The PlatypusBot is a TurtleBot3-inspired robot built from vacuum cleaner parts
Reading Time: 2 minutesWe all love the immense convenience provided by robot vacuum cleaners, but what happens when they get too old to function? Rather than throwing it away, Milos Rasic from element14 Presents wanted to extract the often-expensive components and repurpose them into an entirely new robot, inspired by the TurtleBot3: the PlatypusBot. Rasic…

Toss-launching drones is hard — this automatic launcher does it better
Reading Time: 2 minutesTypically, consumer drones take off from the ground or some other solid surface. But that isn’t very cinematic and toss launches — when the pilot throws the drone up into the air — are a lot more interesting to watch. Sadly, NickFPV isn’t very good at tossing his drone and that invites…

This perplexing robotic performer operates under the control of three different Arduino boards
Reading Time: 2 minutesEvery decade or two, humanity seems to develop a renewed interest in humanoid robots and their potential within our world. Because the practical applications are actually pretty limited (given the high cost), we inevitably begin to consider how those robots might function as entertainment. But Jon Hamilton did more than just wonder,…

Storing ephemeral micropoetry on RFID cards for bite-sized readings
Reading Time: 2 minutesMost people don’t consume poetry in the same way that they do novels. Instead of reading a book of poetry from cover-to-cover over the course of a few sessions, the majority of people seem to prefer enjoying poetry in occasional little chunks. And unlike the epic poems of Greek antiquity, those tend…
