"RobBox 2.0" is a humanoid robot which is able to stand up, walk and fight against objects completely autonomously. It uses three sonic sensors to scan its environment and moves accordingly. It detects if it has fallen down, by reading push-buttons located on its front and back. An LED-matrix inside the head is used for its mimic. The main controller is an Arduino Mega. Moreover an SSC-32 is used to control the 19 servo motors. The whole robot is built out of parts you can buy online.
