Description
An inexpensive, multi-purpose, extensible robot designed to provide tight integration with MyRobotLab. Simple and easy starting robot for the beginner, yet extensible to provide access to complex and advanced functionality in MyRobotLab, such as neural networks, speech recognition, finite state machines, and machine vision. Can cradle a phone as a method to deploy a much more powerful bot.

Pro
They are fairly cheap and have standard mounting holes. They are also muti-use (could be hacked to be dumb gearmotor or continuous rotation).
There is tons of existing hardware for them such as servo horns (to mount wheels on) and metal gears.
Con
They must be manually hacked by either the user or by us.

My initial thought is not to have an integrated H-bridge & rely on continuous rotation servos. I think motors can be controlled more accurately
Rotational Servo vs Motor - (I believe rotational servo - with no additional circuitry - "stopping/centering" can be done in software
If we use Lipo or Lithium ion batteries - is there a special Maxim chip to use ? And if so, I assume if the customer uses regular batteries and plugs it in "bad things" can happen - So if we are to use LiPoly batteries - There has to be an Danger warning not to use regular alkaline or nicad and plug it in to the usb ??
