I am looking for some real world feedback on teams experiences using a 6 cim drive train with a 2 speed transmission designed for both low speed (4-5 ft/sec) and high speed (say 14ft/sec).

If your robot got in an extended pushing / blocking match with other 6 cim robots for a good part of a match...

- Would you be at risk of blowing the breaker ? If so, how often did you blow your breaker last year. Did you replace the breaker one or more times last year. Have you implemented any software protection (reduce power after X seconds) or hardware (fan) to defend against that ?

- how warm or hot would the following be by the end of the match
- the battery
- the terminals on the battery
- the contacts of the battery connector
- the breaker, its terminals etc

- do you guys do anything to cool the cims (fans, aerosol can cooling for example)

I have heard of a team that replaced all the 14 gauge cim wires with 10g wire. Did you guys do anything like that ?

If the cim motors are stalled in a pushing match (and apparently drawing close to 100amps each), does anyone know for certain if the 40amp breakers trip at all (and reset seconds later) reducing some of the potentially 600 amp+ current off the main breaker. Maybe not if the 40 amp CIM breaker is overloaded 2.5 times (100amps / 40amps) versus 4.8 times for the main breaker (600/125).

What was your teams experience ? Thanks
