Drumming Monkey Project

Project Description

With a whopping 54 pieces this build can be a big challenge! 

The drumming monkey uses cams to change rotation force into a linear force moving the drumsticks up and down. 

He sounds great and looks amazing when he is finished! Give it a go yourself.

Explanation of a cam

Cams work by changing the rotational (circle) force of our handle or motor into a linear (up and down or left and right) force. They are made from smooth unsymettrical shapes which can push up and down on beams or other objects in our mechanisms. You can see it in action below:
