Motor controller control/feedback

[nuclearmistake]

Need the following:
An E-Stop button (with a state indication... green = estop off, red = estop on... and text)
When pressed, send the opposite of the last state reported by the robot.
from robot: /estopState std_msgs/Bool
to robot: /setEstop std_msgs/Bool

voltage display:
from robot: /Voltage std_msgs/Float32

I can work on both of those.

I assume that the /Voltage topic will report a value between 0-100, which
represents the remaining battery power.
Correct?

It is actually raw voltage ATM... For now, that's fine... if, after I've watched a few power cycles of these batteries' voltages, I can describe a neat conversion from that to a %, I'll let you know. Most lithium batteries' output voltage is fairly constant until they're nearly drained, then it dives. Without communicating with the battery directly, I don't think a "percentage" is feasible.
