Simple object detection & avoidance. Testbed for tracked locomotion
- Actuators / output devices: 2 geared motors
- Control method: autonomous
- CPU: arduino 328
- Power source: one 9V battery for MCU, 6xAA for motors
- Programming language: C++
- Sensors / input devices: Ping on a sensor
- Target environment: indoors for now
July 24, 2009 Update:
Upgraded to use the new Pololu chassis plates.
This is my second bot. This one uses a RP5 tracked chassis that I bought from Pololu. It also uses Pololu's Qik2s9v1 serial motor controller. Currently the only sensor is a Parallax Ping attached to a servo for scanning. I plan on adding some Sharp IR's for close in detection and an optional line-following kit.
I made an Arduino library for the motor controller. It can be downloaded from: http://code.google.com/p/qik2s9v1arduino/

Living up to his name
Man ths guy is not to be messed with, he is a bot who knows where he want to go.....
The base unit looks well balanced and the turning (when it wants) is smooth too, full marks.
What is the verdict on the Motor controller .......

Very nice looking machine.

Problems? None. Learning experiences, plenty of those...
The biggest that I'm still dealing with is that one motor needs more power than the other to drive straight. I'll probably put encoders on the gears to help.
The other issue is the "stuck in a corner" problem that I'm still working on a good algorithm for.
