IRBot - My first Robot


This was the first robot that I ever made. Click on the picture above to go to the pages that fully describe it. It is Stamp I based and uses hacked hobby servos.

My first Hexapod

Bugbot is also Stamp I based. To date, this is my only walker - I've been busy doing other things! It uses a modified tripod gait that is surprisingly agile for a simple three servo walking robot! Click on the picture above to go to pages that fully describe this project.

Evil Empire
Evil empireEvil Empire
Evil Empire is my entry into the TRCY robot combat competition. This is sponsored by The Robotics Club of Yahoo which is an ecclectic collection of robot haves, have nots and beginners. It runs using the Parallax Basic Stamp II controller on one of my Stamp II boards. The code is one based on the principles of Subsumption Architecture by using finite state machines to simulate a multitasking environment - here's the code. Here is the Subsumption network diagram.
Parallax BoE-Bot
Parallax BoE-BotBoE-Bot
The BoE-Bot is Parallax's latest entry into the "Stamps in Class" curriculum. Its a neat little robot with two hacked servos and a BoE (Board of Education) for a controller. It comes with IR proximity projects, light detection projects, speaker and Stamp II. The robotics program is layed out in a class like structure by programs. The robot above has a whisker bumper (my design), light and IRPD capability. It is programmed using my subsumption programming approach. Here is the source code for BoE-Bot.
Speed Racer
Speed Racer
Speed racer uses one of my "All in one" Stamp II controller boards and an HVW Technologies L298 DC motor driver board. This board is driven by a pair of my PWM chips and powered by an 800mah NiCd AA battery pack. The controller is powered by a 9V battery. This thing is FAST and really I need to have some kind of speed feedback for it to work well. The motor torque varies greatly with battery voltage and needs constant attention.
Killbot is my fully autonomous entry into a local competition called the Critter Crunch here in Denver and Colorado Springs, Colorado. Its controlled by my Stamp II Miniboard with the Stamp II SX chipset, one of my IRPD boards and one of my serial servo controller chips. It uses two hacked RC servos for wheel motors, a 12V battery pack to run the wheels, a 9V battery for the computer and pneumatics for the scoop. I use Lego system pneumatic cylinders to move the scoop and a blue Lego air tank for powering them. It can run the scoop <top secret> number of times before needing repumping. It uses two Makita 5 inch saw blades for wheels and has several edge and enemy detection sensors. Soon it will get the ability to see behind it! Here is the current (icky) source code for KillBot.
The Tick
The Tick
There isn't much to say about The Tick yet. It uses hacked RC servos for motors and one of my Stamp II Miniboards and IRPD boards for sensors and control. Soon it will get a compass and a video transmitter camera as well as a PIR sensor. This will eventually be my demonstration platform for display and fun. It is based on the SAM Robot chassis by Norland Research.
Hacked Cyber Spider
I got this Cyber Spider at Toys R Us for about $15. It was pretty cool as an IR controlled spider, but that just wasn't good enough! I took out the IR controlled stuff and put in a 16C84 with a pared down version of my IRPD board trimmed to fit. Click on the picture for the page describing the circuits, code and a couple of pictures.
Godzuki sumo
This is Godzuki. He's named that because I have a little sound chip on it that gives three Godzilla screams when activated! It consists of a Tamiya twin motor module set on the slowest speed, two of my IRPD modules, an HVW Technologies L298 dual H-bridge board and uses an OOPic controller for the brains. I have an IR based edge detector on all four corners that is made from Radio Shack parts. The whole thing fits into a 9cm x 10cm square and weighs in at just under 500 grams with the 6 cell NiCd AA pack.

All of the All-in-one and Stamp II Miniboards are based on Peter Anderson's "Homebrew Stamp II" kits. These give the functionality of the Parallax Stamp II at about half the price. They are NOT Stamp II's, they are the basic chips in DIP packages that need assembly into the proper circuit. For about $21.
