Mobile self-leveling landing platform for small-scale UAVS
A mobile self-leveling landing platform vehicle is disclosed that includes a landing surface and one or more wheel assemblies. Each wheel assembly includes a wheel, a control arm coupled with the wheel and the body of the landing platform vehicle, and an actuator coupled with the control arm and the body of the platform vehicle. Methods for self-leveling the landing platform vehicle are also disclosed.
1. A method for leveling a mobile landing platform vehicle, the method comprising:
receiving inclinometer data from an inclinometer coupled with the mobile landing platform;
receiving actuator position data from at least one of a first linear actuator, a second linear actuator, a third linear actuator, and a fourth linear actuator;
determining an adjustment value for the first linear actuator based on the inclinometer data and the actuator position data; and
sending the adjustment value to the first linear actuator,
wherein the mobile landing platform includes:
a first actuating wheel assembly comprising the first linear actuator, a first wheel, and a first control arm coupled with the first linear actuator and the first wheel;
a third actuating wheel assembly comprising the third linear actuator, a third wheel, and a third control arm coupled with the third linear actuator and the third wheel; and
a fourth actuating wheel assembly comprising the fourth linear actuator, a fourth wheel, and a fourth control arm coupled with the fourth linear actuator and the fourth wheel.
2. The method according to claim 1 , wherein the adjustment value comprises a pulse width modulation signal.
3. The method according to claim 1 , wherein determining an adjustment value for the first linear actuator based on the inclinometer data and the actuator position data, further comprises determining the adjustment value for the first linear actuator based on the inclinometer data and the actuator position data of the first linear actuator and actuator position data of at least one of the second linear actuator, the third linear actuator, and the fourth linear actuator.
4. The method according to claim 1 , further comprising determining whether one or more of the first linear actuator, second linear actuator, third linear actuator, and fourth linear actuator is extended beyond a threshold value.
