Low-Cost, Arduino-Compatible Drawing Robot

Bringing women into technical education at times seems to be an insurmountable challenge. As a counter, a small drawing robot created by [MakersBox] might help. The robot was used in a ChickTech workshop for teen girls.

The goals for the robot were to have an easy to build, easy to program robot that did something interesting, and was also low-cost so the workshop participants could take it home and continue to learn. These requirements led [MakersBox] to the Adafruit Pro Trinket 3V, stepper motors for accuracy, and a 3d printed chassis to allow for customization.

Another version of the Arduino should work without any problems and even possibly a Raspberry Pi, suggests [MakersBox]. With the latter’s more diverse programming environment opening up a lot of possibilities

Drawing robots like this for education are not new. [Seymour Papert] created one of the first turtle robots, seen at the left, in the 1980s. He even created the Logo programming language and adapted it for use with the turtle. An interesting similarity between [MakersBox’s] and the original turtle is the drawing pen is in the center of both.

Hat tip to our friends at Adafruit.

A rose, is a rose, is a rose, even if drawn by a robot, after the break.
