Educational Robotics Kids for Classrooms & Virtual Program for at-home Learning. VEXcode VR lets you code a virtual robot using a block based coding environment powered by Scratch Blocks. VEXcode VR is based on VEXcode, the same programming environment used for VEX 123, GO, IQ and V5 robots. We all know that robots make Computer Science (CS) come to life with real world applications. Now STEM learning can continue while at home for students, teachers and mentors with no access to their VEX robots.
