The design for the robot is modular, the motors are attached to a 4 pin connector which allows for different brains or controllers to be attached to the robot. The brain consists of a Adafruit Pro Trinket 5v connected to a dual full H-bridge IC. Which allows for control of both motors and speed control through PWM. The robot is powered through a 3xAAA (4.5v) battery pack from a flashlight with an ON/OFF switch.
Simple autonomous navigation: Moves forward until obstacle detected, turn right, loop. I have plans on adding a more throughout navigation program.
