Abstract
A command interpreter is in communication with a wireless controller. The command interpreter is configured to identify a reference location of the wireless controller, identify a second location of the wireless controller, and determine, based on the reference location and the second location, a sequence of instrument commands configured to adjust positioning of the instrument device.
Claims20
A system configured to receive a user input and control an instrument based on the user input, the system comprising:
- a wireless controller for receiving a user input, the wireless controller comprising:
- a first body element including a first location measurement device, and
- a second body element including a second location measurement device, wherein the first body element is movable relative to the second body element in six degrees of freedom;
- and
- a command interpreter configured to:
- receive first location information from the first and second location measurement devices,
- identify a first location of the first body element relative to the second body element from the first location information,
- receive second location information from the first and second location measurement devices,
- identify a second location of the first body element relative to the second body element from the second location information,
- detect the user input based on the first location and the second location, the user input comprising motion of the first body element relative to the second body element, and
- determine a sequence of instrument commands for adjusting, in accordance with the user input, a position or orientation of an instrument coupled to an instrument driver.
A method of translating a user input into a command for a robotic instrument driver, the method comprising:
- receiving a user input at a wireless controller, the wireless controller comprising a first body element and a second body element, wherein the first body element is movable relative to the second body element in six degrees of freedom;
- identifying, by a command interpreter, a first location of the first body element relative to the second body element;
- identifying, by the command interpreter, a second location of the first body element relative to the second body element,
- detecting the user input based on the first location and the second location, the user input comprising motion of the first body element relative to the second body element, and
- determining a sequence of instrument commands for adjusting, in accordance with the user input, a position or orientation of an instrument coupled to an instrument driver.
