Abstract: A robot hand apparatus includes a first holder having a bendable first sucking surface that sucks an object using negative pressure; and a second holder having a bendable second sucking surface that sucks the object using negative pressure. The first holder and the second holder are arranged such that the first sucking surface opposes the second sucking surface. When the first holder and the second holder hold the object, in a state in which the first sucking surface is bent at a first position and the second sucking surface is bent at a second position, the object is sucked to a region of the first sucking surface between the first position and a distal end of the first holder, and the object is sucked to a region of the second sucking surface between the second position and a distal end of the second holder.

Abstract: An assist wear item is worn on a portion of a living body and has an inner surface brought into contact with the portion. The assist wear item includes assisting actuators, contact sensors, and a controller. Each assisting actuator is driven to expand and contract. The assisting actuators are linearly arranged along an expansion/contraction direction of a muscle at the portion. Each contact sensor detects a contact with an outer surface of the assist wear item. If the controller receives a detection result indicating a first contact from a first contact sensor among the contact sensors and receives a detection result indicating a second contact from a second contact sensor within a first time period after reception of the detection result indicating the first contact, the controller increases or decreases a driving power of expansion/contraction driving of an assisting actuator corresponding to the second contact sensor.
Abstract translation: 辅助磨损物品佩戴在生物体的一部分上并且具有与该部分接触的内表面。 辅助磨损物品包括辅助致动器，接触传感器和控制器。 每个辅助致动器被驱动以膨胀和收缩。 辅助致动器沿着该部分处的肌肉的伸缩方向线性地排列。 每个接触传感器检测与辅助磨损物品的外表面的接触。 如果控制器从接收传感器中的第一接触传感器接收到指示第一接触的检测结果，并且在接收到指示第一接触的检测结果之后的第一时间段内接收到来自第二接触传感器的指示第二接触的检测结果， 控制器增加或减少对应于第二接触传感器的辅助致动器的伸缩驱动的驱动力。

Abstract: An electric wheelchair includes a main frame; a driving wheel supported by the main frame; an electric motor disposed on the main frame to drive the driving wheel; a clutch that switches a power transmission path from the electric motor to the driving wheel between an engagement state and a disengagement state; and a clutch operation handle configured to be moved in a predetermined range in an up-down direction. The clutch operation handle is configured so that when the clutch operation handle is stopped at a lowest position of the predetermined range, the clutch is operated so as to be in one of the engagement state and the disengagement state, and when the clutch operation handle is stopped at a highest position of the predetermined range, the clutch is operated so as to be in the other state.

Abstract: A moving body that follows a preceding moving body includes a position calculator that identifies a position of the preceding moving body based on an output value from a sensor that acquires information around the moving body, a receiver that receives displacement information indicating a displacement amount of a position of the preceding moving body due to movement of the preceding moving body, and an operation controller that performs control to move the moving body based on an identified position of the preceding moving body and the displacement information in a state of losing sight in which the position calculator cannot identify a position of the preceding moving body.

Abstract: A mobile robot that autonomously travels includes a body that has a front surface, a driver that is disposed in the body and that drives travelling of the body, a base that includes a spring and that is connected to the body via the spring, and a distance measurer that is disposed at an upper part of the base. The base is connected to the body in such a way that the base is movable to be in a first state in which the laser range finder is located inside the body and a second state in which the laser range finder is located outside the body. The spring generates a force that pushes the base from a front surface of the body to an outside of the body.

Abstract: A robot hand apparatus includes a holder having a bendable sucking surface that sucks an object; a magnetic elastic body arranged at the holder and formed of an elastic material containing magnetic particles; and a magnetic-field generator that is arranged at the holder and applies a magnetic field to the magnetic elastic body to change a coefficient of elasticity of the magnetic elastic body. When the magnetic-field generator applies a magnetic field to the magnetic elastic body, a flexible portion and a hardened portion having a bigger coefficient of elasticity than that of the flexible portion are formed in the magnetic elastic body. When the holder holds the object, in a state in which the sucking surface is bent at a position corresponding to the flexible portion, a region of the sucking surface between the position and a distal end of the holder sucks the object.

Abstract: An actuator includes a displaceable portion, first to fourth artificial muscles, a pressure adjuster that changes a pressure of a fluid filled in the first and second artificial muscles, an open-close valve that allows a fluid to flow into or out of the third and fourth artificial muscles, and a controller that drives the pressure adjuster and controls the open-close valve. Each of the first to fourth artificial muscles includes a coiled elastic tube. In an outer circumferential surface of the tube, grooves are helically formed about an axis of the tube. The tube is filled with a fluid. In the first artificial muscle, a direction in which the tube is coiled is opposite to a direction in which the grooves extend helically. In each of the second to fourth artificial muscles, a direction in which the tube is coiled is the same as a direction in which the grooves extend helically.
