Help needed in obstacle avoidance robot

[muza1988]

Hi,

I am working on a project where I am supposed to make a robot that will avoid obstacle e.g a wall in front of it using ultrasonic sensors. I don't have schematics for that. I need the schematics for this kind of robot. Can anyone help me regarding this?

Thanks

Another link that explains some basic but useful sensors and how they can be used for robotic obstacle avoidance: **broken link removed**. This **broken link removed** might also be helpful, it explains a very basic robotic task using, tracking the light, using 2 light sensors.
