Equipment:

The ECP Rectilinear Plant is used to illustrate the behavior of mass-spring-damper systems.  The drive motor on the left is used to investigate forced responses, while the three masses, three springs and single damper can be arranged in a variety of formations. Encoders linked to the masses communicate the three mass positions to the computer for analysis.  Labs 4 and 5 will use the ECP plant to take a look at step responses, free responses subject to initial conditions, and identifying modal frequencies and mode shapes.

The Pendubot is a two link underactuated robotic pendulum, developed at UIUC by Dan Block.  Lab 7 uses this pendulum to compare experimental results to both the nonlinear and linearized 4^th order motion equations.  Although this lab investigates only free responses, a demonstration will precede the experiment to show the Pendubot's swing up and catching ability to balance at two unstable equilibrium positions.
