Arthropods move low to the ground using their legs in a tripod fashion, which is inherently stable. Their skeleton provides local control over movement. But the secret to their success is their jointed legs, which act as struts and shock absorbers. At The University of California at Berkeley, Professor Robert Full studies arthropod locomotion to unlock the secrets of their success. Students see two different robots in action, each using jointed legs patterned after arthropods.
