Chapter 15. building the T-R3X

The T-R3X is an ominous surveillance robot in the shape of a Tyrannosaurus rex (see Figure 15-1)! It walks on two strong legs, wags its sharp tail, and bites its prey with powerful jaws.

As you build this robot, you’ll learn another approach to building a weight-shifting biped walker. But be warned: Keep your fingers far away from its teeth!
