Ants are cool, but robots ants with mandibles are really cool. The site has several videos of the robot in action that you might want to check out. You are going to need a really big magnifying glass to burn this one!
The Biologically-Inspired Legged Locomotion Ant (BILL-Ant) is an 18-DOF hexapod with six passive DOF feet for force sensing, a 3-DOF neck and actuated mandibles with force sensing pincer plates (28-DOF total). The robot uses force sensors in the feet and pincers to actively comply with its environment and respond to external perturbations.
