Building Instructions∗

Create Hank's main chassis as shown in the next two steps; this will hold the RCX, the motors, and the bumpers.
Attach the shafts as shown. Hank's treads will be mounted on these shafts. The front pair do not rotate, while the rear pair
should. Don't push the front pair all the way in; you'll need to fit the tread wheel and another bushing on the end.

∗ The parts included with RIS 1.5 are slightly different than those in RIS 1.0. If you're building Hank using RIS 1.5, you
should use two bushings instead of the green pieces in Step 2.
