Abstract: A trajectory planning method, a computer-readable storage medium, and a robot are provided. The method includes: constructing a phase variable of a trajectory planning of a robot, where the phase variable is a function of two position components of a torso of the robot on a horizontal plane; and performing, using the phase variable replacing a time variable, the trajectory planning on a swinging leg of the robot in each preset coordinate axis direction. In this manner, the robot can no longer continue to follow the established trajectory after being disturbed by the environment, but make state adjustments according to the disturbance received to offset the impact of the disturbance, thereby maintaining walking stability and avoiding the problem of early or late landing of the swinging leg.

Abstract: Systems, methods, and non-transitory computer-readable media for a remote vehicle immobilizer. A network gateway device receives a command from a remote computing device to modify a configuration of an electronic switch from a first configuration to a second configuration. The electronic switch is positioned in a conducting path between a starter motor of the vehicle and a battery of the vehicle. In response to receiving the command, the network gateway device transmits a signal to the electronic switch via a two-way communication channel connecting the network gateway device to the electronic switch. The signal causes the electronic switch to modify the configuration of the electronic switch from the first configuration to the second configuration.

An input related to a surgical operation includes a three-dimensional (3D) model for an organ with cut points on the organ forming a surgical trajectory. A surgical instrument is controlled by a robot to reach the cut points to carry out the operation. An insertion location for inserting the surgical instrument is identified. Based on the identified insertion location, a robot base location is determined with respect to the identified insertion location to deploy the robot for controlling the surgical instrument to reach the cut points. Signals for configuring the surgical setting are then generated based on the insertion location for the surgical instrument and the base location for the robot.

Abstract: A method of optimizing a suspension system to avoid pitch resonance may include determining pitch characteristics of a vehicle for a terrain profile and speed range via a model associated with the vehicle, decoupling front and rear axles by removing pitch inertia from the model, and determining optimized damping for a main damper of a position sensitive damper over a linear range of wheel travel in a bounce control zone based on the pitch characteristics. The method may further include recoupling the front and rear axles by adding the pitch inertia back into the model, and selecting a secondary damper associated with a compression zone or a secondary damper associated with a rebound zone as a selected damper for adjustment based on which of the front and rear axles is limiting. The method may also include performing a damping adjustment to the selected damper and cyclically repeating selecting the secondary damper and performing the damping adjustment until pitch resonance is suppressed.
