Hello community! I have an alphabot2-Ar ( https://www.waveshare.com/wiki/AlphaB... ) and a wifi module ESP8266 to communicate with the PC. How can i send sensor information from the robot to the PC so that i can send the movement commands back to the arduino in the robot from my PC?

Thanks, but is it possible to, with only this components control the robot with ROS? Do i have to "Rosify" my robot to pass the \cmd_vel commands and so on?

You can either write a ROS wrapper around a client that deals with the data from the robot or you can try implementing ROS libraries in the Arduino itself: http://wiki.ros.org/rosserial_arduino

There is a nice sample for using ESP8266 and ros at github. It demonstrates the usage of the cheap ESP WiFi device.
