This paper focuses on the issue of tracking the trajectory of a flexible arm. The purpose is to ensure the flexible arm follows the desired path in the joint space. To achieve our objective, we have three problems to solve: modeling, control, and trajectory planning. As in the case of rigid robots, the EulerLagrange formulation remains valid with the exception of dividing the flexible arm into ...

Over the past few decades a considerable number of studies have been made on impact dynamics. Zheng and Hemami discussed a mathematical model of a robot that collides with an environment (Zheng & Hemami, 1985). When a robot arm fixed on the ground collides with a hard environment, the transition from the free space to constrained space may bring instability in the control system. Therefore, the...

Robots are gaining more attention in the neuroscientific community as means of verifying theoretical models of social skill development. In particular, humanoid robots which resemble dimensions of a child offer a controlled platform to simulate interactions between humans and infants. Such robots equipped with biologically inspired models of social and cognitive skill development might provide ...

The behaviors of the animals or embodied agents are characterized by the dynamic coupling between the brain, the body, and the environment. This implies that control, which is conventionally thought to be handled by the brain or a controller, can partially be outsourced to the physical body and the interaction with the environment. This idea has been demonstrated in a number of recently constru...

nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. psychological factors such as catastrophic thinking, symptoms of d...

Robot grasping is one of the most important abilities modern intelligent robots, especially industrial robots. However, existing robot arm’s grasp detection work highly dependent on their edge computing ability, and safety problems in process are not considered enough. In this paper, we propose a new robotic arm model with an edge-cloud collaboration method. With scheme multi-object multi-grasp...

Humanoid robots are fascinating from two points of view, firstly their construction and secondly because they lend life to inanimate objects. The combination of biology and robots leads to smoother and compliant movement which is more pleasant for us as people. Biologically inspired robots embody non-rigid movement which are made possible by special joints or actuators which give way and can bo...

Physical interactions between robots and humans are an integral part of many neurorobotic, neural prosthetic and rehabilitation robotics applications. It is generally acknowledged that such interactions can be enhanced by providing robots with advance knowledge of the intentions of human agents, e.g. their desired motor plans and goals in a given context. One potential source of these intention...

Many industrial applications are well suited to non-anthropomorphic pick and place robots. Robotworld is adept at performing vertical assembly operations, which may constitute 60% of all manufacturing operations. Furthermore, non-anthropomorphic robots can achieve higher accuracy than anthropomorphic (six degree of freedom) robots because they can be calibrated to higher precision. In this repo...

A major challenge in robotic design is enabling robots to immediately adapt to unexpected physical damage. However, conventional robots require considerable time (more than several tens of seconds) for adaptation because the process entails high computational costs. To overcome this problem, we focus on a brittle star-a primitive creature with expendable body parts. Brittle stars, most of which...
