B.E.C.K. stands for “Bunny Ears Clock Kit.” B.E.C.K. is a digital clock, driven by four motors. Three of the four motors move the clock hands: hour, minute and seconds; the fourth motor drives the Bunny Ears moving linkages. Similar to a cuckoo clock, B.E.C.K. flaps its ears once every hour and multiple times at noon and midnight!

Most clock mechanisms are driven with one power source, (spring, weight, or motor, etc.), and thus need more gears than the Lego Robot Inventor (51515) includes. B.E.C.K. utilizes the Scratch Code to simulate a gear driven clock mechanism. Using Mindstorm’s Block Code (Lego Scratch variant) and the Lego Virtual Remote Control from the Mindstorm app, the user can setup the correct time by moving the Remote Control’s arrows for the minute and hour hands, as well as the A.M. or P.M. light indicator on the Distance Sensor.

Enjoy!
