I recently came across an article by Roboteq named Robovia.
It aims to build a PC-driven basic robot using their Roboteq controller.
While I was trying to gather the nessesary(typo) parts, I came across
the price tag of their AX2550 controller (their motor controller)- $490 dollars. This was pretty out of my budget, and I tried to find alternatives: * Controlling a "Dual PWM Driver for OOPic" (from thebotshop) using I2C from my PC mainboard-- I wasn't sure if this can be accomplished without OOPic? * Controlling the motors using BrainStem (note: all of them are in slave mode ofcourse) or, plain and simple: * Spending$490 over AX2550.

Any suggestions?

I am sorry as I didn't notice that a Microcontroller forum exists.

The devices under $20 will work for small loads (<2A maybe), I believe the controller mentioned in the original post handles over 100A per channel. Have you considered building your own h-bridge? That controller has lots of features, but you may not need them all. #### ivancho ##### New Member Check out the prices for what you are comparing...... For$490 in one hand you have:

And for $20 on the other hand you have: So what type of motors and what you want to do with them must be what you have to look at. For a simple small 'bot you can create and use one of the H-drive controlllers that handle less than 2AMPS (Max)... if you want to do battlebot type of thing you are going to buy or create a more powerfull drives. With a$20 motor controller you control a more or less $50-$100 motor. With a $490 driver you control$500-\$1000 dollar motors. So it is all relative :lol:
