Hexapod Robot CNC Router

that thing is so awesome, it just felt humane of some kind. cute thing

just unbelieveable

Hi, teh hexapod doesn't know where it is on the paper, it just assumes once it is stood on it, the paper won't move.

this is a good work of desing

Watching plotting is ever so much cooler than seeing a piece of paper slide out of a printer, even if the graphics might not be as perfect. I saw the paper move as it walked away. How do you make sure it knows where it is on the paper (or in the case of a router, the part)? If it's feet are "sticky" enough and if it knew how to, it could grab the paper and the underlying surface and control the relationship between the two since it has lots of legs.

Awesome work. And yes, please give it a laser.

I would agree, sounds like you may have a bad cell, or dry joint.

At the battery. I'm really thinking its a badly manufactured battery, because I've never seen a voltage drop like this before either!

Are you measuring the voltage drop at the battery or the servo? You shouldn't get any drop by the battery, or at least very little!

Just out of curiousity, what is the voltage drop on the battery when the servos are running? My 6V 4200mAh NiMH drops to 5.5V when draining only 2A . . . But the manufacturer claims it can do 35A - I don't believe!

Power consumption isn't too bad, digital servos just tend to be noisy! I'm running the hexapod from a 4.8V 7500mAh NmHi pack.

nice! . . . and the loud hum of the digital servos sounds like power lifetime is a bit low, no?

Very very cool. Honestly though, you've made something that looks so sweet... it needs to do something other than draw. Give it a freakin laser for gods sake.

My hats Off! Very impressive. far more complex than simple xyz axis movements!

Wow, very impressive -- it must've been a lot of fun coming up with a translation from line drawing to leg movements!
