Visual Robot Features


  • The Visual Robot is a large working-envelope—590x350x120mm (23”x13.5”x4.75”)—leadscrew-driven cartesian-form 3-axis robot. It is the base element in a desktop manufacturing workstation architecture.
  • Its fixed-bed design allows multiple gantries to be put into service and run either independently or—with appropriate software—in cooperation with each other.
  • The design accommodates parts-presentation and tool-presentation devices to be placed in the space peripheral to the robot to begin to approach a fully automated manufacturing workstation.
  • The connecting parts, carriages for the axes, and end-effector platforms (EEPs) are all able to be 3D printed on a small 3D-printer—135x115x100mm (5½”x 4½”x4”).
  • The working height (Z-axis) is easily changed to provide greater stiffness or a larger working envelope with small changes to the gantry design.
  • Top-mount or bottom-mount choices can be made for the Z-axis motor.
  • Commonly used NEMA17 or more powerful NEMA23 stepper motors can be used for the ‘X’ and ‘Y’ axes.
  • Stiffness and precision are obtained using metal-to-metal contact of the rods, shafts and bearings on the ‘X’ and ‘Y’ axes.
  • Easily-reached, easily-used thumb-wheels provide bed-leveling on each of the machine’s four corners.
  • Control is by open-source hardware—Arduino Mega 2560/RAMPS, Megatronics, Printrboard, etc., and open-source software.
  • It was designed such that it could be built using easily available parts and built with a minimal set of tools.
  • With its glass bed, all parts are easily visible.
  • Full, detailed documentation on post-processing, assembly, and getting started with the electronics are provided.
