The cage is held in place by a multi-axis gimbal system (thus the “GimBall” name), allowing the cage to rotate and roll indepedently of the propeller/camera rig at its core.
Surrounding the GimBall’s drone core is a spherical cage which serves three purposes: letting it roll along the wall or ceiling, keeping the device’s propellers away from your skin, and absorbing shock to keep the device in the air.
