Hello all,
I'm trying to construct a rover to make its way around a household environment
and avoid obstacles reliably. I'm experimenting with several chassis designs
to find one to my liking. (Okay, so I build one design, try it for five
minutes, then take it apart and build another one. Such is LEGO.) Anybody
have a design that they're particularly happy with?
I managed to get hold of two Dacta rotation sensors so that I can keep track
of linear and rotary motion. I've worked out a few pointers that I keep in
mind as I try a new design and I'm trying to include as many in each design as
I can:
1) The rover should have a wide wheel base to make accurate turns
2) It should preferably have a low center of gravity
3) It should have room somewhere on it to mount a variant of Leo's
differential transmission to interface with the rotation sensors
I've posted an LDraw file of one of my rover designs on
http://www.lugnet.com/cad/dat/models/?n=210 if anyone's interested. Don't
feel obligated to post an entire design on here like I did; suggestions or
ideas of any sort would be welcome.
