A system for controlling a pitch of an endless track vehicle for driving the endless track vehicle in a given direction; monitoring a pitch angle of the endless track vehicle while moving along the given direction; and upon determining that the pitch angle is varying, controlling the driving of the endless track vehicle to control a rate of variation of the pitch angle of the endless track vehicle. The endless track vehicle may include a body defining a load bearing surface. Track(s) is rotatably mounted to the body to move the body. A motorization unit actuates the track(s). A drive system operates the motorization unit.

A robot includes a main body, a handlebar disposed on the main body and grippable by a user, a detection unit that detects a load applied to the handlebar, a moving device including a rotating body and moving the robot by controlling the rotation of the rotating body, and a switching unit that switches a support mode for supporting the user with walking. The support mode includes a first mode in which the robot autonomously moves to guide the user who is walking and a second mode in which the robot moves in accordance with a first load detected by the detection unit. When the robot moves in the first mode, the switching unit switches the support mode from the first mode to the second mode on the basis of the second load detected by the detection unit.

A shock damper is disposed between a vehicle body side and a wheel side. A suspension control device calculates a damping force of the shock damper on the basis of vehicle height information and controls the damping force. A steering system includes an electric motor and a steering control device that controls the electric motor, and assists steering effort of the driver through the electric motor. The suspension control device calculates the vibration generated in a steering on the basis of a detected value of a vehicle height sensor and creates a signal for generating steering torque that reduces the generated vibration. The suspension control device outputs the created signal to the steering control device. Steering torque for cancelling steering vibration is accordingly outputted from the electric motor of the steering system.

An amusement park attraction system including a ride vehicle comprising an input device, and a control system configured to determine a parameter value associated with a force imparted on the input device. The parameter value includes a value of the force imparted on the input device, a value of a deformation caused by the force imparted on the input device, or both. The control system is also configured to control movement of the ride vehicle of the amusement park attraction system based on the parameter value.

The present disclosure provides a stair climbing gait planning method and an apparatus and a robot using the same. The method includes: obtaining first visual measurement data through a visual sensor of the robot; converting the first visual measurement data to second visual measurement data; and performing a staged gait planning on a process of the robot to climb the staircase based on the second visual measurement data. Through the method, the visual measurement data is used as a reference to perform the staged gait planning on the process of the robot to climb the staircase, which greatly improves the adaptability of the robot in the complex scene of stair climbing.

A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.

A method for negotiating stairs includes receiving image data about a robot maneuvering in an environment with stairs. Here, the robot includes two or more legs. Prior to the robot traversing the stairs, for each stair, the method further includes determining a corresponding step region based on the received image data. The step region identifies a safe placement area on a corresponding stair for a distal end of a corresponding swing leg of the robot. Also prior to the robot traversing the stairs, the method includes shifting a weight distribution of the robot towards a front portion of the robot. When the robot traverses the stairs, the method further includes, for each stair, moving the distal end of the corresponding swing leg of the robot to a target step location where the target step location is within the corresponding step region of the stair.

A computer-implemented gait planning method includes: determining a pitch angle between a foot of the robot and a support surface where the robot stands; determining a support point on a sole of the foot according to the pitch angle; calculating an ankle-foot position vector according to the support point, wherein the ankle-foot position vector is a position vector from an ankle of the robot to a support point on a sole of the foot; calculating a magnitude of change of an ankle position according to the pitch angle and the ankle-foot position vector; and obtaining a compensated ankle position by compensating the ankle position according to the magnitude of change of the ankle position.

Disclosed is a mobile object including a body part, a drive part coupled to one side of the body part and including one or more wheels, and an accommodation part coupled to the other side of the body part and having an internal space capable of accommodating an article, in which the drive part is coupled to a lower region of the body part, and the body part is rotatably coupled to the drive part, and in which the accommodation part is coupled to an upper region of the body part, and the accommodation part rotatably coupled to the body part.
