Well I'm bored and I need a break from my normal high altitude exploits after 2 weeks of intense balloon launching in Niger, West Africa. Also the plan is to get to know another side of gumstixs and electronics which can be then applied to Pegasus especially in the attempts to stabilise the payload to allow for stereopictures etc.
The plan is to spend as little money as possible using everything that is avaliable. Now this might be slightly unrealistic when compared to most normal people as I do have quite a considerable collection of junk from the Peg missions however my stock seriously lacks electronic parts so the plan is to minimise circuit building :-D
Well there isn't really one! First things first will be to connect the gumstix up to the 2 servos of the car itself and then we'll go from there...
Using the kernel driver from the ChRoMicro project I can produce 2 PWM channels which can go down seperate GPIOs off the I/O pads on the bottom of the waysmall. One channel will go to the steering servo and the other to servo that runs the mechanical speed controller. The user programs will require a bit of adaptation but it shouldn't be hard to get it moving on its own accord.
One of the problems is that while I can see how i'm going to link up the gumstix and the car after that i'm not sure. The plan (I think) is to have an autonomous car that at least will follow a route. It'll need some sensors though I'm not sure where they'll come from. Definitly GPS.
