Robot builders often find that the trickiest part of a robotics project is making
the wheels. First you need to find a suitable tire/wheel combination, then you
must figure out a way to attach a sprocket so that it will handle the torque
of a geared-down drive motor.
The 12.5-inch wheel has a 3/4-inch bore with a 1/4-inch keyway. The inflatable tire is 2.75 inches wide. This wheel works well on both pavement and rough terrain. 3.4lbs.
