1. A hand-holdable controller comprising:

  • a rotatable knob;

    at least one motor that is operable to apply torque to the rotatable knob;

    one or more touch sensors comprising at least one touch sensor arranged on a curved surface of the rotatable knob;

    a control system configured to;

    receive operating mode data indicating an operating mode for the rotatable knob;

    operate the at least one motor to apply torque to the rotatable knob in accordance with the operating mode data;

    receive touch data generated by the one or more touch sensors;

    based on a comparison of the touch data to predetermined grip data that specifies parameters for detection of a plurality of grips on the rotatable knob, detect when each of the plurality of grips occurs on the rotatable knob, wherein the plurality of grips comprises at least a first and second grip;

    detect a first rotation of the rotatable knob; and

    when the first rotation is detected in association with detection of the first grip, generate first command data for a robotic device; and

    when the first rotation is detected in association with detection of the second grip, generate second command data for the robotic device, wherein the second command data is different from the first command data.
