The challenge I faced was that, when using a stationary camera for streaming conferences or events, we had to readjust the camera position every time the panel discussion changed. This led me to explore the possibility of remotely controlling the camera position.
Following my research, I identified potential solutions. However, I aim to simplify and reduce the cost of implementing these solutions.
The endeavor involves creating a compact motorized head designed for effortless installation on a camera tripod. It can be conveniently controlled through Bluetooth using a mobile device, allowing for precise orientation adjustments in both horizontal (left or right) and vertical (up and down) directions.
Here are some initial sketches showing the concept of the device
small base contains the brain and the BT module connected with two motors
the base motor can be connected directly to the base
the other motor will be on the axis to move up and down
Construction Parts
Laser-cut plywood and some gears and brackets printed with the 3D printer
Input
(Sensing, Tactile Input, and/or Graphical Input)
The main input is the Bluetooth module using mobile, and I'll use it as an input sensor
Action
(Physical and/or Graphic)
The actions will be physical " turning around the axis for 180 degrees, and turning forward and backward for 45 degree
Brain
Arduino Uno, or Nano
Power Management
the power source will be external power, 9v adaptor
The base part contains power on and off, power in, power red led, Bluetooth blue led, and the brain
The top part contains the moving axis for the front and back and the camera mount
The moving part can be installed on the base
