Hey folks, I'm new to the forum and fairly recent to the bot building scene. I'm an engineering student at Oakland University. I'm on a team and for the class we have to build a stair climbing 'bot. The 'bot will use 4 AME 210 12v 88in-lb motors to drive each corner. The stall current for ta motor is 27.7A and no-load is 3A and a system voltage of 14v. We're using a mini-dragon for the computing power. So here's the question. Which h-bridge/motor-controller do you recommend? We're considering the Robot Power "Simple-H", the SyRen "25A Regen", the Polulu "18v15 Simple High Power" controller, or the Sabertooth "25 Dual 25A" driver. What do you think? I've had a lot of experience with the Victor series, but they seem like over-kill for our application.
Thanks.
Ps. I'll post some pics/descriptions of the projects I've been involved in here at OU soon.
