The Energy Amplification Characteristic Research of a Multimodal Actuator
International Journal of Advanced Robotic Systems, 2016 A multimodal actuator is proposed to fulfil the different walking patterns of a power-assisted knee exoskeleton. With this actuator, the exoskeleton leg can realize several modes of operation, including series elastic actuation, stiff position control ...

Non-Overshooting Force Control of Series Elastic Actuators
Solid State Phenomena, 2010 Whenever mechanical devices are used to interact with the environment, accurate control of the forces occurring at the interaction surfaces arises as an important challenge. Traditionally, force controlled systems utilize stiff force sensors in the feedback loop to measure and regulate the interaction forces.

Energy-based Safety in Series Elastic Actuation
2020 IEEE International Conference on Robotics and Automation (ICRA), 2020 This work presents the concept of energy-based safety for series-elastic actuation. Generic actuation passivity and safety is treated, defining several energy storage and power flow properties related to passivity. Safe behaviour is not guaranteed by passivity, but can be guaranteed by energy and power limits that adapt the nominal behaviour of an ...
