I'm a complete newbie to robotics, so please be kind and use small words. :)
I've just recently discovered Gumstix, makers of tiny little one-board computers that run Linux, and wondered about their applications to hobby robotics. In particular, there is a "robostix" version which is only $50 (or $40 without connection headers):
I'm wondering if anybody here has any thoughts about this approach. One concern I have is whether jumping on the I2C bandwagon is going to make for expensive robots -- it seems like all the I2C gadgets I can find are made by Devantech, and those guys aren't cheap.
Their dual motor driver is $102, for example; if I can't do better than that then I'd be better off buying an extra RCX brick for every three motors I want to control. It also seems to a bit over-engineered too, with RC inputs and so on; I wonder if there are cheaper I2C motor controllers elsewhere.
But enough from me... what do y'all think?
Thanks,
- Joe
