"Good" ESC on theory,
come with Zero Reverse Delay, and a 5A 6V regulator.
most important it has a Built-in Li-Poly Cutoff Protection at 6V :D
claim to have peak 400A drive and 200A brake...
just hope it works with my PIC18F6722... hmm ... :D

Crawler DC Motor
they are primary use in RC world Crawler vehicles. But i guess it is good enough for my Sumo Robot.
RPM: 3350 fwd, 3300 Rev
Turn: 130T
Dimension: 56mm Length, 36mm Dia
Shaft length: 11mm
Team Atlas Rock Climber Series (AT7-153)
No load Amp: 0.45A
Stall Torque: my guess is about ~150mNm
Terminal Resistance: 1.1~1.2ohm
Weight: 165~170g
M3 bolt at 25mm Dia

Conecting AX-12 to Arduino
Method 1:
Recommended circuity by Robotis. AX-12 is a half duplex uart system, the direction port pin is used to set transmission or receiving mode.
Method 2:
The diode helps to transfer incoming/outgoing signal to AX-12, taking the job of the direction port pin. Do not try this circuit if you daisy chain more then 2 AX-12 to Arduino. Arduino TX can not sink enough current to fan out the signals to several AX-12. This design is only good for prototyping.
