We love Raspberry Pi-powered robots however the Pico microcontroller, together with its RP2040 processor, has completely modified the sport. Pi tasks preserve getting smaller which leads us to Dot, the smallest Pi-powered robotic we’ve ever seen, created by maker Kaisar, also referred to as Roboticbits over at Twitter.
Introducing Dot.. a stamp dimension @Raspberry_Pi #RP2040 robotic.. the smallest on the earth! Makes a correct use of the @pimoroni #Tiny2040!#raspberrypi #robotic #robotics #make pic.twitter.com/rnYghWY6NJNovember 11, 2021
This robotic is smaller than the Raspberry Pi Pico module and, based on Kaisar, is roughly the scale of a stamp. It’s constructed utilizing Pimoroni’s Tiny2040 board, an ultra-small module that includes the RP2040 processor.
Dot is able to locomotion, utilizing two 3V geared DC motors. These motors are immediately linked to the Tiny240 by way of GPIO, not one thing we suggest because the motors can pull extra present than the GPIO can present. This venture is on the heels of one other small RP2040 robotic known as Pica, additionally created by Kaisar, which makes use of a modified Raspberry Pi Pico together with three motors as a substitute of two. These motors are managed by way of a DRV8833 motor controller
The unit receives energy from a 70mAh LiPo battery, making it completely cellular. To get issues transferring, Kaisar opted to program Dot utilizing CircuitPython. Nonetheless, plans are within the works to implement new code sooner or later utilizing C++.
