TLA: Motion Test Video
This video shows a test of the truck and pan motions moving my K10D and Sigma 17-70. In this video, both are running at their maximum speeds (approximately 3.7 in/min for truck and 1 deg/sec for pan) and the video is running at twice normal speed.
There are still some problems to be worked out, especially with the cart and the software (it’s amazing the sorts of bugs that pop up only after motors have been attached!) – but I’m pleased with the progress thus far. However, I am a little concerned about the rough nature of the pan movement. Only being able to move 1 degree as a minimum movement will probably result in rough movements in the video. If it becomes problematic, I’ll have to replace the servo with a stepper motor. And, you know how these things go – if I have to use a stepper motor, I’ll likely have to add another arduino for motor control, or a break0out controller for the stepper, as I have no pins free on the arduino.
