SIE is researching on small bipedal robots to explore new possibilities for entertainment through robotics. To enable robots to perform dynamic movements such as running and jumping, it is necessary to not only increase the output power of the actuators but also to provide shock absorption capabilities. In this study, we developed a small series elastic actuator using a torsion coil spring as the elastic element and implemented it in a single-legged robot. The spring absorbs the impact upon landing and utilizes the stored elastic energy to enable efficient continuous jumping motions.
