摘要： A system, method, and computer program product for generating dynamically feasible whole-body motion of a humanoid robot while realizing specified upper-body task motion are described. A kinematically feasible upper-body motion is generated based on the specified upper-body motion. A series of zero-moment points (ZMP) are computed for the generated motion and used to determine whether such motion is dynamically feasible. If the motion is not dynamically feasible, then the torso acceleration is modified to make the motion dynamically feasible, and otherwise synchronized as needed. A series of modified ZMP is determined based on the modified torso acceleration and used to distribute the resultant net ground reaction force and moment to the two feet.

摘要： A driver assistance system is described that takes as input a number of different types of vehicle environment inputs to provide driver assistance to a driver. To provide the assistance, the driver assistance system synthesizes the inputs. For objects in the vehicle environment detected in the inputs, object risk values are determined by applying a set of rules to the objects. The object risk values are aggregated by quadrant to generate a set of quadrant risk values. A driver assistance system of the vehicle is controlled based on the quadrant risks.

摘要： A system, method, and computer program product for avoiding collision of a body segment with unconnected structures in an articulated system are described. A virtual surface is constructed surrounding an actual surface of the body segment. Distances between the body segment and unconnected structures are monitored. Responding to an unconnected structure penetrating the virtual surface, a redirected joint motion that prevents the unconnected structure from penetrating deeper into the virtual surface is determined. The body segment is redirected based on the redirected joint motion to avoid colliding with the unconnected structure.

摘要： A method for obtaining an assist torque to be applied to a human joint, in a human assist system for applying an assist torque to the human joint to reduce load of muscles, and the human assist system are provided. The method comprises the step of obtaining a moment due to gravity, acting on a joint of each human segment, based on equations of force and moment balance on each segment. The method further comprises the step of obtaining an assist torque to be applied to the joint to compensate for the moment due to gravity, acting on the joint. The human assist system comprises a motor for delivering an assist torque to a joint and a motor driver for driving control of the motor. The system further comprises a controller for determining a desired value of an assist torque, comprising a processor and a memory. The controller is configured to obtain a moment due to gravity, acting on a joint of each human segment, based on equations of force and moment balance on each segment and then to obtain an assist torque to be delivered to the joint to compensate for the moment due to gravitational acceleration at the joint.The method provides a natural subdivision between the voluntary actuators which are responsible for forward progression of motion and the assist actuators which are responsible for preserving static equilibrium. This subdivision may mitigate the interference between voluntary control and artificial control.

摘要： Systems and methods are presented that cancel the dynamics of a motor and a joint controller in the presence of communication time delays, measurement noise, and controller parameter uncertainties inherent in a robot system. A cancellation system includes feedback of the measured output Ê of a controller block C. A first summing node (Σ1) subtracts Ê from the desired voltage Ed to determine a voltage error, which is fed into a G(s) block. A second summing node (Σ2) adds the output of the G(s) block to the desired voltage Ed to generate the signal E, which is fed into a non-robust controller inversion block C−1. The block C−1 outputs a value μ, which is fed into the block C. The block C outputs the actual voltage E, which is input into a motor block M. Under perfect conditions, the voltage error is zero, in which case the input to block G(s) is zero.
