Hey Guys,

It’s been a while since I posted an update on SAGAR, but here’s the latest.

I wanted her to go faster. My original motors would only do about 1.2 m/s tops. Well, with a little help from a friend, I found new motors that would bring up the top speed to well over 3 m/s. However, they require more current to reach that speed, more then my original controller could handle. So it had to be replaced.

The actually driver H-bridge  is a Ardumoto from SparkFun.
