In lower mammals, locomotion seems to be mainly regulated by subcortical and spinal networks. On the contrary, recent evidence suggests that in humans the motor cortex is also significantly engaged during complex locomotion tasks. However, a detailed understanding of cortical contribution to locomotion is still lacking especially during stereotyped activities. Here, we show that cortical motor ...

In this paper we describe the design of a new bio-inspired amphibian robot with high environmental adaptability. The robot, called MiniTurtle-I, can transform terrestrial and aquatic locomotion configurations through a new variable topology mechanism (Leg-Flipper). Based on the modular design philosophy, four rotatory joint modules (Joints I–IV) constitute a Leg-Flipper module. Variable topolog...

Rao, Nikhil V. M.S.M.E, Purdue University, December 2013. Analysis of an Actuated Two Segment Leg Model of Locomotion. Major Professor: Dr. Justin E. Seipel, School of Mechanical Engineering. Research studies on dynamic models of legged locomotion have generally focused on telescoping-type leg models. Such telescoping spring loaded inverted pendulum (SLIP) models have been able to accurately pr...

Research on the biomechanics of animal and human locomotion provides insight into basic principles of locomotion and respective implications for construction and control. Nearly elastic operation of the leg is necessary to reproduce the basic dynamics in walking and running. Elastic leg operation can be modelled with a spring-mass model. This model can be used as a template with respect to both...

The development of functional legged robots has encountered its limits in human-made actuation technology. This paper describes research on the biomimetic design of legs for agile quadrupeds. A biomimetic leg concept that extracts key principles from horse legs which are responsible for the agile and powerful locomotion of these animals is presented. The proposed biomimetic leg model defines th...

Lower limb amputation significantly affects the quality of the leg amputee’s daily life. Recent advancements in embedded electronics and electromechanical actuators have propelled the recent development of powered artificial legs [1-3]. Usually, finite-state machine (FSM) is utilized in the design of powered prosthetic legs to control the knee joint impedance or knee position in each gait phase...

“The nurse is temporarily the consciousness of unconscious, love life suicidal, leg amputee, eyes newly blind, a means locomotion for newborn, knowledge and confidence young mother, voice those too weak to speak” (Virginia Henderson) [1].

The objective of this study was to identify claw lesions causing clinical lameness in lactating Holstein Frisian (HF) crossbred cows in dairy cattle. Seventy dairy farmers were interviewed at the monthly meetings of Progressive Dairy Farmers Association of Ludhiana, Punjab, India. Ten dairy farms were randomly selected as per probability proportional to size and a total of 450 lactating HF cros...

Every day new technology appears. In the field of legged robots, it is not otherwise. LIDAR vision, artificial intelligence, computing power and drives help to improve state robots. One unsolved problems still terrain navigation, such as locomotion in resistive terrain. To determine correct locomotion, research must be carried out. this paper, we compare two different situations, where a six-le...
