Improvements Upon the Mouse’s Construction
We explained that one of our goals was limiting the size of the robot, and we
achieved it through a single motor steering drive.The limitation of this setup is
that it doesn’t allow you to control the direction of the robot, which results in a
mouse whose movements are very predictable. Using a second motor to control
the front steering wheel you can enrich the behavior of the mouse with some
random changes in direction.You should redesign and enlarge the body of the
robot to make room for the second motor.
