What does it do?
My Goal was to come up with a design where all the speciality parts could be ordered for under $20US.
The bill of matirels (BOM) looks like this:
2 ea 9g CR Servos
2 ea Wheels for the Servos
1 ea 4xAAA battery box with switch
1 ea SR-04 ultrasonic range sensor
1 ea Arduino IDE compatable ATTINY85 based controller board. Such as a Digispark, Iteaduino or any one of the similar devices.
