Advice on Servo Pan and til kit to airborn drone

Community General Discussions

My friend and I are building a drone project.
For this project we need to mount a HD video camera in the bottom of the drone.

Maneuvering specs:
The camera needs to rotate 360 degrees around its own axe and enable tilting downwards / upwards.

Weight specs:
Because of the drone are airborn we need to go as light as we can regards to the tilt kit.
at the same time we need to be able to tilt / move a cam that weighs 220g.

We are new to robotics and need some advice on what Servo Pan Tilt kit we should buy.
All advice and considerations is appreciated.
Are there issues or considerations that we need to have, then please share your knowledge 

If you need more information just replay and I will provide :slight_smile:
looking forward to hear from you

Hi MIP_DRONE,

Welcome to the RobotShop Forum. In order to determine which pan/tilt system will work, you need to determine the torque which will act on the tilt servo. If we assume the center of mass of the camera is about 5cm away from the pivot, and a worst case scenaro being the camera needs to point upwards (or directly downwards), then the torque required by the servo would be 5cm x 0.22Kg = 1.1 Kg-cm. If you are considering the Lynxmotion mini pan/tilt system, the Hitec 85BB servo can provide up to 3.5Kg-cm, which is more than enough.

Hope this helps,
