Dear Sirs,
I just found about your new robot MRP-1 project on YouTube and very interested about it.
I am looking to find a way to make a robot to follow his owner just like MRP-1 , I have already came up with the idea of using a pair IR Beacon sensors but it's not a good way since user should always point it to the device, When I saw your MRP-1 project on YouTube I thought that you used a better way than IR Beacons but didn't get it, you said that you used Hokuyo Laser Range Finder sensor on you robot but I don't know how dose it follow the person and how dose it recognize that person from others? would you please tell me about your solution for this problem? what kind of sensor did you used it on MRP-1 to follow that person?
I'm willing to buy the sensor if you sell it.
any advice is much appreciated,
