Robo Crab


When I found out we were paying $200 every few weeks to replace the mechanical robot in one of our exhibits, I knew there had to be a better way.  I worked with volunteer Paul Stankiewicz to create a durable, low-maintenance, and affordable replacement.  The Robo Crab uses an over-sized motor, linear guide rail, and pivots with bushings and shoulder screws.

Materials cost around $200, and thanks to Paul’s generosity, it only took a little bit of my labor to manage the project.
