Tiny Micro Tug Robots Can Pull 1800 Times their Own Weight

Posted By ASC, Friday, June 5, 2015

Researchers at Stanford University have built a micro-robot that can pull 1800 times its own weight using smart adhesive technology. The team that developed this robot took advantage of the van der Waals force, the same force used by ants and geckos, to create a strong, directional adhesive.  The bottom of the robot has a surface of 100-micrometre flexible silicone wedges that can adhere to surfaces.  When the robot is upright, the wedges barely touch the ground and do not stick. When the robot presses the wedges to a surface, they adhere and the tiny robot is anchored in place and can drag loads many times it’s own weight. Actuators enable the robots to quickly between freely moving and adhered states. Learn more about this amazing robot and its directional adhesive and watch it move huge weights here.
