MiniBot Actuator Products


We have developed a new family of minimally equipped linear motion actuators.  These products fulfill the need for low cost single axis precision motion actuators that can easily be combined to form multi-axis platforms.   Most of these products find homes in life science equipment and lab automation equipment.  Each unit is provided complete with stepper motor.  Since we make all components in house we can easily modify each axis travel length or sensor arrangement to match your application requirements.

Designed for Compact Spaces and Low Cost.

All hardware (i.e., miniature recirculating ball linear guides, stepper motor, shaft coupling, ball or lead screw, and machined parts, etc.) are seamlessly integrated into the unit, allowing us to achieve a very compact size.   Developed for applications where low cost is a driving factor.  Below are the specifications.
