摘要： A tracked climbing vehicle containing a compliant suspension apparatus to prescribe the distribution of forces on the adhering members in the tracked climbing machine. The compliant suspension apparatus is configured to negotiate irregularities in a climbing surface without the vehicle tracks losing full surface contact and adhesion by distributing the loads from the climbing machine chassis to the adhering traction members in a specific prescribed fashion. The apparatus thus avoids exceeding the allowable force in any adhering traction member and significantly improves the performance of the climbing machine.

摘要： A patient support apparatus for traversing objects supported on ground surfaces. The patient support apparatus comprises a patient support deck, and a base to support the patient support deck from the ground surface. At pair of caster wheel assemblies spaced from each other are coupled to the base for pivoting movement about respective pivot axes cooperating to define a reference plane. A frame guard coupled to the base defines first and second ramp surfaces each disposed at an angle relative to the reference plane. The first ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in a first direction. The second ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in an opposite, second direction.

摘要： A robot has a robot body on a frame structure, the robot body having at least one enclosed space to hold at least one delivery item. At least one sensing device detects objects along a direction of motion of said robot. The robot has six wheels, where at least two wheels on a side of the frame are connected to each other. The axis of rotation of each wheel is substantially fixed with respect to the robot during forward, rearward, and turning motion of the robot. During transition, via a substantially vertical obstacle, from a first substantially horizontally surface to a second substantially horizontally surface higher than the first substantially horizontally surface, one of the connected wheels causes an upward or a downward force to be applied to the other connected wheel.

摘要： A tracked mobility device includes a pair of track drives having a rear weight-bearing wheel assembly, a center weight-bearing wheel assembly, a forward weight-bearing wheel assembly, and a front roller assembly. The rear weight-bearing wheels, the center weight-bearing wheels, and the forward weight-bearing wheels are fixed to the frame at a height effective to cause the main weight-bearing surface to always have a “V”-shaped lower surface when viewed from the side. The center weight-bearing wheels, the forward weight-bearing wheels, and the front rollers are fixed to the frame at a height effective to cause that portion of each track drive always to have a “V”-shaped lower surface when viewed from the side. At least one powered drive wheel is provided, and at least one of the rollers is a tensioning roller.

摘要： Robotic systems include a frame or body with two or more wheels rotatably mounted on the frame or body and a motor for independently driving each wheel. A system controller generates a signal for actuating each motor based on information provided by one or more sensors in communication with the system controller for generating feedback signals for providing reactive actuation of the motors for generating one or more functions selected from the group consisting of forward motion, backward motion, hopping, climbing, and balancing. A power source is included for providing power to operate the drive motors, system controller and the one or more sensors.

摘要： An endless track is for use with a mobile robot and includes a belt, a plurality of chamfered cleats, a plurality of holes and a dual v-guide. The belt has an inner surface and an outer surface. The plurality of chamfered cleats, each have a contact surface. The chamfered cleats are attached to the outer surface defining an attachment area, and the contact surface is shaped such that when the track is laid on a flat solid surface, each chamfered cleat contacts the flat solid surface with less area than the attachment area. The plurality of holes in the belt are disposed between the chamfered cleats and are shaped to allow teeth of a drive sprocket pulley to pass through and to engage the belt for transmitting force from the sprocket pulley to the belt. The dual v-guide includes two elongate, parallel protrusions which are spaced laterally from each other and are attached to the inner surface.

摘要： Methods and systems for determining a status of a component of a device are provided. An example method includes triggering an action of a component of a device, and responsively receiving information associated with the action of the component from a sensor. The method further includes a computing system having a processor and a memory comparing the information with calibration data and determining a status of the component based on the comparison. In some examples, the calibration data may include information derived from data received from a pool of one or more devices utilizing same or similar components as the component. The determined status may include information associated with a performance of the component with respect to performances of same or similar components of the pool of devices. In one example, the device may self-calibrate the component based on the status.
