I made another scrap robot. Here are the pictures. She is made from parts of the Sunshine Robot, parts from the Omni-bot, and parts from the RAD robot, and an Electrical box. She is sort of a Frankenstein.
This is what I have so far.
I turned her on and connected to my desktop because I need another hub router for the usb ports.
I also haven't got any sensors on her yet. I have got only one sensor. But, I am hoping to make some progress soon.
I just slapped her together and tried to make a functional robot. The voice rec. and generation is working on the desktop soon to be transferred over the the W3 tablet.
that's about my progress.

If Rich doesn't answer your question there are many others here that have the answer.
I have a red and black wire and a Grey and White wire going to ports 15,16,17,18.
If I roll the robot on the carpet, it generates voltage to the EZB 3. Weird.
The solution in Melvin was to change to 4 ports which do not go high when powered on, I do not know which I found in the end since I've replaced the V3 for a V4 now.
The other option may be to use speed control. If the PWM to the speed control pins isn't set the H-Bridge wont move even if some of the In ports are high.
Spinning a motor will generate current, it is the dynamo effect, you are basically generating electricity (like a dynamo on a bicycle). Some batteries can be harmed by doing this as can some controllers. To avoid this you can include diodes however on small robots it's generally not necessary.
One thing I thought of is that I am using ONLY the signal wires, not grounds or middle wires. Could this be the problem?
I am moving on to another problem. I will post it as a question.
Thanks!
