I updated my Lego NXT holonomic platform a bit. The main changes revolved around the orientation of the motors so I could get true 360 degree movement.

As you can see the motors now orient in a circle around the robot.

I tried two different mounts of the motors. A high mount, that gave good ground clearance but had less stability and a low mount, that was more stable, but required all tires/feet to be on the outside of the robot. The video below shows the differences.

Here is an example of a lower motor mount with the feet on the outside.

Another shot of the motor mounting and the feet.

I also added some cross bracing for the motors to my original triangle platform base.

Here is the video:

Nice, you have REALLY improved you old one.
Does the vibrating give you less accurate results though?
Robolab 2.9
The vibrating does make navigation harder, but it reduces friction as the robot moves about so it is a bit of a trade off.
Is it faster than a regular monitor?
