cool! im going to post soon too an astromech droid. Some tips:
*connect sensors on the head.
*place the Ultrasonic sensor lower than the head, so that it can see low things.
*place the legs higher, on the highest end of the nxt, under the head.
*maybe you have use this tip, but use one 2x360 wheel (also called castor wheel) on the 3th leg. So it can turn good.
Succes with building!
@lama-mantis : Thank you for your tip, I'll do that :)
OOOOOH so the servo motors are vertical to operate the treads right? Dosen't that reverse the controlls?
Looks good for a start, but it definitely could use a lot more work. ;)
@Robogeek : the servo connected to treads directly, And I didn't get the mean with 'Dosen't that reverse the controlls?' :S What did you meaning for?
@mate called 'nxtstep101' :P
Thank you mate :) I am going to do a lot of work :)
Here is my second r2d2 droid!
It is driven by two nxt motors, and head turn by one nxt motor which is geared down.
It is still working in progress. Suggestions welcome!
Thank you :) please comment!
