A mobile character control system includes a platform, a character assembly, a control system, and a transportation assembly. The platform is configured to support an operator. The character assembly is engaged with the platform and includes actuatable features configured to simulate movement of a creature. The control system is configured to control activation of the actuatable features of the character assembly in response to signals received from control features controlled by the operator. The transportation assembly is configured to direct movement of the platform and to support the character assembly.

A control system for a surgical robot is provided. The control system includes a first embedded computer and a second embedded computer configured to receive status information from the first embedded computer. The status information includes a status of zero-return for a surgical tool driving module or an imaging tool driving module. The control system also includes a host computer configured to receive the status information from the second embedded computer. The surgical tool driving module or the imaging tool driving module includes a controller, a motor connected with a first coupling and configured to drive the surgical tool or an imaging tool, and a zero point switch configured to detect whether the first coupling is at a zero position. The controller is configured to transmit the status of zero-return to the first embedded computer based on whether the first coupling is at the zero position.

In a robotic surgical system, a controller is configured or programmed to change at least one of a level of an operation start assisting force, a level of an in-operation assisting force, or a level of a braking force based on a level change operation of an operator received by a level change receiver.

A method for engaging and disengaging a surgical instrument of a surgical robotic system including receiving a sequence of user inputs from one or more user interface devices of the surgical robotic system; determining, by one or more processors communicatively coupled to the user interface devices and the surgical instrument, whether the sequence of user inputs indicates an intentional engagement or disengagement of a teleoperation mode in which the surgical instrument is controlled by user inputs received from the user interface devices; in response to determining of engagement, transition the surgical robotic system into the teleoperation mode; and in response to determining of disengagement, transition the surgical robotic system out of the teleoperation mode such that the user interface devices are prevented from controlling the surgical instrument.
