A group of participants performed a collaborative conveyer task that needs to transfer objects to designated positions by vehicles in a virtual space. All utterances were transcribed and questioning utterances were specified based on rising intonation patterns and content of the speech. Then we classified these utterances into four types: planning (ask whole transporting strategy in task), partner's (asking the movement and status of the partners), self (asking own movement and status), and other, and analyzed the changes of the frequency of these question types during 10 trials. We also constructed a collaboration levels and evaluated collaboration status for each completion of a box conveying. This collaboration level was determined by the number of people who collaborated to move one box during one trial. We investigated the relationship between strategy changes, collaboration levels, and question utterances. The results were that in a group that showed a strategy change, collaboration level was generally higher and more varied than the collaboration level observed in the group that showed no strategy change. In addition, in a group that showed a strategy change, question utterances about whole plan decreased but question utterances about the self status increased. However, in a group who showed no strategy change, all types of question utterances decreased. It was found that when a strategy change occurred, people tend to make more questions about self status to confirm the details of movement to complete the task. Collaboration level changes can be a good index to infer occurrences of strategy changes. © 2010 IEEE.

This paper gives an overview of the development of a novel biped walking machine. The robot is designed as an experimental system for studying biped locomotion based on torque controlled joints. As an underlying drive technology, the torque controlled joint units of the DLR-KUKA-Lightweight-Robot are employed. The relevant design choices for using this technology in a biped robot with integrated joint torque sensors are highlighted and some first experimental results using a conventional ZMP based control scheme are discussed.

Impedance and Admittance Control are two distinct implementations of the same control goal. It is well known that their stability and performance properties are complementary. In this paper, we present a hybrid system approach, which incorporates Impedance and Admittance Control as two extreme cases of one family of controllers. This approach allows to continuously switch and interpolate between Impedance and Admittance Control. We compare the basic stability and performance properties of the resulting controllers by means of an extensive case study of a one-dimensional system and present an experimental evaluation using the KUKA-DLR-lightweight arm.

Accurate and effective parameter identification is an important engineering task in high performance control system design. One emerging approach to effectively identify such nonlinear or dynamic unknown parameters is to use Particle Swarm Optimization (PSO) algorithm. Linear Permanent Magnet (LPM) motor is a high performance actuator employed in many applications that require direct linear motion without mechanical transmission for high acceleration and accurate positioning. Therefore, accurate motor parameters are necessary to effectively control the LPM motors. This paper proposes a simple PSO based method with chirp inputs to identify the LPM motor's parameters. The simulations and experiments are conducted to verify the results and determine the effectiveness of the proposed method.

Importance of developing human adaptive robots or systems is increasing these days. To accomplish it, we have to clarify features of human-human communication. In this study, we analyzed human speech while completing computerized collaborate task to clarify how humans speak in collaborative work. We extracted questioning speeches from conversations using CLAN, and classified them into four categories according to their content. We investigated whether the number and ratio of each type of questions changed over ten trials. The results indicate that leader role person is sensitive to task planning.

This research proposes a method to eliminate friction effect and reduced tracking error on CNC milling machines. A CNC milling machine has many connected mechanical components which have friction effects such as ball screws and rails. To control servo motors which are used to drive X-Y table in CNC milling machine, the conventional PID controller is widely used. In this research, Panasonic motor driver is set to the torque control mode. To compensate the friction effects, the friction feedforward compensation method is proposed. Moreover, to reduce the position tracking error, position feedforward controller is used. The simulation and implementation of position control in one axis of PID with Friction Feedforward Compensation and Position Feedforward Controller (FFC-PFC) are presented.

Volumetric mapping is essential for recognizing the 3D environment and consequentially for the decision making process for special-task mobile robots (such as stair climbing, inspection, or search and rescue). In this paper, we propose a fast surface detection algorithm based on point cloud data from a small pitch-actuated laser range finder mounted on a mobile manipulator arm. The developed algorithm is mainly composed of two steps: (i) gradient based classification; and (ii) Recursive Connected Component Labeling (RCCL) algorithm. The algorithm was experimentally validated. A complete segmentation of different planes in the environment was also successfully accomplished.
