We had to make a robot that was mounted on a wall. It had to pull a minimum of 100 grams following all the rules that were given to us.
Our pseudo code
Create robot that is supported
Create Tread strip that carries the cup with weight
By using the tread strip, the motors at the top connected to the tread strip, will propel the treads in a circle to lift up the cup with the weight
Theoretically, should work.
The max 400
what we learned
The treads work more than strings and pulleys. build a large base to support the robot. learn to follow all directions to not have to redo the final project.
