Anyone know how many sizes of this there are? Ive been checking ebay and seen a few different ones. Im looking for a fairly large one
Upgrade to ARC Pro
Your robot can be more than a simple automated machine with the power of ARC Pro!
The u-command is what I used. It has the following configuration
2 servos for track movement
2 servos to lift or lower tracks
2 servos for each arm, in out and up down
2 servos for the neck
2 servos to control eye movement
2 servos for eyelids
It also has the follwing components
IR sensor for edge detection
ping sensor for object avoidance
led's to indicate battery level
photo sensor for light detection
camera in eye
I modified the V4 to bypass the base. This give far more room. I also used ubec's to limit power to those devices that need to be limited. This saved space. The speaker in the EZB v4 was loud enough for me without the base. I also built a power distribution panel to prevent from having to cut wires.
I power him off of 2 7.4v 2000mAh lipo batteries. These are run in parallel and I have run them 3 hours solid while programming movements and run them down to about 7.8 volts. This is a lot of movement. One is velcro'd on the bottom of the robot. The other is inside the robot. The entire robot is closed.
I say all of this to help you to understand that the U-Command is probably plenty large unless you want to do some other things beyond what I have done. You just have to make a few modifications and you will be good. If you are going for even more and money is no object, pickup the big boy and have fun. If I could have found one for a reasonable price, I would have.
@ D.cochran I saw the price on it. I was shocked. I could have a army of omnibots for that. No thanks! Have you ever had to remove the treads or replace them? Im watching one on ebay now 12" but he seems to be missing threads
