My endavours into robotics is currently only on a theoretical level. I will in the near future hopefully start to build my very own design for an all-terrain wheeled or tracked robot.
I'm thinking about a four wheeled/four motored thingy with articulated chassis. My first eureka was to measure the angular difference between the front and back chassis halfes and by that discover the steering drift. But then I realized that I would probably not be able to have an active steering for the articulation. But still, the angular measurement idea is perhaps not so stupid if I could find the correct sensor to make it work.
I've also been thinking about wheels or tracks. What are the opinioin against tracks? WHat are the opinion against wheels?
Any ideas from you more experienced people?
Purpose and requirements of my robot:
- Speed doesn't matter, It may be slow I don't mind
- terrain capabilites, I would like it to be able to roam the most difficult terrain (read newly plowed ground...)
- To be a platform for perhaps a video camera to track my cats just to see what they are up to
- Wake me up in the morning with some freshly brewed coffey (just kidding)
- As cheap as possible
- Small but not to small to not be able to roam the grounds
I'm looking forward to some good input!
