Greg has been working on a new Object Grabber robot. The new
design uses a lead screw to move its gripper (yet to be installed) up and
down. The sensors will also move with the gripper. By knowing
how far the sensors have moved up after looking over there top, the type
of object can be identified.

Ed brought his Object Grabber robot to show some new folks at the meeting
that haven't had a chance to see it. It also uses a moving vertical
slide system to measure the objects height to determine what is point value
is.
Here's is a novel crank and plunger spring system designed make a economical
walker leg.

Some more Robo-Magellan project parts. This is a pan and tilt
system for moveing a CMU cam, sonar and IR sensors. These are to aid in
the final search and approach to the navigation goal. The servo motor
mounted above the sonar in the left photo is to spin the optical filter
disk shown in the right photo. When mounted in the enclosure, the
filters will adjust for the variable outdoor lighting.

Dennis is now using a AVR controller in his Critter Crunch robot project.
Also featuring high performance surplus batteries and a UDN2998 3 amp motor
controller chip.
