This paper presents an approach to robot arm control based on exploiting the dynamical properties of an adaptive oscillator circuit coupled to the joints of an arm. The approach is implemented on a real robot arm, and swings pendulums at their natural frequencies, turns cranks and manipulates slinky toys. These actions are all achieved using the same architecture, without any modeling of the ar...

This paper describes a control scheme combining a mobile platform which is commanded at the velocity level with a position controlled robot arm. Based on separate controllers for both subsystems a method for force guidance is proposed which provides control of the tool location and of the posture of the mobile platform. Only a single force/torque sensor is used for this purpose. Also the slower...

To open up a highly expanded functionality in direct cooperation with humans regarding mobile service and assistance robotics applications, as well as new applications in the field of automation in industries, the new biologically inspired, lightweight and elastic robot arm “BioRob” offers a new kind of human machine interaction. The functional principle of the robot arm permits the system to a...

Using pliable materials for the construction of robot bodies presents new and interesting challenges for the robotics community. Within the EU project entitled STIFFness controllable Flexible & Learnable manipulator for surgical Operations (STIFF-FLOP), a bendable, segmented robot arm has been developed. The exterior of the arm is composed of a soft material (silicone), encasing an internal str...

We have described an adaptive signal processing method that allows fine graded control of a cursor in three-dimensions from cortical signals [1]. Here we describe application of the same signal processing method to direct cortical control of a robotic arm for a variety of tasks. Ou r subject w as extensiv ely traine d in controlling a computer cursor in a 3D virtual environment. We applied the ...

In this paper the problem of system integration and dynamic modeling of a hydraulically actuated manipulator with seven degrees of freedom, i.e. HydroLek HLK-7W is investigated. The arm is fitted on Multi-Arm mobile Robot System for Nuclear Decommissioning (MARS–ND) applications purposes. This is a step forward with respect to the previous works where only kinematics of the robot was taking int...

Cerebral palsy (CP) occurs in over 2 out of 1000 live births and can impair motor control and cognition. Our goal was to create a robotic rehabilitation environment that mimics real-life situations by allowing simultaneous exercise of upper and lower limbs. We chose to use the Lokomat as a gait robot and added a novel removable arm robot, called PASCAL (pediatric arm support robot for combined ...

Gesture based natural human-robot interaction paradigm has few physical requirements, and thus can be deployed in many restrictive and challenging environments. In this paper, we propose a robot vision based approach to recognizing intentional arm-pointing gestures of human for an object grasping application. To overcome the limitation of robot onboard vision quality and background cluttering i...

Dual-arm robots are expected to perform work in a dynamic environment. One of the most basic tasks that a dual-arm robot does is pick-and-place work. However, this work is more complicated when there are several objects in the robot’s workspace. Additionally, it is likely to take a long time to finish the work as the number of objects increases. Therefore, we propose a method using a combinatio...
