JAC is my first tracked robot that I am building. I have been looking for a long time for a large platform with strong rubber tracks. I found this rover at a flee market for $20.00 and knew this was it. As many of you have seen in my pass post a video of it running and run it does. The best part is it can climb stairs although I don't think that will be a function right now until I find out how to control the lift motors with an H-Bridge. I have had some great suggestions using an RC setup to make the motors act as servos but still trying to figure that one out. The first picture show the rover as it comes out of the box. The second is it with the top shell removed and the arm attached. I like this arm it is strong enough to grasp and pick up a full beer. Anyway more pictures will come as the progress continues. Thanks again to all those who had great suggestion. I love this forum.

I can't wait to see more. I love that base.
@Tymtravler, what are you using to carve the foam to get that smooth a finish (whenever I tried in the past it wasn't exactly a great finish)? That's something I will need to do, possibly on Jarvis and definitely on my biped.
@tymtravler your robot looks like a very cool design.
Sweet! Very nice work
AT my old work we used a hot wire to cut Styrofoam and then a knife with wax on it to carve it.
@Rich I use the white foam that you get at the craft store and some good construction glue, but don't use the green solid foam for like plant arrangements. As for sculpting the foam I use a four way wood rasp which has 2 sides, one is flat with a rough and a fine cut and the other side is rounded with the same cuts. This is for larger cutaways and then I use 100 grit sand paper to smooth out the rough cuts.
I hope to get one on ebay when it show up.
Any updates on this sweet bot?
