This summer I am hacking my old RL 500 Robomower and turning it into an autonomous robot using the EZ-B. I started the major hack today with the installation of a motor controller for the robot. The motor controller has two PWM inputs for speed of the motors and direction control for both. It does not match exactly the motor control board in the demo on the site, so I will need some community input. Also, I have mounted a Kinect and the EZ-B camera on the robot. Ideally, the ARC s/w could support the Kinect... (come on D.J. Sures!). I have the book making things see and I might run processing and an Arduino in addition to the EZ-Robot to do the Kinect functions, but the data interface would probably be through the EZ-B and the Arduino via I^2 C. Maybe the arduino/processing combo can tell the EZ Robot system some basic info about the surroundings to help in navigation. I am all open to suggestions and input on how to do this. I'd like to add arms too, but they will have to be light because I am using a tri-pod for the body. BTW - I am not using the mower to mow anymore, blades are removed, etc.

Look at this on eBay:
3v-36V Dual 15A H-Bridge DC Motor Driver 30A for Robot / Car Arduino Compatible

could you further explain
" It does not match exactly the motor control board in the demo on the site" please,
i think i might be able to help.
i think that the EZb is great for live input of information (RemoteControl) of your robot. The arduino would be awesome for some autonomous mapping. possibly having the KiNNEKt on a servo for continous rotation mapping.
I just got new batteries for the system this week. I fired up the system and drove the robot around for a few minutes before it stopped working . It turned out the battery fuse blew (30A automotive fuse). I then checked the bridge. The input impedance is 0 ohms across the positive and ground power input connection. It appears the bridge is damaged. Thats what i love about Robotics, you take a few steps forward and then some back... but you got to keep on moving forward! Can you measure the resistance across your power input of the bridge (with at least one of the power leads lifted). This is the red and black wires in my photo. I'd like to know what it should read if I attempt a board level repair.
I got the sabertooth V2 and installed it on the robot tonight. Great advice. I don't yet really understand the values I used in the setup (found in another post), but it seems to work fine.
Here is the robot with the Sabertooth installed....
Here are my settings....

I'm glad the Sabertooth H bridge suggestion worked out for you. Dimension Engineering is well known for a quality product in a battle bot community and it looks like that translates to reliability in personal robotics too. I'm about to install a 2 x 12 model that just replaced their previous 2 x10 that they discontinued.
I have not messed with this robot in a long time. Now that we have the interface with the Kinect, I might look at it again. The robot is so powerful due to the gear ratio that you have to be careful to make sure you have a good e-stop!
