can you upload a video


KEEP TRYING, I think you would win if it worked


Nice try, though!


did you make the image?


Great idea! Keep trying.


Great job but keep trying! ;)


Good effort. Did you consider moving the picture and having the dispensing/building mechanism stationary?


Very cool. For precision, you could try varying the gear ratios. For example, if you put a small gear on the motor with a large gear on the wheel or whatever you're moving, the wheel or other thing will move less but more sturdily on the same amount of motor rotation


@pharrmac: Yes, I made the image myself to enable you to imagine the result of the project if I would manage to make it work.


I think I can help you for the precision of the motor: Try to use gears. Good luck!


@BusterHaus: I don't understand the advantage to make what you said (in addition, that would be more difficult to conceive)


@yosho27/lama-mantis: Thanks for your idea! I am going to change gears and try again.


We'll its to bad it didn't work but YOU STILL WON THE CONTEST! Congrats!


did you try giving the reserve more room? also using gears could solve the robot's second problem.

Here is my second project I intended to present for the “artbot” challenge... but I failed. The robot should build a picture “block by block” on a surface whose dimensions are 20x23. It uses three motors: the first one is used to choose the color of the brick (it makes the bricks reserve move and place the right color in front of the corridor), the second one is used to make the bricks pass through two wheels and push them to form a line, and the last one is used to push the line when the line is finished. I have two problems: firstly the first motor is not precise enough and does not align well the bricks with the corridor and secondly the reserve hardly moves and is sometimes stuck (I have never understood why).
