Dot and Dash are robots made by Wonder Workshop. Dot is a single ball-shaped robot that will create lights and sound but does not move. Dash is larger and has wheels to move, and also creates lights and sounds. 

You will need a tablet to control these robots. Grab a Kindle Fire or iPad and go to the Wonder app. 

Press the + button in the top right hand corner to connect to a Dash Robot. The program should start walking you through some instructions on how to code Dash and/or Dot. Once you complete enough tasks, you will unlock free play time, where you can control them like a remote control car! Have fun!
