Thank You for your suggestion. I used follower plugin and robot starts moving when I put object in front of it. but robot does not start moving when launch my model using roslaunch. what changes i have to make to make robot move directly after starting the simulation.

Hi, I am doing swarm robots simulation on ros gazebo(ros indigo, Gazebo7, ubuntu 14.04). I want to use 802.11 wifi card in robot. is it available in gazebo or in ROS? I found WirelessTranmitter and WirelessReceiver files in bitbucket but I think it will not be useful. as every robot should transmit and receive signals.

Is there any other idea that i can make communnication between robots and get the RSSI(received signal strength indicator) value and calculate the distance between the robots and then i want to disperse the robots.

Thank you for your help. I want to make swarm robotics in gazebo. and i wanted wifi plugin but it is not available. I found transreceiver and transmitter files but has diff models. Is there 802.11 card available , so I can make robot sense the RSSI value and calculate the distance. after getting the distance robot should move away form each other. Can you tell me how should I start?

I am using ROS indigo and gazebo 7 and new to this area. I have gone through some tutorials from gazebosim website where I found diff_drive robot. It is for to move robot according to x y z values. I want to make that autonomous. Can you help me with that that how can I move robot some meters and then take right or left turn. I am using hokuyo laser model. I want to move robot left or right when the laser sense that the object is 1 meter away. I guess i need c file for this but i don't know where to find the file and how to use this c file.
