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.
What has six legs, 25 LEDs, a Microchip CPU, can be sewn into clothing, and even plugged into a Raspberry Pi? The answer, it turns out, is the CodeBug–a low cost computer board aimed at the educational market. These board were crowdfunded and are now available for general purchase. [Mike Redrobe] took one of the boards, connected a few servos and used the CodeBug’s Scratch-like language to create a small robot.
You can see the robot in the video below. Programs download via USB (the board looks like a USB drive). You can also send commands over USB to operate in tether mode, or you can directly plug the board into a Raspberry Pi.
The goals for the robot kit were to spark curiosity for electronics and programming, to be easy to assemble and program, to be scalable, and to be as easy on the wallet as possible. This was accomplished by using the familiar Arduino microcontroller on an intuitive platform. The robot uses an ultrasonic rangefinder to navigate as well, and can support a wide range of other sensors. The kit comes in at just under $50, making it a great option for an entry-level robot.
The project is currently seeking crowd funding and [Richard] is also seeking educators to get involved. Currently the only kits available are at fairs and other conventions but they should be able to start producing them in greater quantities in the future. The Arduino libraries are a work in progress but they are available on the project site, as well as several instructional videos and other information about the project.
The Arduino IDE only brings the ire of actual EEs and People Who Know Better™, but if you’re teaching robotics and programming to kids, you really don’t want something as simple as a text editor with a ‘compile’ button. For that educational feat, a graphical system would be much better suited. [Julián] has been working for months to build such a tool, and now miniBloq, the graphical programming tool for just about every dev board out there, has a new release.
The current version of miniBloq can be downloaded from the gits, with versions available for Windows and *nix. The IDE is written with wxWidgets, so this could also be easily ported to OS X.
