The desire to reproduce and expand the human senses drives innovations in sensor technology. Conversely, human-interface research aims to allow people to interact with machines as if they were natural objects in a cybernetic, human-oriented way. We wish to unite the two paradigms with a haptic sensor as versatile as the sense of touch and developed for a(More)
We propose a tactile sensor based on computer vision that measures a dense traction field, or a distribution of 3D force vectors over a 2D surface, which humans also effectively sense through a dense array of mechanoreceptors in the skin. The proposed "GelForce" tactile sensor has an elegant and organic design and can compute large and structurally rich(More)
Humans can perceive not only the magnitude but also the direction of force applied on the fingertip. When we grasp an object, the weight of it is felt through force that is parallel to the skin of the fingertip, which is how the object can be grasped without slipping. Focusing on this point, we have developed a tactile sensor that can measure a distribution(More)
It is believed that the use of haptic sensors to measure the magnitude, direction, and distribution of a force will enable a robotic hand to perform dexterous operations. Therefore, we develop a new type of finger-shaped haptic sensor using GelForce technology. GelForce is a vision-based sensor that can be used to measure the distribution of force vectors,(More)
It is expected that the use of haptic sensors to measure the magnitude, direction, and distribution of a force will enable a robotic hand to perform dexterous manipulations. Therefore, we have developed a new type of finger-shaped haptic sensor that can measure a three-dimensional force vector field over a contact surface. The sensor consists of a(More)
In this paper, a dynamic releasing method for high-speed biological cell manipulation is proposed. A compact parallel mechanism, used for grasping and releasing microob-jects, was utilized for generating controllable vibration to overcome the strong adhesion forces between the end effector and the manipulated object. To reach the required acceleration of(More)
Recently, manipulation and observation of the cells are actively conducted in order to analyze the biological phenomena. Since the micro hand is usually fixed to the work environment, grasping target point of the cell on the opposite side of the micro hand by using a micro hand is limited by narrow workspace. If we move the micro hand in vertical direction(More)
The paper describes a method of fault-tolerant adaptive gait generation based on CPG controller with interlimb coordination for multi-limbed working robot. Multi-limbed robot is expected to work in dangerous, complicated narrow spaces, where human workers cannot reach. However, if one of the limbs is broken in the dangerous/narrow working space, human(More)
The reliable manipulation of micro-objects has been a still difficult work in scientific and technical field due to scale effects. This paper presents two types of release methods, using local stream and inertia force generated by 3D high speed motion of an end effector, for releasing and accurate positioning of biological cells. Two-fingered microhand(More)
