Spiral Zipper

Spiral Zipper is a novel linear actuator developed in Modlab.  The fundamental concept is that a long thin strip of material is generally flexible along its length but stiff along its height.  If we pattern the upper and lower edges of the strip , winding this strip in a spiral will create a rigid load-carrying […]

Little Robots to move Big Things
Little Robots to move Big Things

The Little Robots to move Big Things project is motivated by the paradigm in modern robotics that most robots are incapable of manipulating objects that are even a small proportion of the robot’s mass. This project seeks to overturn this trend by using small robots to create large forces by leveraging the reaction forces created through interactions with fixed objects in the workspace.
