Clearing Toys from the Swimming Pool – Overview

In this free video tutorial we set up the Challenge of using a LEGO MindStorms EV3 Robot to clear an imaginary swimming pool of toys left behind by children after they had departed. It includes a video demonstration of what we would like our Robot to do to push the toys to the edge of the pool, where our non-swimming helper can reach them.

This fun tutorial follows, and builds on, the “SUMO…” video tutorials, This tutorial uses the EV3-G program developed in the tutorial “Staying Inside the SUMO Ring”, so it would be preferable to complete that tutorial before enjoying the tutorial which you are now viewing.

Note: Comment on the Internet suggests that LEGO has “tuned” their color sensors to recognise the colors of their LEGO pieces. So when you go to a store to purchase a blue cardboard rectangle to act as a “swimming pool”, take a blue LEGO piece with you, and purchase the blue cardboard that most closely matches the blue of the LEGO piece. When testing, I have found some darker blue cardboard pieces register as “black”, and some light blue rectangles do not register as blue either. The shade of blue is important.

This tutorial video includes brief closed captions that may be translated into about 60+ languages using the inbuilt Google translator. Have fun!
