The Virtual Robotics Toolkit (VRT) is a robotics simulation software that allows you to design, build and program virtual LEGO Mindstorms creations, without the need for a physical robot.

Go beyond paper mats and household props!

The Virtual Robotics Toolkit comes equipped with several sample projects to get you started, a number of competition mats to hone your skills, and even provides the tools to change the physics engine itself. Have you ever wanted to see what would happen to your robot in the weightlessness of space? Now you can!

Never again disassemble something that you worked so hard on. The Virtual Robotics Toolkit lets you store your creations as files that live on your computer, making it easy to come back to a project at a later date.
