Arduino’s are easy, but they have very limited IO and don’t support much hardware off the bat. Great for beginners, but when your ready for the big boy league, the Axon is the way to go. A ton of IO, Uarts and ADC, all in a very small easy to use package. Does your project have a bunch of servos? Building a hexapod? You need the Axon. No shields required.

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.

While waiting for parts to come in for SAGAR, I decided I’d kill three birds with one stone. I wanted to adapt my Irobot command code to be compatible with Webbot’s Lib, I wanted to test Webbot’s new Project designer, and I wanted to try out a Force Field Obstacle Avoidance Algorithm. This is what I came up with.

It’s an Irobot Create, controlled by an Axon 2 running Webbot’s Lib, a Sharp IR and a standard servo. Theoretically, obstacles in front of the robot will ‘repel’ it while free space ‘attracts’ it. The closer and more directly in the way an obstacle is, the more it ‘repels’ it away.
