Let's Make Robots!

Need some help with a few components.

Hey guys!

Im gonna start up on a RC tracked robot in a while, but im still at bit lost on what motors and controller i should use.

I have read about the Sabertooth2x25 and it seems like it's easy to use. I've found it to around 100$ which I think is quiet expencive. Is there any alternative that is easy to use?

I was thinking about using it with thies two motors with the following specs:

Power Rating:33W
Body Diameter:40mm
Rotational Speed Max:2100rpm
Torque Max:600mN-m
External Height:103mm
SVHC:No SVHC (15-Dec-2010)
External Diameter:63mm
No Load Speed:2100rpm
Power Consumption:4.8W
Supply Voltage Max:24V

Will this setup be usefull or do I need to change anything?

That L298N is only a chip right? If I use that one I need to solder the rest of the CPU on my own, or am I wrong?

@ Bajdi

Your right, it would be a bit of overkill with a 2x25A motor controller.


I have found a sabertooth dual 5A R/C 6-18V CPU, what I like about it is that it is just plug and play.

With two 12V batteries coupled in series this would work right?

I see.

I only found the chip when i googled it. Gonna try to search a little more.
