Had to share: The courier just dropped off this box of goodies:
Those who have been on the list a while might remember back in September 2003 when a small group of us met in the St Albans community centre I had a wee 3 servo perspex hexapod running off a Basic Stamp. At the time I was saying how I was going to do amazing things with a bigger one.
Well, its only taken me 11 years but I’ve finally put my money where my mouth is and ordered a 18servo alloy hexapod kit off ebay.
In the middle I’ve played around with a few different designs but never really finished anything. I have some single 3DOF legs in the junk box, a couple of 4DOF ones along with the mandatory collection of servos with stripped gears to show for my efforts.
At the moment its a pile of bits as you can see, but finished size will be about 500mm across with the legs fully extended. Should keep me off the streets for a while I’d say! :-)
Electronics plan at this stage is an arduino mega running the phoenix inverse kinematics engine. Servo power will be a couple of 10A switching regulators for the servos fed from a 3cell 1800maH Lipo. Probably a separate small 2cell lipo to run the micro, will see on that count although it’ll run tethered initially as I don’t have the ubecs yet, and even though the servos are metal geared I’ll just make smoke if I try to have it wandering around by itself before it’s debugged. :-)
I'll post random progress photos over the next 11 years as I try to make it walk!
Cheers, Chris H.
