A magnetic sensing approach for determining a positioning characteristic of a soft robotic actuator. A magnetic field or a change in magnetic field of a magnetic member may be measured as it undergoes concurrent displacement with a soft actuator. Additionally, an example rolling robotic wheel is illustrated. The robotic wheel may utilize magnetic sensing as described herein.

A housing for accommodating a section of a robot arm used in hygienic application and method for manufacturing the housing. The housing includes a housing body made of a material suitable for contacting product in the hygienic application, and a connector made of a second material having a higher strength than the first material. The housing body has an extension portion configured to accommodate the section of the robot arm, and a connection bore located at an end of the extension portion. The connector has an outer surface, wherein the housing body is connected on at least one portion of the outer surface of the connector to couple the connector onto an inner surface of the connection bore.

The present disclosure aims to provide a gear, a worm gear, and a robot, which have a low dimensional change rate due to thermal expansion and water absorption and have excellent durability and dimensional accuracy under high-temperature and high-humidity conditions even when the gear is composed of a resin. The present disclosure provides a gear having a first toothed portion provided on the outer circumference thereof. The gear contains a polyarylene sulfide resin as a constituent component. The polyarylene sulfide resin has a melt viscosity (V6) of 50 to 4,000 Pa.Math.s.

A robot joint control that eliminates backlash and utilizes Polymer (EAP) muscle.

An articulable mechanism includes a first link, a second link, and a joint structure coupling the first and second links to each other. The joint structure is configured to enable articulation of the first and second link relative to each other. A first pair of guide channels is defined by and extends through the first link. A second pair of guide channels is defined by and extends through the second link. A lining overlays one or more of at least a portion of the joint structure, the first guide channels, or the second guide channels. A pair of actuation elements extends respectively through the first guide channels, past the joint structure, and through the second guide channels. The lining provides an interior guide surface along at least part of a path of the actuation elements extending through the first and second guide channels and past the joint structure.

A medical instrument includes an elongate shaft having a base at a proximal end of the elongate shaft. A robotic system can robotically articulate the elongate shaft by transferring drive outputs from a manipulator to drive inputs of the base. A working channel tool assembly can provide robotic and manual control of a medical tool insertable into a working channel formed as a lumen in the elongate shaft. The working channel tool assembly can couple to the base and the combination can be operated as a single unit, which may be attachable on an end effector. The working channel tool assembly can include a chassis, retainer(s), shuttle(s), latch, spool(s), any other components that are designed to provide structural support and organization for one another when assembled. The working channel tool assembly reduces use of fasteners and adhesives through various structural feature on each of the components.

An arm body for a robotic arm includes a first tubular body made of plastic material, including a first tubular portion including a first axial opening and a second tubular portion the first tubular body being substantially closed except the first axial opening and the second axial opening. A first connecting portion is provided at the first tubular portion and includes a first mounting surface configured to be connected to a first component constituting a robot; and a second connecting portion provided at the second tubular portion and including a second mounting surface configured to be connected a second component constituting the robot.

Sealing arrangement including a sealing element arranged to seal a gap between a proximal member and a distal member, the sealing element including a sealing material configured to withstand a temperature of at least 100 C.; and a heating element arranged to heat the sealing material to at least 70 C. An industrial robot including at least one sealing arrangement and a method for sterilizing a sealing element are also provided.

A lightweight, under-actuated, compliant, quadrupedal robot employing twisted beams as legs, actuated by controllable one-directional vibration force to achieve diverse maneuvering modes. Adjusting the actuator's shaking frequency and direction, the robot can execute various maneuvers such as forward movement, lateral movement, and turning via the coupled, resonant response of the legs. The quadrupedal robot includes a body plate having a shape defining at least four corners; four legs, each leg coupled to one of the at least four corners of the body plate; and a dual-motor actuator coupled to the body plate. The body plate is rigid, and each leg includes a twisted beam formed of a flexible polymeric material.
