ROBOT SYSTEM AND METHOD FOR PREDICTING LIFE OF REGENERATIVE RESISTOR
A robot system includes a motor provided at a joint, a regenerative resistor that consumes a back electromotive force generated by rotation of the motor as heat, and a controller configured or programmed to predict a life of the regenerative resistor based on a period of time during which the regenerative resistor is consuming heat.
Composite motion robot based on springtail movement mechanism
The invention relates to a composite motion robot based on springtail movement mechanism, which includes a body, a jumping mechanism, a balance wheel and a control module. The body includes a right pallet, a U-shaped frame, a curved slide, a casing, a fixing plate, a left pallet and a pin block; the control module is installed on the body. Based on springtail jumping motion mechanism and by setting the jumping mechanism and the balance wheel, the invention enables the robot to have capability of movement, such as jumping over obstacles, balance wheeled translation, flipping posture reset, and self-balance resetting which is otherwise difficult to be achieved by traditional balancing carts, etc.
Humanoid robot and its balance control method and computer readable storage medium
A humanoid robot and its balance control method and computer readable storage medium are provided. Expected accelerations of each of a sole and centroid of a humanoid robot corresponding to a current expected balance trajectory and an expected angular acceleration of the waist corresponding to the current expected balance trajectory are obtained based on current motion data of the sole, the centroid, and the waist, respectively first, then an expected angular acceleration of each joint meeting control requirements of the sole, the centroid, and the waist while the robot corresponds to the current expected balance trajectory is calculated based on an angular velocity of the joint, the expected accelerations of the waist, the sole, and the centroid, respectively, and then each joint of the robot is controlled to move at the obtained expected angular acceleration of the joint based on the angular displacement of the joint.

The method includes a step for locating the coupler of the suspender at a given first position, a step for locating the object at a given second position, a step for causing the robot to hold the coupler located at the first position and coupling the held coupler to the object located at the second position, and a step for causing the suspending moving device to move, by the moving mechanism, the object coupled to the coupler together with the suspender.
MOTION STATE CONTROL METHOD AND APPARATUS, DEVICE, AND READABLE STORAGE MEDIUM
This application relates to the field of robot control, and provides a motion state control method and apparatus, a device, and a readable storage medium. The method includes the following steps: Step 301: Acquire basic data and motion state data, the basic data being used for representing a structural feature of a wheeled robot, and the motion state data being used for representing a motion feature of the wheeled robot. Step 302: Determine a state matrix of the wheeled robot based on the basic data and the motion state data, the state matrix being related to an interference parameter of the wheeled robot, the interference parameter corresponding to a balance error of the wheeled robot. Step 303: Determine, based on the state matrix, a torque for controlling the wheeled robot. Step 304: Control, by using the torque, the wheeled robot to be in a standstill state.
Robots with dynamically controlled position of center of mass
Dynamic control of a center of mass position is based on replacement of discrete motion of macro body (counterweighing solid or counterbalancing mechanisms) for continuous molecular flow of counterweighing liquid. Redistributing liquid counterweight between chambers attached to independently moving parts of robot allows its motion to new stable position without disruption in static stability and dynamic balance. Various embodiments include bipods/humanoids, wheeled locomotion robots and hybrid wheeled/multi-pod bio-like robotic systems; some embodiments allow reversible mutual reconfiguration between various structural arrangements. In humanoid embodiments, method allows moving on uneven terrain or ascending staircases while maintaining static stability; method also decreases the probability of fall and secures self-rising if a fall occurred. In some embodiments liquid counterweight may be transferred upon high barriers exceeding the height of robot by a few folds, such as walls of the building or ledge or steep slope in mountains, thus providing robots with capability principally not available to prior art.
Robot control
Methods, apparatus, and computer readable media applicable to balancing robots. Some implementations are directed to maintaining a given end effector pose (relative to a world frame) of an end effector of a balancing robot when there is a disturbance to a balancing base of the balancing robot. Some implementations are additionally or alternatively directed to transitioning a balancing robot from a fallen configuration to a balanced configuration. Some implementations are additionally or alternatively directed to mitigating the risk that a balancing robot will fall when interacting with actuable environmental objects (e.g., doors) and/or to lessen the disturbance to a balancing base when interacting with actuable environmental objects.
