This is my current crop of robots. Move the mouse over one of the pictures to get a brief synopsis of the robot. To be honest I have more fun building them, designing circuits, and trying out new ideas rather than actually using them or competing with them. I have also been fiddling with RF telemetry links, the tabs above will take you to the RF projects I used for the robots, The 433Mhz one was the first, I only use the 2.4Ghz tranceiver now. The local robotics group, O.R.E. is a good place for new people in the Ottawa area to start out. The group is very casual, attendance and activity vary between meeting but there is usually something going on. Do bring your kids, they like robots too. TAZ the fearless (above) was based on a robot controller board that we developed as a group activity.
Bot91: with Real Time Smarts This is my current effort. An experiment with a newish Zilog 8bit controller, the ez80F91 and an RTOS they developed and tuned for the chip. I am happy with both and will be using them for other projects. The robot uses simple skid steer drive, the motors have intergal encoders, there are IR sensors around the platform, and an ultrasonic sensor on a turret (servo driven) in the front. It also has a 2.4 Ghz RF tranceiver and was my first use of the new Lithium Polymer battery technology. I can highly recommend them an excellent power source. I also made a motor controller for it with current monitoring to protect the motors and batteries.
TAZ the Fearless ( the clueless? ) This is TAZ my mini-sumo robot, he’s not too clever though ... needs some ground sensors to make sure he stays in the ring (something for a rainy day). He is based on the IgORE2 robot controller we developed at O.R.E. (pictured below). I added a 433Mhz RF telemetry link to him that communicates via I2C bus. He has an IR sensor in the front and when he sees his opponent he will lunge forward and try to push him out of the ring.
At the left is the IgORE2 robot controller board we developed at O.R.E. (a group effort). It is based on the PIC18F452.
Rover: 4WD with Quadra-Steer This is a nice platform I am still working on (shelved temporarily). It has 4 wheel drive, all four wheels turn to steer. It can turn very sharply indeed. It can crab walk too which makes following walls quite easy as it can go sideways a bit without turning. Unfortunately 4 motors requires a lot of current. I originally had 4 kilos of lead acid batteries in it. Problem! The total weight overloaded the steering servos, I will try again with Lithium Polymer batteries. I also made a 4 channel motor controller for it with independant current sensing and auto-shut down.
Robie the Talking Robot ( the wise cracking robot ) While my daughter and I were watching Robot Wars she asked me if I could make a robot for her. So I did. It was the first one I made, using the venerable PIC16F877, an ancient speech processor, and an IR sensor mounted on a servo to avoid obstacles. If it came up to an obstacle it would stop, make some silly quip then change direction and move along. It was quite a hit, she loved it.
