. The two lower points are attached while the two upper points are actually the belt passing through the block.
