摘要： A manipulator includes a manipulation body having a plurality of bar-shaped portions which intersect orthogonally with each other at one intersection point, and a plurality of detection bodies which detect a displacement of the manipulation body. The plural bar-shaped portions include a bar-shaped portion and another bar-shaped portion which intersect orthogonally with each other. The plural detection bodies include a first detection body which detects a displacement of one end side of the bar-shaped portion with respect to the intersection point, a second detection body which detects a displacement of the other end side of the bar-shaped portion with respect to the intersection point, and a third detection body which detects a displacement of one end side of the bar-shaped portion with respect to the intersection point.

摘要： In a spring body for a force transducer built into a force-transmitting part, a force-input section is provided for receiving a force, a force-output section for transmitting the force, and an elastic deformation body arranged therebetween which couples the force-output section to the force-input section such that the force received by the force-input section is transmitted to the force-output section. The elastic deformation body performs a predetermined elastic deformation movement caused by the force to be transmitted at at least one point. A coding sampling section is provided at the at least one point of the deformation body and which follows deformation movements of the at least one point.

摘要： A method is provided for determining a weight of a payload carried by a support structure of an agricultural utility vehicle via a hitch. The hitch includes at least one upper link and at least one lower link. The method includes determining the weight based on at least one of (1) an angle between the upper link and a vehicle horizontal, and (2) a holding force that arises at a connection between the upper link and the payload and is effective along the upper link.

摘要： Achieving high spatial resolution in contact sensing for robotic manipulation often comes at the price of increased complexity in fabrication and integration. One traditional approach is to fabricate a large number of taxels, each delivering an individual, isolated response to a stimulus. The proposed sensors include a continuous volume of soft material, e.g., a transparent polymer, and light emitting diodes configured to emit light into the transparent volume that can be received by photodetectors. The location and depth of indentations can be measured between all pairs of light emitting diodes and photodetectors in the set, and this rich signal set can contain the information needed to pinpoint contact location with high accuracy using regression algorithms.

摘要： Disclosed is a continuous measurement method for a wheel/rail vertical force. In a first unit measurement area, a second unit measurement area and a first-second compound measurement area formed by the first and second unit measurement areas, the method comprises: using measurement results of a first and a second shear force (Q1, Q2) measurement point and of one or more vertical support force (Nj) measurement points of the rail sleepers between the first and second shear force (Q1, Q2) measurement points to obtain a wheel/rail vertical force (F1) applied to the first unit measurement area; using measurement results of the second and a third shear force (Q2, Q3) measurement points and of one or more vertical support force (Nj) measurement points of the rail sleepers between the second and third shear force (Q2, Q3) measurement points to obtain a wheel/rail vertical force (F2) applied to the second unit measurement area; obtaining the wheel/rail vertical force applied to the first-second compound measurement area; and combining wheel/rail vertical forces applied by a wheelset to the first and second unit measurement areas and to the first-second compound measurement area to obtain a continuous wheel/rail vertical force of the wheelset. Further disclosed is a fully continuous ground measurement system for a wheel/rail vertical force.

摘要： A human-collaborative robot, by which the robot is unlikely to be accidentally operated despite the intention of the human, even if a relatively simple action pattern is determined as a command to the robot. When an external force by a human is applied to the robot, the force is detected by a force sensor. The robot is configured to be stopped when the detected external force exceeds a predetermined threshold. In order to restart the stopped motion of the robot, the human purposely applies the external force to the robot. When a judging section judges that the external force is applied to a specified portion the robot based on a predetermined action pattern, a commanding section commands the robot so that the robot performs a motion which is previously associated with the pattern.

摘要： A sensor including a layer having viscoelastic properties, the layer comprising a void, the void filled with a fluid; and optionally, a more rigid sensing element embedded within the layer. When a force is applied to a surface of the sensor, the shape of the void changes, causing the electrical resistance of the fluid in the void to change. When included, the more rigid sensing element can bear upon the void to cause the electrical resistance of the fluid in the void to change. A direction and intensity of the force can be determined by measuring the change of the electrical resistance of different voids positioned about the sensing element. The layer can be an elastomer, preferably silicone rubber. The fluid can be a conductive liquid, preferably Eutectic Gallium Indium. The sensing element can be plastic and can have a “Joystick” shape. The voids can take the form of channels or microchannels having a predefined pattern and/or shape.
