A couple quick questions:
What are the advantages of using pneumatics vs. servos to shift the Dewault transmissions? Do the Dewaults shift optimally without slowing down or cutting power to the motors (however briefly)? Thanks in advance, Robinson |

Re: Shifting transmissions: servo or pneumatics?
our team suggest using a pneumatic shifter than a servo simply because the servo takes to much time to shift as for the pneumatic its a lot quicker
but most it depends on what your aiming for your robot design |

Re: Shifting transmissions: servo or pneumatics?
I don't believe you could utilize all 3 speeds on a DeWalt if you use pneumatics (as FIRST pneumatic pistons can only be extended or retracted, not halfway). For that reason, I would suggest using servos.

Re: Shifting transmissions: servo or pneumatics?
From years of rc car racing experience, go with pneumatics, servos strip easy.

Re: Shifting transmissions: servo or pneumatics?
i dont think the time delay is that big of a problem. its like 1/4 of a second of so for pneumatics and maybe 1/2-3/4 second for servos and servos in my oppinion are a lot easier to use.

Re: Shifting transmissions: servo or pneumatics?
But if the servo strips then you are stuck in a gear for the whole game.

What about shifting while driving quickly/pushing? Will the Dewaults hold up? Or should I quickly cut power to the motors in software (~1/40th of a second, not really enough to slow the robot) before I shift? Thanks again, Robinson |

But if I were to implement a shifter, I would use a servo, no question. Far more controllable, lighter (especially if no other pneumatics are used) and more flexible. Don |
