Adding obstacle message

[farhanrahman]

I wanted to know if you could add a message that generated distance data to the haptic_interface (aka ANAS). I basically need that data to generate a force towards a particular direction. Just for everyone's information the formula that is going to be used to calculate the force is:

F = ((1/d1)^2 + (1/d2)^2))* ( exp (j ( 3pi/2 + (d1-d2) ) ) )

I hope it makes sense. We can talk about it tomorrow.

But ya I need someone to write a message in this repo that will contain distance data generated from both the sensors.

actually I might make that message in haptic_interface, then this node can use the message created there. We can always shift that message to this node later on...

its actually 3pi/2 - (d1-d2)....this is only specially for the case of two laser scanners pointing forwards as in our case...
