SimplySim has released an application that allows you to control either a simulated LEGO® NXT Tribot in a rich 3D environment or a real Tribot. It includes several sensors and a "claw". Some sample services are provided to demonstrate how to control the Tribot. You can also write your own services to run in this enviroment and control the Tribot.
As a Microsoft RDS partner, SimplySim has been involved in the creation of the simulation environments for the RoboChamps competitions and also developed the environments that ship with RDS 2008.
