Re: Can we use globe motors this year?

THIS year FIRST accepted the donation of four BB motors and got rid of many of the older ones. My insinuation is that should BB donate a pile of RS775s and CIMulators, based on the precident set this year, I argue that they would be tempted to get rid of the CIMs. It is not a logical fallacy since a precident has been set. A precident that was preceeded by the Denso motors replacing the previous window motors and keyang, the CIMs replacing the Drills etc. When FIRST is offered a better deal on KOP parts, they take it in favor of their previous components.

Ah the days of the 300W+ Bosch drill motors I forgot about the high torque servo! I wish I had one of those now...
The BaneBot motors will never replace the CIM motors in the KOP. While BaneBot motors may be capable of high power outputs under the right conditions, they are just not rugged enough to survive use in a typical FRC drive train without smoking. The CIM motor right now is probably the perfect mix of power output, ruggedness, adaptability, and overall cost for FRC drivetrain use.

The BaneBot motors likely replaced the older Globes, window motors, Van doors, etc because of one reason: all those older motors were at the end of their production runs, and the companies just donated/sold the remaining ones to FIRST. This is why is was nearly impossible to buy replacements for these motors anywhere; the only way to get more of these motors was to trade with another team. FIRST "got rid of" these older motors simply because they exhausted their donated stockpile, and could not get more from the donating companies. This is why I think the Denso window motor's days are numbered as well, as they have been unavailable for purchase for two years now.
