2013-08-18 21:47:09 -0500 asked a question The face recognition package not have package.xml file


I got face recognition tutorial on ros wiki page:

and the SVN link for the face recognition package:

I tried to build the workspace using catkin_make command on groovy. But it not building the face recognition package. I had noticed that the package.xml file not exist in the face recognition package.

Hi, Thank you for support. Actually I am new to ROS. As per your suggestions I had tried to learn tf: . But i am not getting the logic/flow of using topic to accept velocity. Could you please suggest some links to study about: 1. Sending velocity to topic to control motor. 2. Using a package to control my robot. Thank you.

2013-07-30 18:59:17 -0500 asked a question How turtlesim can use for a real project


I am able to do following things:

  1. Able to run turtlesim node.
  2. Able to move turtle using keyboard.
  3. Able to move turtle in a specific path using terminal commands.

My doubt is how I can use turtlrsim or other packages in my real project?

I am going to make a basic robot with two motors and some sensors.

Could anyone tell me whether the the ROS software libs/packages are helpful in my robotic project? If yes how can i use it? Is there any useful links for this?

Can we use ROS for our own robot? ie, without buying the bases like PR2, Husky, TurtleBot, Kobuki etc. I can use a laptop inside my robot. I need to control the robot by a program installed in laptop. Whether i can use ROS in such a condition? Can i use ROS for controlling motors and various sensors in my robot?
