No Robot, No Problem! Robot Virtual Worlds is a high-end simulation environment that enables students, without robots, to learn programming.
Research has shown that learning to program in the RVW is more efficient than learning to program using physical robots. RVW simulates popular real world VEX®, LEGO®, and TETRIX® robots in 3D environments while using the same language, ROBOTC, to program both virtual and physical robots. The RVW environment is perfect for home, classroom, and competition environments!
