Why not using two stepper motors to move a camera on a 3D printer-made slider and pan it as it moves tracking an object? Actually, the control behind this robot is pretty simple… so lets create it!
First, a glance to its capabilities:
- Distance from the object to the rail
- Distance from the object to the camera when it started to move
With these two values, the Arduino will be capable of knowing the camera position according to the object to track just calculating the arc-tangent. Easy!The speed and start/stop “button” are controlled from your own smartphone. For this, the smartphone has to be connected to the robot´s WIFI network. More details below.
As the speed can be adjusted as desired (from the smartphone), you can move the “camera carriage” as slow as desired, making possible to create TIME LAPSE videos. Example of a 15 minutes video condensed into a 15 seconds video:We are still designing (finishing) the 3D parts and polishing the Arduino code but everything will be available soon. We will post details in the community in the next few days so you can create and play with the robot if you want
