Hi all,
I'm planning use roboteq motor driver for 24V brushed DC motor but i can't be sure that it's true or wrong. You know, roboteq controller is too expensive and i don't want to spend money in vain. Have you any experience this controller? Are they compatible with Arduino?
I also think, pololu Roboclaw driver. Pololu - RoboClaw 2x60A Motor Controller (V5) i don't know is it enough for wheelchair. Because, i already have used Pololu VNH5019 and it is not enough. (synchronicity and noice problems etc.)
I have a friend using a Roboteq controller for a wheelchair she is building. They came recommended
to her from other users, and the fact they list police/military robots on the list of applications for the
controller should tell you something.
You also need to ask yourself is 60A maximum enough?
If not - they have other offerings in the brushed-dc controller arena - up to 120A (per motor in a dual-motor config) and up to 300A for a single motor.
If you needed something larger, they could probably custom build it for you - just bring the $$$$, of course...
Part of our "thing", when we're not refurbishing chairs, is to take old chairs and parts (that can't be donated) and fab weird and fun things with them. We have a few radio-controlled machines - in those, we have mainly used Vantec controllers:
They are pretty battle-hardened; at one time (maybe even now?) they were the "go-to" controller for robot combat enthusiasts. The controllers aren't as "polished" as Roboteq's offerings, but they will do the job out-of-the-box.
I should note, though, that older versions of the Vantec controllers don't like the Servo library - the pulse output from the library isn't quite right, and a bit of mucking with the source code to change it to something the controller will take is needed - but I think all of that is fixed on their current offerings.
