Abstract
Hand controls for an aircraft, including a single axis hand control which is configured to control movement of an aircraft along a vertical axis where the aircraft includes a plurality of rotors that are attached to the aircraft at a fixed position and the plurality of rotors rotate independently of one another. The hand controls further include a three axis hand control which is configured to control movement of the aircraft within a plane defined by a roll axis and a pitch axis, as well as about a yaw axis.
Claims18
A system, comprising:
- a single axis hand control which is configured to control movement of an aircraft along a vertical axis, wherein:
- the single axis hand control includes a thumbwheel which is attached to a left handgrip;
- the aircraft includes a plurality of rotors that are attached to the aircraft at a fixed position;
- and
- the plurality of rotors rotate independently of one another;
- and
- a three axis hand control which is configured to control movement of the aircraft within a plane defined by a roll axis and a pitch axis, as well as about a yaw axis, wherein the three axis hand control includes a fingertip joystick which is attached to a right armrest.
A method, comprising:
- receiving a forward velocity associated with an aircraft, wherein the aircraft includes a multicopter with a plurality of rotors which rotate in a substantially horizontal plane;
- determining a pitch offset based at least in part on the forward velocity, wherein the pitch offset changes monotonically with the forward velocity;
- determining a desired pitch based at least in part on the pitch offset and a pitch angle specified via a three-axis hand control, wherein:
- the three-axis hand control is configured to control movement of the aircraft within a plane defined by a roll axis and a pitch axis as well as about a yaw axis;
- the three-axis hand control includes a fingertip joystick which is attached to a right armrest;
- and
- determine a plurality of control signals for the plurality of rotors based at least in part on the desired pitch and desired movement along a vertical axis, wherein the movement along the vertical axis is indicated by input received from a single-axis hand control, the single-axis hand control including a thumbwheel which is attached to a left handgrip.
A method, comprising:
- receiving a forward velocity and a roll angle associated with an aircraft, wherein the aircraft includes a multicopter with a plurality of rotors which rotate in a substantially horizontal plane;
- determining a yaw rate offset based at least in part on the forward velocity and the roll angle, wherein the yaw rate offset increases over a first forward velocity range and decreases over a second forward velocity range and the yaw rate offset changes monotonically with the roll angle;
- determining a desired yaw rate based at least in part on the yaw rate offset and a yaw rate specified via a three-axis hand control, wherein:
- the three-axis hand control is configured to control movement of the aircraft within a plane defined by a roll axis and a pitch axis as well as about a yaw axis;
- the three-axis hand control includes a fingertip joystick which is attached to a right armrest;
- and
- determining a plurality of control signals for the plurality of rotors based at least in part on the desired yaw rate and desired movement along a vertical axis, wherein the movement along the vertical axis is indicated by input received from a single-axis hand control, the single-axis hand control including a thumbwheel which is attached to a left handgrip.
A method, comprising:
- receiving a forward velocity and a yaw rate associated with an aircraft, wherein the aircraft includes a multicopter with a plurality of rotors which rotate in a substantially horizontal plane;
- determining a roll angle offset based at least in part on the forward velocity and the yaw rate;
- determining a desired roll angle based at least in part on the roll angle offset and a roll angle specified via a three-axis hand control, wherein:
- the three-axis hand control is configured to control movement of the aircraft within a plane defined by a roll axis and a pitch axis as well as about a yaw axis;
- the three-axis hand control includes a fingertip joystick which is attached to a right armrest;
- and
- determining a plurality of control signals for the plurality of rotors based at least in part on the desired roll angle and desired movement along a vertical axis, wherein the movement along the vertical axis is indicated by input received from a single axis-hand control, the single-axis hand control including a thumbwheel which is attached to a left handgrip.
