ATtiny84 3-servo hexapod

Avoids obstacles

Similar to the Pololu 3-servo hexapod, except I made my own PCB, built my own IR sensor system, and wrote my own code including hardware Timer1/interrupt assisted servo pulse control.

I would be one of those fans. I figured I'd be able to get 4 servos working across the tiny family but shelved the project some time ago. I was aiming at using an 8-bit timer though, so this looks promising.

So I take it you have made a library that will work on ATtinys that is still in development stages? I'm interested in trying it out (soon as my ATtiny84A arrives anyway!)


 Could you send me the code(if you used C++) and the instructions to build?

yes it's generally a bad idea! Now anyone can get at it *SPAMS*

This is great, what I like about it is it's not really perfect and controlled, it sort of flails around a bit. Adds to the creep factor a lot!

Reminds me of a harvest man that touched it's leg on a RCA cable that was in use. Because the cable was live the harvest man went all weird, one leg got wrapped around the cable and the other legs started scrabbling as it tryed to pull the stuck leg away. I had to unplug the cable to let it escape...

*Stops ranting*

Surely you could use only 2 servos? One for the middle left / right legs as you have it, and then one for all other legs? Or do you need the 2 outer legs on each side independant to turn? I am thinking of making this, it's really cool...
