Hackaday Prize Entry: Room-Tracking Red Vines Flinger

[Vije Miller]’s Arduino Licorice Launcher is based on the simple and logical premise that one must always have a voice-activated Red Vines catapult in the workshop. When he calls out to the robot, it turns to aim at him and flings a piece of licorice at his head.

The chassis is CNCed out of quarter-inch MDF and the spring-loaded catapult arm is managed by two servos, one to tension the arm and one to secure it until it’s triggered.  Third and fourth servos aim the catapult and dispense another piece of licorice from the magazine. His robot adapts a radio homing technique [Vije] learned about from RoboWarner, which allows a robot to track a moving RF signal.

[Vije]’s first prototype uses an Arduino Uno connected to a serial port on a PC, but he hopes to acquire an MKR1000 WiFi module, which combines a Arduino Zero with WiFi. Already, this Red Vines launcher is a complete success; the marketing team at Red Vines sent him a huge pile of swag and free licorice for his efforts. You can check out [Vije]’s promo video of the project below.

        1. As long as you only hold the solder with the same hand you wipe your bottom with, and eat with the other hand, you will be fine. Really. (You read it on the interweb, so it must be true.)

    1. I’d have to disagree. I think it’s rather obvious that the picture in this article is of higher quality than the picture in the old one.

      That being said, I believe it’s possible they got a new camera.

          1. It’s almost as though they accidentally wrote 2 articles for the same hack, then went “crap.. uhh, delay one for a year?”

            And so it was. And all was well, until the veteran readers realized something was amiss.
