## Potential Design One

Taking inspiration from [ECO-worthy linear actuator controller](https://www.amazon.com/dp/B00JYAIS9W/ref=cm_sw_r_cp_apa_fabc_PGWD9GZZN7953B59Y202?_encoding=UTF8&psc=1)

This design does not have a rotational mechanism, but two linear actuators and three hinges. The hinges permit it to tilt in different directions, simulating a rotation.

Pros:

- Linear actuators can resist change in motion i.e. when you power them to a certain position, they will stay there and not consume extra power.
- Linear actuators are somewhat cheap
- All materials for this design can be bought locally, like Lowe's
- Existing template for this design exists. Maximum load with their actuator and trigonometry is 330 lbs, which is more than enough to carry five solar panels.

Cons:

- Linear actuators don't have encoders, so we would need to attach a position sensor or accelerometer to the motor.

Same linear actuators can be found on Banggood [Linear actuators](https://usa.banggood.com/1500N-12V-4681012-inch-Linear-Actuator-Adjustable-Actuator-Tor-Opener-Linear-Actuator-Motor-p-1115476.html?cur_warehouse=CN&ID=566086&rmmds=search)
