Scarab is a robot that makes use of two touch sensors
to detect obstacles. When its antennal (touch sensor)
detects an object in its path Scarab will go backward
first and automatically follow a twostep maneuver to
help it overcome the obstacle which can be a
combination of ?Left Turn? ?Right Turn? ?Reverse? or
?Stop?. The Scarab robot can be configured with
different sets of movements.
