This paper proposes a robot hand for a violin‐playing robot and introduces a newly developed robot finger. The proposed robot hand acts as the left hand of the violin‐playing robot system. The violin fingering plays an important role in determining the tone or sound when the violin is being played. Among the diverse types of violin fingering playing, it is not possible to produce vibrato with simple position control. Therefore, we newly designed a three‐axis load cell for force control, which is mounted at the end of the robot finger. Noise is calculated through an analysis of the resistance difference across the strain gauge attached to the proposed three‐axis load cell. In order to ensure the stability of the three‐axis load cell by analyzing the stress distribution, the strain generated in the load cell is also verified through a finite element analysis. A sound rating quality system previously developed by the authors is used to compare and analyze the sound quality of the fourth‐octave C‐note played by a human violinist and the proposed robot finger. 相似文献

Any service robot should possess some kind of human–robot interaction to communicate with users. In this paper we present a tour-guide robot able to recognize hand gestures and provide voice feedback. A user can communicate with the robot using hand movements, but also through virtual buttons which are shown in a augmented reality environment in the robot’s screen. Moreover, the user continuously receives feedback from the robot’s screen or by means of voice messages. The result is a robot that understands the users’ needs and which keeps them informed about what it senses, which increases the usefulness of our robot. Finally, to measure the quality in use, we have conducted two user studies, which we have used to reveal and correct the weakness of the robot. The guide robot was successfully tested in several real world environments. 相似文献

One of the key components of an ubiquitous robot (Ubibot) is the software robot (Sobot), which can communicate with embedded robot (Embot) and mobile robot (Mobot). Sobot is a virtual robot, which has the ability to move to any place or to connect to any device through a network without any spatial limitation. Embot has the capability to sense the surroundings and to interpret the context of the environment and can communicate with Mobot and Sobot. Mobot provides an integrated mobile services. To incorporate Sobot, Embot, and Mobot reliably as an Ubibot, a middle layer is needed to arbitrate different protocols among them. This paper focuses on incorporating Sobot and Mobot to overcome physical limitations of Sobot for physical behaviors in real situations. To implement the incorporation of them, the basic concept and structure of the middle layer are proposed. The effectiveness of the middle layer for Sobot and Mobot is demonstrated through real experiments. 相似文献

This paper presents a tracked robot equipped with the proposed crawler mechanism, in which a planetary gear reducer is employed as a transmission device and provides two outputs in different forms with only one actuator. A robot which contains two crawler modules can generate several configurations through cooperatively controlling the two actuators. This tracked robot, which uses two actuators to give four outputs, however could have less realizable postures than that where each output is provided by one actuator exactly. To figure out what postures can be generated by the introduced dual-crawler robot, quasi-static analysis of the robot has been conducted while taking the rolling resistance into consideration and its realizable postures have been obtained numerically. The posture transition of the robot is also discussed in this paper. Experiments are conducted to verify the quasi-static analysis for each configuration. 相似文献
