We’ve always had a soft spot for omni rotates and the bots that move around reasonably bumpily on them. Likewise, CNC writes plotters are always a welcome spate in our gratuity course. But a CNC plotter applying omni motors is new, and the results are amazingly good.

Built from the bottom of a spring-form baking go,[ lingib ]’ s plotter is simplicity itself. Four steppers turn the omni pedals while a pastime servo makes and lowers the write. The controller is an Uno with a Bluetooth module for smartphone control. Moving wheel gyrations into X- and Y-axis flows was not exactly inconsequential, and the video below shows the results. Words are somewhat wobbly, and it’s clear that the plotter isn’t affecting the coordinates very precisely. But given the moderately compliant nature of the omni wheels, we’re surprised[ lingib] came solutions as good as these, and we salute the effort.

[ lingib] reports the most expensive part of this $100 develop was the omni pedals themselves. We guess laser-cut MDF omni wheels could increase the expenditure, or even Mecanum wheels from bent metal and grove. We’re not sure either will help with the accuracy, though.
