Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

Are there any concerns with using a power supply to power the motor drivers and motors over using a battery? Should I expect issues or will this function fine. This is a Senior Design project and I just want to be sure I have everthing covered. Thank you!
Also, a power supply powered by a generator will be used for the power source and the ROV will be controlled with analog inputs from the surface.
It comes with a 100 uf capacitor which, correct me if I'm wrong [...], is designed to handle current spikes when the motors start,
would you still suggest adding 10k uf capacitors across the terminals?
I now plan to use this motor driver: http://www.pololu.com/catalog/product/756It comes with a 100 uf capacitor which, correct me if I'm wrong (likely as I'm a Mechanical Engineer and this electronics stuff is new to me lol), is designed to handle current spikes when the motors start, would you still suggest adding 10k uf capacitors across the terminals?
[...] since I'm using analog control with 50' of ethernet line, what would be the best way to provide 5 volts to the potentiometers? Should I provide the 5 V from a source at the surface or from the 5 V pin on the Arduino aboard the ROV via a strand on the ethernet line?
The potentiometers are inputs to the Arduino board for speed and direction control of the thrusters and robot arm (servo driven). We plan to use the analog 3 axis joystick [...]
The tether will be an ethernet line not sure if that would change your answer,
could you point me in the right direction for digital control?
The Cat 5 line will only be used as a connection between the analog joystick and Arduino.
Will noise on ethernet line from the current in the power line be a significant concern? Also the pots in the joystick are 5kohm.
