Peter Ellison made this new robot. It uses the Rabbit controller. Here is he giving a demo.	It has a Polaroid sonar on the front to get range information. The sonar is mounted on an R/C servo. The small yellow pulleys on the wheels are for encoders.	It uses DC gear motors for the main drive wheels.	It uses drill batteries.
Another view.	Another view.	Top view. You can see the Rabbit module on the carrier board. There is also a slave board and a motor driver board.	The slave board has a Basic Stamp and an H-bridge driver board. It looks like this board is driving the R/C servo for the sonar.
The dual H-bridge driver for the main motors.	Jeff Sampson brought his engine/generator project. This is the front view.	Back view. The starter relay is hanging on the wires on the left.	The flywheel cover removed.
Bill Arden gave a talk on his new demonstration project.	He is making water based devices that will represent electronic devices.	Bill is building a switching power suplly that runs on water pressure. So it has a square oscillator driving a transformer. The other side of the transformer has a rectifier and filter capacitor.	This is his "MOSFET".
This is the output stage. It has a "capacitor" and a "diode" on a "PC board". All done with water.	Alan Kilian describe his round stepper motor project. Just like Animanemone, but round.	This is Alan's stepper motor circle, his Trippy robot and his Oscar robot.	Alan is explaining the holonomic drive on his Trippy robot.
Terry Schumacher explained his robot. It is a prototype for a lawn mower robot.	Top view of robot. You can see a Mini RoboMind board, an LCD and two custom boards.	Another view.	Driving it around on the tether.
Peter's robot and Terry's robot.	Terry Schumacher brought in these two robot books.	There was some discussion about ignition systems.	And some talk about mapping.
And Bill couldn't believe someone would put a complete battery charging system on the free pile.
