A concept camera gimbal.
I created this project to learn about different control system algorithms, mainly the PID (Proportional Integral Derivative) Algorithm. This camera gimbal detects its orientation through the use of a 9-axis accelerometer and shifts its position via 3 geared DC motors.
I built two prototypes of this device. Rev 1 (left) only had 2-axis control and used a simpler accelerometer. Rev 2 (right) had 3-axis control and utilized a more advanced sensor and motor controller.
