PDXBot dates are set %G–%@ May 19 and 20 2007. Indoor events will likely be on Saturday, outdoor events will be on Sunday.
Annual membership renewals are due -- $12.
The current challenge is a simple maze. The robot must negotiate intersections and find the end-point of the maze. You may still try earlier challenges %G–%@ ’¡Èright angle challenge’¡É and ’¡ÈThird turn challenge’¡É. Monty Goodson demonstrated his line follower, and a good discussion of his robot design ensued.
Robomagellan from Open Source tools:
Ubuntu linux, Open Embedded, JAL, python, Mark-III, and NHLU2
Overall Strategy is to use a NSLU2 network-attached device for high-level processing, and use it to command a Mark-III board that commands the robot. Programming on the NSLU2 is written in Python. The programming on the Mark-III board is written in JAL.
The robot platform will have motor control, accelerometers, rotational sensors, proximity sensors, steering servos, USB camera, etc..
Challenges:
Finding all the OSS components and learning how to make them all work.
Finding a suitable embedded Linux computer.
Integrating binary Serial interface between Python and Mark-III
Building the NHLU2 embedded Linux + Python Image.
Writing the JAL and Python Program.
Debug.
Next Steps:
Finish up embedded python integration and debug
Integrate inertial navigation and compass
Build platform integrate drive and navigational primitives.
