Lego Ziplining Robot Climbs For Claps

The internet has given us plenty of cool robotics projects, but we don’t think we’ve seen one zipline before. At least not until now.

This cool little ziplining robot is courtesy of the folks over at [Tart Robotics]. As they described it, the robot moves using a 4-bar linkage mechanism with the motor’s torque “transferred to the arm mechanisms through a pair of bevel gears and a worm drive.” Even cooler, the robot is activated by clapping. The faster you clap, the faster the robot moves. That’s sure to wow your friends at your next virtual hacker meetup.

They had to do a bit of custom 3D printing work to get a few of the Lego components to connect with their non-Lego off-the-shelf bits, so that took a bit of time. Specifically, they had some cheap, non-branded DC motors that they used that did not naturally mate with the Lego Technic components used to create the rest of the robot’s body. Nothing a few custom 3D printing jobs couldn’t solve.

It always amazes us what cool contraptions you can put together with a few Lego blocks. What’s your favorite Lego project?

  1. pedantic complaint: this a very cool project but THAT’S NOT A ZIPLINE, it’s just a rope (or a cord or string, if you think it’s too small to be a rope)

    A zipline, by definition, is on a slope and uses pulleys and gravity to quickly transport people or cargo to the bottom.

    What this robot does (hand-over-hand rope climbing) is arguably much cooler than that.
