The Robotwo is inspired by fritsl "how to make your first robot".
My goal is to let the robot drive around my living room without any human interfering.
However my living room being a bit of mess sometimes thats not so easy.
Robotwo uses 2 switches configured as a bumber, and the ultrasonic sensors SRF05. The SRF05 is mounted on 2 servos so the sensor can look horizontal and vertical.
