BEST (Berkeley Emergent Space Tensegrities) Robotics

UC Berkeley doctoral students working on the tensegrity robotic research are: Andrew (Drew) Sabelhaus and Kyunam Kim. Five MEng students – Justino Calangi (Advanced Controls, ME), Yangxin Chen (Product Design, ME), Eric Cheng-yu Hong (Visual Computing Graphics, EECS), Yuejia (Margaret) Liu (Computational Manufacturing, ME) and Dizhou Lu (Product Design, ME) are working on the project by designing, building the mechanical components and developing a tensegrity kit for simulation and testing of actuation and control strategies. Deaho Moon is an undergraduate researcher who has been working on the mechanical testing and drop tests.

Research with Vytas SunSpiral and Adrian Agogino from the Intelligent Systems Division of the NASA Ames Research Center on a revolutionary soft robotics concept that integrates biomimetics and tensegrity structures. Tensegrity robots are composed of purely tensile and compressive components (cables and rods). We are exploring co-robot applications (where humans and robots work as partners) since they are unlikely to harm their environment or human users. The application areas we are pursuing include space exploration, home health care and search & rescue.

The simulated images (above) and animation (below left) are for the Super Ball Bots application envisioned for space applications where they could deployed and bounce to a landing before moving and exploring the surface. The image above right is of the UC Berkeley BEST Lab rapid prototyping tensegrity robot using linear actuators.

See video of NASA collaborators Adrian Agogino and Vytas SunSpiral explain the structural advantages of tensegrity robots in this article and video (below, right): NASA's Squishable 'Super Ball Bot' Could Explore Titan, IEEE Spectrum, December 2013.

Also see Kyunam Kim's simulation of the Super Bot robot using a lumped mass model of six struts.
