Just a blog for the OscarMobile build.
When Oddbot left Australia for his robot building job in China, I was lucky enough to score his collection that he couldn't take along with him. Included in this collection was the makings of a kickarse robot, named boozebot. Now after a couple of years, my wife and I have a son, and in a couple of years he's going to need a way to get around (walkings OK and all, but not much fun). So I'm using the base of OB's robot to make the OscarMobile:
The base is driven by two scooter motors from here
Speed controller also from here
As the motors are 24V, two sealed lead acid batteries will be the main power. Controlling the OscarMobile will be a picaxe 28x1, using levers as controls:
Next to each lever will be a speed display, these displays have red/green leds driven by a 5451 driver, with an 08M providing the data. The main 28X1 will send the lever position to the 08M via serial with no error checking (ran out of memory on the 08).
