Good day to all.
First of all, I'd like to clarify that the intention of this question is not to solve the localization problem that is so popular in robotics. However, the purpose is to gather feedbacks on how we can actually measure the speed of the robot with external setup. The purpose is to be able to compare the speed of the robot detected by the encoder and the actual speed, detected by the external setup.
I am trying to measure the distance traveled and the speed of the robot, but the problem is it occasionally experiences slippage. Therefore encoder is not accurate for this kind of application.
I could mark the distance and measure the time for the robot to reach the specified point, but then I would have to work with a stopwatch and then transfer all these data to Excel to be analyzed.
Are there other ways to do it? It would be great if the external setup will allow data to be automatically sent directly to a software like Matlab. My concern is more on the hardware side. Any external setup or sensors or devices that can help to achieve this?
