Here are some of my robotics projects and a link to the Boise Robotics Group, or BoRG
The Boise Robotics Group
Basic Stamp Controlled Lego Robot
I married a Basic Stamp 2 to a Bob Blick H-bridge circuit to operate this robot. It scans for a flashing IR beacon and drives to it. It will not cross black lines and uses a bump sensor and IR proximity sensor to avoid collisions.
This is an example of the robot we make at the Boise Robotics Group (The BoRG). The controller is a locally developed version of the Parallax Board of Education and was described in the March 2006 issue of Servo magazine. The major difference is that the BoRG uses a larger bread boarding surface. Members of the BoRG make their own BoRG Boards from scratch. Bolted to the fron of the robot are two line followers, also designed in-house with the BoRG. To help keep the price of the robot affordable, we use plastic peanut butter jar lid for the wheels, like Robert Nasel recommended in the December 2000 Nuts and Volts magazine.
BorgBunny was my entry for the first BoRG robotics competion in 2004. BorgBunny uses a Basic Stamp 1-IC and the H-Bridge designed by Bob Blick. Clicking the bumper signals BorgBunny which of its three competitions it's competing in this time. So instead of downloading a a new program into it for each competion, I just powered it up and pressed on its bumper 1, 2, or 3 times.
Robotic Ultra Orb
I removed Jimmy Neutron and the radio control from an Ultra Orb toy to make this robot. The H-Bridge driving it is Bob Blick's design and the controller for it is a BASIC Stamp 2. The problem I have with this robot is that it rocks back and forth when it starts up, turns, or slows down. It's going to take some time to ramp up and down its speed properly. That or give the robot training wheels.
The Cutting Board Robot
The Cutting Board Robot is an early demonstration of robots on the cheap. A platic cutting board, inexpensive, battery operated screwdrivers, and plastic plumbing caps form its base. The rubber bands on the wheels gives it sorely needed traction. The controller is a BASIC Stamp 2 and Bob Blick's H-Bridge.
Near Earth Asteroid micro-rovers
I published an article on these rovers in the July, August, and September 2005 issues of Servo magazine. The rovers are based on a design described by Robert Nasel in the December 2000 Nuts and Volts magazine.
Shoe box Rover
A plastic shoe box and battery-operated screw drviers make up this robot. A four-channel digital toy RC operates this rover. It's four switches have been wired up to external switches and relays. The BASIC Stamp inside interprets the buttons pushed to control the rover. This lets four switches send eight commands. The sonar in front scans for obstavcles and the rover will avoid then, inspite of the command it was just given.
