Raspberry Pi powers robot domino-setting record

What’s that to do with Electronics Weekly? Effectively, YouTuber Mark Rober customised, constructed and programmed an autonomous robotic known as Dominator, “Dom”, to put the 102,000 dominoes. (It took simply over 24 hours, if you're questioning, to make the Tremendous Mario mural.)

You'll be able to learn the piece written by our Know-how Editor, Steve Bush, here.

It’s each steered and pushed by way of omnidirectional wheels powered by ClearPath servos from Teknic of New York, which purchased the file try to Electronics Weekly’s consideration.

Mark writes:

“Talking of wheels, the entire robotic runs on 3 omnidirectional wheels which can be spaced at even intervals of 120 levels. Particular management of those wheels permits for the robotic to maneuver freely in any path (the flowery robotics time period for it is a ‘holonomic’ system), which is important for exactly aligning with the dominos when making ready to put the following tray. The motors are pushed by ClearPath motors that are tremendous correct and fairly highly effective for his or her measurement. The motors hook up with the wheels by way of a 1:4 belt drive which permits the wheels to offer sufficient torque to maneuver the robotic (it weights ~200 kilos). All the motors (drive motors and lifter motor) are powered by a pair of 24V 20AH LiPo batteries.”

As for the mind of the robotic, that’s a Raspberry Pi 4, which handles high-level communication, calculations, and determination making. The Pi is related – by way of a USB hub – to downward-facing IR cameras, the Marvelmind indoor GPS sensors, and the ClearCore motor controller.

This controller, says Mark, handles the decrease degree management for each the drive system and the tray lifter.

“It additionally handles the straightforward I/O such because the tray servo, handbook tray buttons, and tray optical endstop. All of that is powered from a 22.2V LiPo battery which is regulated all the way down to 5V for the units that want it.”

Spectacular stuff. Take a look at the video displaying Dom in motion!
