I am looking for all the negative feedback (constructive criticism)
I see no control circuits for motor brakes?
What if one of the fans fail -- would the robot be OK? If so, why are the fans there? If not, how would the robot know something's wrong?Same thing for each other necessary component -- how would you detect failure in order to achieve safe shutdown/self-disabling?
QuoteI see no control circuits for motor brakes?The control circuitry is embedded into the Sabertooth motor driver. I can control deceleration through software
Sylvestre, it is true you can deal with acc/dec of the motors with the sabertooth, but the sabertooth has no outputs formotor brakes.
move the relays to the power for the sabertooth, that way both motors are shut down.I'd keep them both wired in series, supplying power to the sabertooth, that way if oneof them fails the other would still remove power from the sabertooth.
Ok one problem. It is bad for the Sabertooth to cut power while in operation. That is straight from DimensionEngineering
