HI, I am building a 360 Camera Robot using a wheelchair base and a Sabertooth Dual 2X32A Motor Driver. It drives and steers, variable speed, and is controlled by RC.
The GOAL- Place the Camera Robot at Point A and slowly drive it in and out and around people and objects on a musical stage to a Point B and make the drive path of the Camera Robot repeatable.
TRYING TO ACCOMPLISH- So if the Camera Robot is placed at Point A, I would like to hit a “RECORD” and begin the drive through (around props, people, etc. using my RC Transmitter) with some turns, maybe a stop or two, and then continue to end POINT B of its travel. Then Hit “STOP RECORD”. IF possible, hit a RESET TO A" and the Camera Robot would reverse and drive the exact same recorded path in reverse back to POINT A and then stop.
When ready to film, (Camera Robot would be back at beginning Point A) hit “DRIVE” and the Camera Robot would follow the exact path, same speed, with turns, and stops, until it reaches Point B.
I guess it would be akin to a motion control setup. Record time could be up to 5 minutes (if possible??)
Your input and suggestions are appreciated. Thank you.
Moving a mobile robot in a specific path could use the following:
Encoders: Encoders count the number of rotations of either the rear shaft of each of the drive motors (more counts per rotation of the wheel), or on the output shaft. These counts correspond to rotations of the wheel, which corresponds to the distance traveled by each wheel. robotshop.com/en/encoder-disks.html
Since you are indoors, GPS won’t be much of an option. There are indoor localization options as well:

You will need additional sensors in case objects have moved to obstruct the path of the robot.

A camera-based recognition system is really difficult to implement with so many variables.
A very simple (and much less expensive) setup would be if you could have the robot simply follow a line / path:

Hi Coleman,
THANK YOU for this information.
How thin can you go with a reflective line?
Also, is there any reflective tape that could be used?
The width of the tape depends on the sensors and their placement away from each other, as well as the distance from the surface to the sensor.
You need contrasting colors light solid black vs. solid white. Experiment a bit with tape.
I appreciate the information! Thanks
