How it works

  • The Connect to button allows you to define on which robot you will send your program.
  • Dragging and dropping a box creates a ready-to-use copy of a predefined program.
  • The Play buttons has a 2-in-1 function: it uploads the program on the robot and starts its execution.
  • The execution automatically starts the box linked to the onStart input.
