JarPod Alive!

My hexapod "JarPod" taking it's first steps, designed, aluminium components machined and anodised by my goodself. Basic design largely based upon Matt Denton's MSR-H01 hex.

In this video, the hex is having a bit of a tough time walking around on the flooring...the rubber feet will be replaced with silicone rubber feet soon to aid grip. Also, at around 33s I put the hex into XY-translation mode, yet it appears to be suffering from Parkinsons... Why?

It's called servo oscillation, and it's pretty much robot parkinson. Except this is because the servos do not have

- A: A high enough refresh rate

- B: Enough power.

or

- C: The servo's are dying.

My guess is probably B.

Actually, it turned out to be "none of the above" ;) The manner in which the software had been written, it wasn't possible to apply a rotation and translation simulaneously (as was the case in this vid)...A simple flag set in the software cured the prob... Which reminds me, I do need to get around to uploading a newer vid of JARp walking around :) Thanks for the feedback anyways.

lol..gimma a min!! I'm uploading a slightly better vid (and will prolly take this one down) of it walking around in on-road and off-road tripod gaits. Eventually the I'll fit a pan/tilt "head" with some sort of webcam affair running face/scene recognition software to help it's way around looking for people to take snaps of :)

But does it DO anything?! *lol*

[zippy172]

Yes, walk around! Check out my newer vids of it Mark...It's now able to do backflips!

That'd be neat. I'm making my own and programming it with Arduino, so I just scouring all the hexapod videos. If only I had access to a cnc, it'd make it a ton easier.
