Beetle Robot
This beetle robot has 6 legs with 2 servos controlling
each leg. The robot can move forwards, backward and turn
to the right and left at many different speeds. It cannot,
however, "crab" sideways due to the limitation
of only 2 servos per leg (2 degrees of freedom, 2dof).
The robot can be controlled using a radio remote controller
or in autonomous mode, it moves under its own intelligence
by detecting obstacles with a pair of 'whiskers'. The
robot is used in undergraduate experiments where ten of
them are shared between 20 students who then program them
to race, one at a time, through a maze. The beetle uses
12 integrated servos (Futaba S3003) and 4 Basic Stamp1's.
One BS1 sets up an intelligent real time clock which synchronises
the other Stamps. A second BS1 controls the 6 servos of
the left legs. A third controls the 6 servos of the right
legs and the fourth is concerned with strategy after reading
the 4 states of the whiskers. The students get a grounding
in real-time systems, concurrent programming, artificial
intelligence and control of mechanical systems
