This video showcases my custom designed Ultimate Machine (also known as a Useless Machine) built using the new LEGO Mindstorms EV3 kit. I call it the LuuMa EV3.

Watch part 2 here: https://youtu.be/g5y1pdPVDx8

It's a little bit more elaborate than the traditional ultimate machine, featuring 6 different responses for turning the switch off and 2 evasive maneuvers for trying to prevent the switch from being turned on in the first place.

Step by step instructions for building it can be found on my website at: http://jkbrickworks.com/luuma-ev3

The Mindstorms project file for running the program is also there. Instructions for connecting the ports can be found in the program file (open the content editor if it doesn't open automatically).

All the parts required to build the core are from set number 31313 LEGO Mindstorms EV3 kit.

I had a lot of fun with this one, especially programming the various responses. As always, let me know in the comments what you think, and if there are any other cool mechanical creations…
