Energy-preserving control of a passive one-legged running robot
Fast and energy-efficient control is an increasingly important and attractive area of research in legged locomotion. In this paper, we present a new simple controller for a planar onelegged passive running robot having a springy leg and a compliant hip joint. The most distinctive advantage of the controller over previously proposed ones is it does not require any pre-planned trajectories nor ta...
متن کاملMechanical Differences in One-legged and Two-legged Hopping at Prefered Frequency
The dynamics of human running can be modeled as a simple spring-mass system (McMahon and Cheng, 1990; Blickhan 1989). This model is highly robust in its ability to describe the dynamics of bouncing gaits in animals with 2, 4, 6, or even 8 legs (Blickhan and Full, 1993; Cavagna, G.A. et al., 1977). Independent studies have shown that one-legged and two-legged hopping both exhibit linear relation...
متن کاملLegged Robot 16 . Legged Robots
In this chapter, we introduce legged robots. After introducing the history of legged robot research in Sect. 16.1, we start to discuss hopping robots and analyze a simple passive walker as a typical cycling walking robot in Sect. 16.2; the Poincaré map is one of the most important tools to analyze its dynamics and stability. In Sect. 16.3, the dynamics and control of general biped robots are di...
متن کاملSympathetic adaptations to one-legged training.
The purpose of the present study was to determine the effect of leg exercise training on sympathetic nerve responses at rest and during dynamic exercise. Six men were trained by using high-intensity interval and prolonged continuous one-legged cycling 4 day/wk, 40 min/day, for 6 wk. Heart rate, mean arterial pressure (MAP), and muscle sympathetic nerve activity (MSNA; peroneal nerve) were measu...
متن کاملStable control of a simulated one-legged running robot with hip and leg compliance
We present a control strategy for a simpliied model of a one-legged running robot which features compliant elements in series with hip and leg actuators. For this model, proper spring selection and initial conditions result in \passive dynamic" operation close to the desired motion, without any actuation. However, this motion is not stable. Our controller is based on online calculations of the ...
