I need a sensor which send a pulse to the microcontroller when a object is very nearer to robot that is only at its front part of robot a arm like arrangement should GRAB it immediately , the gap should be around 8-10 cm, above which it should not sense it.

The object it needed to detect is a colored one, which type of Sensor i can use?

Sorry buddy, we are going to need more than two sentences to describe what you want. Try going into more detail. Maybe en entire paragraph or two would help. :stuck_out_tongue:

Thanks for your reply.

My project is as follows,

The sequence of operation of my robot is as follows,

  1. Spin around in the current position looking for a ball
  2. Approach the ball until sufficiently close and it will grab the ball.

I have designed my coding Using MATLAB until point 2, but inorder to grab it I dont want to use Image Processing commands using MATLAB i wanted to do entirely using sensors and micro controller. Could you let me know how I can implement ???

Also after Grabing the object,

  1. It search for object eg: a bin or a cone and it approaches closer to it and drops the ball near it and process 1 is started again , for this I am planning on Image Processing…

Kindly reply…

You can use IR or Sonar sensors to find your object. There is also a new “line” sensor that can be used with a tilt/pan of some sort to scan a view and detect the object’s edges. I bought one, but have yet to play with it.

Detect an object, change course to intercept object, when object is within range of you gripper (optical interruption switch on jaws?) grip object, lift object (or just push it), change course to new objective (goal), proceed to goal and deposit object! That should be simple! ;>)
