A robotic care bed mainly comprises a bed body and a mobile body, the bed body comprises a stationary part and two rotatable sides that form an opening in the middle portion of the bed body to accommodate the mobile body, the mobile body can be automatically combined with or separated from the bed body by electromagnet devices, the mobile body has double plate high/low and turn over structure to perform the necessary high/low and turn over features, the mobile body can be automatically converted into a wheelchair that having features of auto armrest setup and auto charging, the two rotatable sides can be rotated sideward or upward to make rooms for the wheelchair to be set up and to move out or return to bed body opening easily, the mobile body also equipped with an auto bidet system.

Embodiments of the present disclosure include a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, and one or more pairs of arm assemblies. The arm assembly includes a wheel configured to move from a first spatial location when the wheel chair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A medical chair includes a base, a seat, and a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position. The chair further includes a first actuator for tilting the seat with respect to the base, a second actuator for lifting the seat with respect to the base, and a leg rest actuator adapted to move the leg rest. The chair also includes a controller adapted to control the first and second actuators to move the seat between a first position and a second position such that the seat is both lifted and tilted at the same time as the seat moves from the first position to the second position, and wherein the controller is adapted to control the leg rest actuator such that the leg rest maintains a substantially constant orientation with respect to the floor.

The present invention relates to an electric wheelchair having a voice recognition drive system comprising: a traveling apparatus main body unit which has a plurality of wheels in a lower end thereof; a seating unit which is installed in an upper end of the traveling apparatus main body unit so as to be able to be lifted; an auxiliary robot leg unit which is able to be inserted into and protrude from the traveling apparatus main body unit, and which includes multi-joint driven by an external force; and a voice recognition drive unit which extracts a preset command from an externally input voice, and which drives the plurality of wheels, lifts the seating unit, and drives the auxiliary robot leg unit.

A support assembly includes a fixable portion and a rotatable portion. The fixable portion is adapted to be fixedly mounted to a wheelchair and includes a shaft having a keyway formed therein that is supported by one or more mounts. The rotatable portion is received on the shaft and is in selective locked engagement therewith. The rotatable portion includes a bracket body with an opening into which the shaft of the fixable portion is received and a key member providing a key. The key member is supported by the bracket body and is movable in linear translation between an engaged position in which the key is engaged with the keyway to lock a rotational orientation of the bracket body relative to the shaft and a disengaged position in which the key is disengaged from the keyway permitting the rotatable portion to rotate relative to the fixable portion.

Disclosed is a mecanum wheel, including a mecanum wheel body and a drive device. A wheel axle hole is formed in the mecanum wheel body. The drive device is partially or completely arranged in the wheel axle hole. The axis of a connecting shaft of the drive device is collinear with a rotary shaft of the mecanum wheel body, and the mecanum wheel body rotates along with a housing of the drive device. Further disclosed are a mecanum wheel with a shock absorbing device, a chassis including at least one pair of mecanum wheels, and an assistant robot including a chassis.

A transport wheelchair comprises a frame with a chair base movably carried by a wheel base displaceable on a set of wheels. A seat, a backrest and a legrest are carried by the chair base of the frame. A pair of armrests is removably coupled with respect to the seat and each having an attached position on a lateral side of the seat and a removed position away from the seat. The pair of armrests is laterally displaceable and selectively positioned with respect to the seat. Each of the armrests have a lock to selectively lock and release the armrest with respect to the seat.

Embodiments of the present disclosure include a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, and one or more pairs of arm assemblies. The arm assembly includes a wheel configured to move from a first spatial location when the wheel chair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A medical chair includes a seat supported by a base and actuators adapted to both tilt and lift the seat with respect to the base. A controller controls the actuators to both lift and tilt the seat as the seat moves from the sitting position to the standing position. The movement from the sitting position to the standing position assists in the egress of an occupant from the chair, while the movement from the standing position to the sitting position assists in the ingress of an occupant to the chair. A backrest on the chair remains substantially vertically oriented during movement between the sitting and standing position so as to provide more comfort to the occupant during the sit-to-stand or stand-to-sit movement. The backrest also moves in a manner that generally keeps the occupant's torso vertically aligned with his or her hips during this movement.

Embodiments of the present disclosure include a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, and one or more pairs of arm assemblies. The arm assembly includes a wheel configured to move from a first spatial location when the wheel chair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters that can selectively engage the arm assembly dependent on the position of the arm assembly and surface conditions of ground and can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.
