Despite drawing being very important in children’s development and very important to many adults, many do not have the ability to draw due to a lack of fine motor control and other issues. The solution to this problem is a simple device that allows a pencil to be controlled with large, imprecise movements. A Myo can be used to control a drawing device with simple and easy movements.

DrawingBot makes drawing easy for people who lack the simple skills needed to draw by helping people create art without actually having to hold or precisely control the pencil. The final iteration of the project uses servo motors to move a pencil connected to the servos through multiple joints. The servos are controlled by a Myo. The drawing device was originally controlled by a timing belt and then a gear and rack until we reached our final idea which we prototyped many times. Though mostly complete, the servos movements must be corrected as well as the control system for the device.
