Building a LEGO Candy Cane Catapult

How do you build a LEGO catapult that will send candy canes flying? “Okay, yes,” admits LEGO aficionado Jason Allemann, “it’s really more like a trebuchet, but ‘candy cane catapult’ has a certain ring to it, no? Regardless, this was a fun project which may or may not have resulted in many broken candy canes that needed to be eaten.”

The holiday-themed JK Brickworks video above shares each step of building this candy-hurtling machine with parts from the LEGO Mindstorms Robot Inventor set.

The model features a few interesting design elements. The hub itself and two of the motors are used as the counterweight for the throwing arm, which it is primed and released using a single motor and spring loaded trigger. The color sensor is used to detect when the launch button is pushed, and the feed system is gravity powered, using a reciprocating arm to release a single candy cane at a time onto the throwing arm.
