Over the years, our group members and collaborators have experimented with
a number of unique robotic devices. The Pachinko Machine may look very
different from the team of three Nomadic Scouts, but
the underlying algorithms all rely on configuration space techniques to
induce these robots to manipulate objects.

These three robots guide a convex object (read: foam triangle) around an obstacle course. Their main challenge is to keep the object captured at all times: no matter how much it wiggles, it cannot escape from the cage formed by the robots. The current implementation includes a state-of-the-art visual localization system composed of three cameras mounted on the ceiling. These cameras are equipped with infrared filters that respond to distinctive patterns of lights emitted by the robots. A binary vision system (developed several years ago at a lab in France) makes it possible to accurately compute the positions of the robots. With the localization system in place, the robots no longer stray off course...

This device is a reconfigurable parts feeder with an array of pins. It was dubbed the Pachinko Machine, after the popular Japanese pinball/slot machines. The gizmo is also reminiscent of the Plinko Machine on the game show The Price Is Right.

This gripper has an innovative design consisting of an array of pins each of which has one degree of freedom. It was used to demonstrate grasping and in-hand manipulation algorithms for 3D objects.
