The MagPi, Issue 53

The MagPi Issue 53Inside this month’s MagPi Magazine – the first issue to feature a cover-mounted DVD, boasting a bootable copy of the new Debian+Pixel Linux distribution for readers to try – you’ll find my review of a rather special little gadget: the Mirobot v2 programmable robot.

I’ve played with educational robots before, but the Mirobot caught my eye the minute I saw inventor Ben Pirt demonstrating it at the Maker Faire UK earlier this year. With a chassis made entirely from laser-cut MDF, the Mirobot is an impressive package: Ben has designed it so that every component nestles in holes cut out from the MDF sheets themselves, making for an extremely compact box which pops nicely through your letterbox and leaving almost zero waste once assembled.

The Mirobot is designed primarily for use as a turtle, and includes a mount for a pen so it can draw on suitable surfaces. Where it differs from most rival designs is that it can be programmed entirely through a browser: an on-board web server, running on the popular ESP8266 microcontroller, can work as a standalone hotspot with simple Scratch-inspired drag-and-drop programming interface or connect to your home Wi-Fi and allow access to additional languages, a point-and-click interface, and even a set of buttons for direct remote control.

With the exception of the Scratch language, which relies on Adobe Flash Player, everything works an absolute treat on the Raspberry Pi, but the Mirobot isn’t limited to this: it can be programmed from any modern web-connected device, from a laptop to a smartphone, or for more advanced users interfaced with via a well-documented application programming interface (API) from the language of your choice. Assembly is quick and easy, requiring absolutely no tools, and while aligning the pen and motors is a little trickier that’s a one-off job.
