Third Autonomous Run

Brainbot takes his third autonomous run, using wheel encoders and a 9-DOF IMU to do dead reckoning waypoint navigation (approximately 27 meters out, and then back again). I'm not using the laser scanner for obstacle avoidance, as you can see in this video, but Brainbot is fairly robust, and things that might stop a smaller/less capable robot can be driven right over with this chassis...

I like it. Custom parts no doubt. :)

Was the platform stabilised (I saw it rock near the start of the vid) or was that just a rock?

I tried something like that with linear acts in the corners of a platform supported in the middle, but results were less than satisfactory for either instruments or vid.

The platform is not stabilized, and you did see it rock. That is one of the issues with using a rock crawler chassis - it is less than ideal. Of course I didn't realize that when I chose that chassis, but I do now.

Does it use the GPS?

[JonHylands]

No, in this video it isn't using GPS. The GPS module I was using sporadically shut off, so I have since switched to using a different module.

Nice! what happened around 0:43
