Kurt's conversion of CHR-3 to TH4-R with 2.1 beta source

Here is a quick and dirty video of TH4-R. Would have been longer, but camera battery ran out…

Kurt

That really looks nice! Yes too short! lol Well done Kurt!

That’s more like it! It looks pretty cool! 8)

You should post some body rotations too :wink:

Good work Kurt! Looks great!

I second Kåre, Body rotations are so cool with 4dof since it gives so much more freedom! I would love to see that! :smiley:

like it Kurt.
Ill third that. your just teasing us now. lol

Yep, I was just starting to zoom in, and the camera stopped recording, wrote everything to disk and turned itself off… I will try to make another one, but may do it with Arduino version. I may do it with the Mega with the Botboarduino Mega Shield prototype as to not have to tear the Botoboarduino prototypes out of the tri-track or Brat…

On a slightly different subject, I may also make a …CFG_ file for a 4DOF T-Hex, which should simply be taking parts of the CFG from the one I used for this and the other parts from the 3DOF T-Hex. That way someone could try it with a stock configuration.

Beautiful tile floor! But yeah, we’d like to see a little longer video…

Thanks,

Those are slate tiles that are on our outside covered patio.

I will try to do another video in the next day or so. Yesterday I swapped the BB2 board for an Arduino mega with .1 version of Botboarduino Mega Shield and debugged the 4 DOF code in my Arduino code base. I think I have that working pretty well now :smiley: Will probably make the next video with it, unless you would prefer to see it with the BAP. Not hard to change Back ( a couple of hex screws, PS2 wires, power, and SSC-32 wire…)

Kurt

Ok, this is a longer version, but the light was not great (i.e. the sun was out and contrast was not great, but…

This is running the Arduino version.

Kurt

That’s moving pretty good! Thanks for the update.

4DOF legs must make it a different spider then the Phoenix; heaver, shorter (?) legs.

It would be interesting to compare them side-by-side!

Alan KM6VV

I’m sure the Phoenix handles the non-tripod gaits much better as it’s lighter. I always click the left d-pad a couple times to slow it down a little on the larger bots. The Phoenix also walks better than the larger bots with the body closer to the floor, so on the larger bots I lift the body up a little more. I’ve noticed a little turning “stick” goes a long way, so I am careful not to overdo it. I use the R1 to lift the legs higher, but I never use R2 to increase the travel distance. It unwieldy that way. :smiley:

Where can i find this arduino 4dof thex code? Is it somewhere for download?

I ported the Phoenix code base to the Arduino and it does have the 4DOF code built in. I tested it awhile ago with the round body CHR that I had. Also others have tested it with converting the PhantomX to 4Dof. What I have not done is to setup and test the 4DOF configuration files for T-Hex. I have been doing 3DOF code for it. So you would probably need to update a configuration file for it. My current stuff is up on github
github\kurte in the Arduino_Phoenix_Parts project

I was the one who tested it with the PhantomX. Worked well. :slight_smile:
