The desired outcome of our final project was to create an autonomous robot that was programmed to move through a series of figures, then stop. Due to time constraints we limited the robot to “ drawing ” two figures, a five pointed star as well as a circle, on a piece of paper.
We decided to use the HSC912 microcontroller in conjunction with two DC motor/ encoder wheels. To make the robot autonomous a portable power source was needed so two rechargeable 5V battery packs were used. To get the robot to draw an ink pad was mounted to the left wheel. As the tire rotated ink was applied to the wheel resulting in the drawing of the programmed shapes.
