Copper Robotics, an organization aiming to ship a strong open supply robotics framework written in Rust, has introduced a {Hardware} Connected on High (HAT) accent for the Raspberry Pi Zero household: the BalanceHAT controller..
“Some background: whereas engaged on numerous items of {hardware} to check Copper on them, I picked on goal a really under-powered platform just like the [Raspberry Pi] Zero to push the bounds of what the software program engine can do,” Copper Robotics founder Guillaume Binet explains. “Doing this I ended up with contraptions like this horrible rat nest… And determined to wash that up and construct a correct self contained [Raspberry Pi] HAT for it.”

The BalanceHAT, which is designed to match the footprint of a Raspberry Pi Zero, Zero W, or Zero 2 W and connects over the 40-pin general-purpose enter/output (GPIO) header, is a single-motor controller for compact robots, specializing in self-balancing tasks. It features a single DC motor output, managed by pulse-width modulation (PWM) indicators from the host Raspberry Pi, an enter for a directional Corridor-effect encoder, and an analog enter for a secondary sensor.
A USB Kind-C port with USB Energy Supply (PD) compatibility powers each the HAT and the Raspberry Pi to which it is hooked up, negotiation for as much as 60W of energy — which, in flip, can be utilized to drive any 12V DC motor. The analog enter, in the meantime, affords 12-bit precision and three megasamples per second (MS/s) sampling price, speaking with the host over a 48MHz SPI bus.

“That is all you’ll want to construct nifty little robots,” Binet claims of his creation, “like a self balancing rod, a self balancing one wheeler (we perceive why it’s known as balanceHAT by now), [and] numerous Roomba like automobiles.”
Extra data on the BalanceHAT is offered on the Copper web site; the Copper framework itself is offered on GitHub below the permissive Apache 2.0 license.
