Isoscel-Ease Drawing Robot is Mesmerizing

Isoscel Ease Drawing Robot

Drawing is difficult for a lot of people… So, why not build a robot to do it for you? [Darcy] had an idea for a rather unique drawing robot — he calls it the Isoscel-Ease.

Instead of using a boring XY gantry, a deltabot, or using a scissor linkage (actually that one is pretty cool!), [Darcy] decided to try harnessing of the power of triangle geometry! As you can probably guess, the linkage forms an isosceles triangle, hence the name. A pair of stepper motors increases and decreases the odd side of the triangle, allowing for a full range of continuous inky movement (there’s no pen actuator) over the page.

It’s a very cool little drawing robot, and it was completely designed in SketchUp — He has lots of photos of the build process and example drawings on his site — But don’t forget to stick around after the break to see a video of it in action!
