The DrawBot is an Arduino based large scale plotter on wheels. This was just a proof of concept to see how well it would work.
Features include:
Bluetooth enabled so commands can be sent to it remotely- 3D printed chassis
- Omni-directional wheels
- Suspension on all wheels
- Arduino Uno with Adafruit motor shield
The suspension was needed to keep all 4 wheels firmly in contact with the ground because even the slightest uneven service caused slippage.
In the video it's powered by adaptor, but with a bit of effort to make it more power efficuent it could be completely stand-alone.
How it works:
- Convert an image to vector with Inkscape
- Convert the vector to CNC GCode with Inkscape
- Use a bluetooth terminal application like CoolTerm to send the code to the Bot
- sit back and watch it go
