An omnidirectional treadmill environment simulator is disclosed. The omnidirectional treadmill environment simulator includes a circular simulator stage area, a plurality of transport mechanisms that maintain an object at or near the center of a circular simulator stage area and at least one processor. The processor is configured to collect position data of the object and process the position data to control the transport mechanisms. Also included is a receiver for receiving data from a remote location and a terrain analysis computer for processing the data received from the remote location. The terrain analysis computer collects the data received from the remote location to form an accurate simulation of an upcoming condition at the remote location. The omnidirectional treadmill environment simulator includes a transmitter for transmitting the position data to a remote location.

A service robot is provided to communicate with other devices of a service location, such as another robot. A first and second robot may be tasked with performing a customer service task requiring a physical interaction. The first robot may determine that the second robot lacks instructions to perform the customer service task. Upon making the determination, the first robot retrieves physical interaction instructions and causes the second robot to load and execute the physical interaction instructions. The second robot is then transformed, by the first robot, into a configured robot able to perform the customer service task.

A full-state control method for a master-slave robot system with flexible joints and time-varying delays is provided. In a teleoperation system formed by connecting a master robot and a slave robot through network, a proportional damping controller based on a position error and velocities, and a full-state feedback controller based on backstepping are designed for the master robot and the slave robot, respectively. High-dimension uniform accurate differentiators are designed to realize an exact difference to the virtual controllers. Delay-dependent stability criteria are established by constructing Lyapunov functions. Therefore, the criteria for selecting controller parameters are presented such that the global stability of the master-slave robot system with flexible joints and time-varying delays is realized. For the master-slave robot system with flexible joints, the global precise position tracking performance is realized by adopting a full-state feedback controller based on the backstepping method and the high-dimensional uniform accurate differentiators. Moreover, the global asymptotic convergence of the system is guaranteed and the robustness of the system is improved.

A medical manipulator system including: a medical manipulator having a joint; an operating section having an operating system; and a control unit controlling the medical manipulator according to an operation applied to the operating section. The operating section includes a switch enters or releases a command. The control unit determines whether a deviation between the joint and the operating system exceeds a threshold while the command is entered, carries out a first motion for moving the joint by a displacement corresponding to the displacement of the operating system if the deviation is equal to or smaller than the threshold, carries out a second motion for approaching the joint to the operating system angle if the deviation exceeds the threshold, and stops the motion for approaching the joint to the operating system angle when the command is released when the deviation exceeds the threshold.

Embodiments described herein relate to systems and methods for manipulating the position and/or orientation of an object while it is held in a robotic gripper. In one such embodiment, one or more physically possible and stable displacements for moving an object relative to a gripper using one or more frictional pushes may be determined and applied to the object to move the object from a first position and orientation to a second position and orientation while the object is held by the gripper. In certain embodiments, the physically possible and stable displacements may be determined using an appropriate motion cone approximation.
