Here's a video I made showing the latest version of RDAS. Check it out:

It was nice to take the robot out in the field.

One of the things you might notice in the vid is that I have to push down on the sides of the robot so it can move. The reason why is because the extension piece that the motors are attached to tends to flex, so when the motors are trying to push onto the ground, it ends up flexing. This means that the wheels don't have good contact.

In the next revision I'll be evaluating if making the extension piece stronger will help. If it doesn't, I'll add a similar locking mechanism to a folding table. It would extend from the inner structure to the motor panels.

There are also new diagrams up in the project details. These give a clearer overview of my idea. Please check them out if you have time!
