Searching to capitalize on his familiarity with the Raspberry Pi, [Sebastian Zen Tatum] made the decision to put the diminutive Pi Zero at the coronary heart of his “antweight” combating robot, $hmoney. While it seems like there had been a few bumps in the road early on, the tuxedoed bot took household awards from the new Houston Mayhem 2021 competitiveness, proving the calendar year of Linux on the battle bot is genuinely on us.
In contrast to applying conventional interest-grade RC components, [Sebastian] suggests employing the Pi represented a sizeable expense cost savings. With Python and
evdev, he was equipped to choose input from a commercial Bluetooth recreation controller and translate it into instructions for the GPIO-linked motor controllers. For youthful competition primarily, this a lot more common interface can be found as an benefit around the vintage RC transmitter.
A L298N board handles the two N20 gear motors that present locomotion, when a Tarot TL300G ESC is responsible for spinning up the brushless motor attached to the “bow tie” spinner in the front. Insert in a Turnigy 500mAh 3S battery pack, and you have bought a compact and uncomplicated electronics offer to nestle into the robot’s 3D printed chassis.
In a Reddit thread about $hmoney, [Sebastian] goes around some of the lessons his team has realized from competing with their 1 pound Linux bot. An extremely ambitious armor style price tag them big at an celebration in Oklahoma, but a tweaked chassis ended up creating them a great deal much more competitive.
There was also a disappointing reduction that the team thinks was thanks to someone in the viewers attempting to pair their telephone with the bot’s Pi Zero for the duration of the heat of fight, knocking out controls and leaving them lifeless in the h2o. Ideally some improved computer software can patch that vulnerability in advance of their upcoming bout, primarily considering that everybody that reads Hackaday now is aware about it…
Though battles amongst these tiny-scale bots could possibly not have the same fireplace and fury of the televised matches, they’re an fantastic way to get the subsequent era of hackers and engineers fired up about setting up their possess hardware. We want [Sebastian] and $hmoney the finest of luck, and glimpse ahead to listening to far more of their war stories in the long run.
