LIDAR sensor attached to an actuator
View Patent ↗An apparatus and a method for steering a chip scale LIDAR. A light detection and ranging apparatus includes an actuator with at least one pocket and at least one channel connected to the at least one pocket formed inside a material below a top surface of the actuator, a chip scale LIDAR attached on the top surface of the soft actuator, at least one pump connected to the at least one channel, and an actuation controller configured to control the at least one pump and to activate at least one mode of the actuator.
1. A light detection and ranging apparatus, comprising:
an actuator including at least one pocket and at least one channel connected to the at least one pocket formed inside a soft material below a top surface of the actuator;
a chip scale lidar attached on the top surface of the actuator;
at least one pump connected to the at least one channel of the actuator; and
an actuation controller configured to control the at least one pump and to activate or deactivate at least one mode of the actuator.
2. The apparatus according to claim 1 , wherein a first pocket of the at least one pocket is separate and independent from a second pocket of the at least one pocket.
3. The apparatus according to claim 1 , wherein the at least one channel receives input from only one pump of the at least one pump.
4. The apparatus according to claim 3 , wherein the at least one pump is a pneumatic pump that discharges air to the at least one channel connected to the at least one pump.
5. The apparatus according to claim 4 , wherein the air discharged from the at least one pump is directed by the at least one channel to the at least one pocket causing a bump to be formed on the top surface of the actuator.
6. The apparatus according to claim 1 , wherein the actuation controller is configured to simultaneously activate or deactivate one or more pumps of the at least one pump.
7. The apparatus according to claim 6 , wherein the actuation controller is configured to activate one or more pumps of the at least one pump to activate a first mode of the at least one mode of the actuator.
8. The apparatus according to claim 7 , wherein the first mode of the at least one mode of the actuator steers the chip scale lidar into a first position.
9. The apparatus according to claim 8 , wherein the first position of the chip scale lidar corresponds to a first angle with respect to the top surface of the actuator, a first scanning direction, and a first scanning range of the chip scale lidar.
10. The apparatus according to claim 1 , wherein the chip scale lidar is attached to the top surface of the actuator with a corner of the chip scale lidar attached directly above the at least one pocket.
11. A method for steering a chip scale lidar attached to an actuator, the method comprising:
activating, using processing circuitry, a first mode of the actuator to steer the chip scale lidar to a first position;
activating, using the processing circuitry, one or more pumps corresponding to the first mode of the actuator;
activating, using the processing circuitry, a next mode of the actuator to steer the chip scale lidar to a next position;
activating, using the processing circuitry, one or more pumps corresponding to the next mode of the actuator; and
determining, using the processing circuitry, whether steering of the chip scale lidar can be stopped.
12. The method according claim 11 , wherein activating the first mode of the actuator creates a first set of bumps on the top surface of the actuator.
13. The method according claim 11 , wherein activating the next mode of the actuator deactivates a previously active mode of the actuator.
