In the first step, a 1-DOF power assist robotic system (PARS) was developed for object manipulation with it, and the dynamics for human-robot co-manipulation of objects was derived reflecting human cognition (weight perception). Then, an admittance control scheme with position feedback and velocity controller was derived from the weight-perception-based dynamics. In a user study, human subjects lifted objects with the system. An evaluation scheme was developed to evaluate human-robot interaction (HRI) and co- manipulation performance. A reinforcement learning method was implemented to learn the admittance control parameters resulting in satisfactory HRI and manipulation performance. The results showed that inclusion of weight perception in the dynamics and the learning control were effective to produce satisfactory HRI and performance. In the second step, a novel variable admittance feedforward adaptive control algorithm was proposed, which helped further improve the HRI and manipulation performance. Then, effectiveness of the adaptive feedforward learning control method was validated using a multi-DOF PARS for manipulating heavy objects.

We present a design and functional prototype of a wearable technology for command andcontrol of a remotely-operated ground vehicle used for intelligence, surveillance, and reconnaissance missions. A novel interface using hand motions, gestures, and a hands-free display allows the operator to control the robot using standard military hand and arm signals. We leverage existing lightweight wearable sensing and feedback mechanisms to allow soldiers the ability to maintain situational awareness while providing instructions to their robotic squad members. This paper presents recent test results of the system and its sensors using the proposed feedback andcontrol mechanisms.

This paper presents RoSA, the robot System Assistant, a concept for intuitive human-machine-interaction based on speech, facial, and gesture recognition. The interaction modalities were found and reviewed through a preceding wizard-of-oz study showing high impact for speech and pointing gestures. The system's framework is based on the robot Operating System (ROS), allowing modularity and extendability. This contactless concept also includes ideas for multi-device and multi-user implementation, using different workstations.

There have been several attempts already made to control an industrial robot using hand gestures. The current work proposes a different methodology for controlling an industrial robot. Instead of having an external arrangement of controllers, the robot-Studio software which is compatible and intended for ABB robots, is maneuvered to achieve gesture control of robot by connecting it with python programming software. Here, a Python programming software with an OpenCV library is used to acquire coordinates of the hand gesture recognized with the help of Cascade Classifier technique. We have implemented Socket Programming between robotStudio software and Python software for transmitting those coordinates to the robot and thus accomplish a real time interface between them.

This paper firstly introduces the function and hardware components of the robot. Then the complex motion trajectory which must be implemented in small space is analyzed in accordance with the requirements of the control of archwire bending. Various communications methods that are used to set up a communication between the robot and the host control computer is studied as well as the principle and realization of the robotcontrolling method which is used to make a preparation for constituting the overall framework of control software. Finally, the procedure method of control software that is based on Visual C++6.0 is analyzed. The control software is used to control the archwire bending robot in remote mode.

In this paper, a wrist joint angle estimation model based on support vector regression(SVR) is established, which is optimized by combining the cuckoo algorithm with the steepest descent method. The sEMG signals were sampled from two forearm muscles. In order to shorten the model train time and improve the accuracy of the estimation model, a new technique combining cuckoo algorithm with the steepest descent optimization method is proposed to find the bestc and bestg of SVR in a short time. Experiments on a subject showed, the proposed method shows a good performance in both accuracy and timeliness. Then, in order to verify the estimation effectiveness and practicality of sEMG, the estimation angle was used to control a KUKA robot in real time, and obtaining a good experimental result. The method discussed in this paper can provide a valuable reference for the sEMG based control for rehabilitation robot systems.
