How to build the LEGO® BOOST M.T.R.4 rover

The M.T.R.4 is a rover like no other. It’s built to explore its surroundings and help you lift, move, and even toss things, should you ever have a need for that. 

You can build it by following the easy building instructions in the LEGO® BOOST Creative Toolbox App. It helps if you’re an engineer – no, just kidding! As long as you follow the prompts on the screen, you’re on track. 

As your little rover buddy starts to take form, you’ll learn how to make its grabber arm move up and down, how to pick up things, and how to turn your tablet into a remote control for the M.T.R.4! Drag and drop the action icons on the screen to create a chain of events for the rover to play out, and you can start your adventures.
