How to calibrate analog signal with velocity command?
Hi there,
Right now I'm trying to make an autonomous wheelchair. I am using an Arduino to write analog signals to two non-inverting op amps, which are connected to the X (controls forward and backward) and Y (controls rotation) pins of the wheelchair joystick control. All these op amps do is amplify the analog signal and output a voltage between 4 and 6 volts. I also have two encoders connected to the Arduino that will provide me with odometry information.
What is the best way for me to calibrate the magnitude and duration of analog signal required to obtain a particular velocity on my wheelchair? Are there any good ROS tools that I can use?
So far I have looked into rqt_plot and dynamic_reconfigure. I was wondering if there were any better options out there?
