Many industrial robot arms are operated in industry, and some robotic applications in the industry, such as a pulling-out of products made by die casting, require the flexible motion excited by an external force. Here, the flexible motion means that the robot arm moves passively according to the external force. Industrial robot arms, however, are difficult to be moved by the external force beca...
A biped humanoid robot is prone to fall when walking or operating in a complex environment, and forward fall is one of the most common falling cases. This study focuses on the forward fall issue and presents an “Arm Flexible Landing Strategy” for safe falling. First, the forward falling motion is analyzed from an energy variation perspective of the robot system, and a method to choose best-fit ...
Uncertainties are the main reasons of deterioration of contour control of industrial articulated robot arm. In this paper, a high-precision contour control method was proposed to overcome some main uncertainties, such as torque saturation, system delay dynamics, interference between robot links, friction, and so on. Firstly, each considered factor of uncertainties was introduced briefly. Then p...
A mobile manipulation system often involves combining more than one robot together, typically a manipulator arm and a mobile base. To implement a force and motion control with dynamic compensation, a torque-controlled system is necessary. However, a torque-controlled robot is not always available. In fact, most commercially available mobile bases are velocity-controlled. This paper presents a m...
BACKGROUND Electromechanical and robot-assisted arm training devices are used in rehabilitation and might help to improve arm function after stroke. OBJECTIVES To assess the effectiveness of electromechanical and robot-assisted arm training for improving activities of daily living and arm function and motor strength of patients after stroke, and the acceptability and safety of the therapy. ...
This paper describes the development of a chess-playing robot called MarineBlue. This robot consists of three components: a computer vision component to recognize chess board situations, a chess engine component to compute new moves and a robot control component to execute these moves by means of a robot arm. In the paper, we focus on the algorithms that have been used to implement the computer...
This paper describes the implementation of reex action for the arm of the humanoid robot Cog [5]. A set of biologically inspired postural primitives are used to create the arm motion. The primitives are combined in di erent ways to achieve reaching with grasping and withdrawal reexes, allowing the arm to interact safely with both objects and people. This paper describes the re exes, the biologi...
Robotic manipulators are becoming a very common tool in modern industries and research laboratories. In order to successfully execute a given task a control software is necessary that sends and tracks appropriate orders to the robot arm. This paper presents the design principles of a general software framework capable to control any robot arm with any set of sensors. A possible implementation o...
In traditional teleoperation systems, the operator is saddled with two distinct tasks: 1) move the robot arm to its desired position, and 2) avoid obstacles that can obstruct the robot arm manipulator. To accomplish these tasks, an area of current teleoperation research is involved with providing the operator with as much input information about the task site as possible using, for example, ste...
