SRI Demonstrates Robot to Robot E-mail

It is quite possible that this past Tuesday marked the first time in history that a robot has exchanged e-mail over the internet with another robot. In a demonstration of the SR4 Autonomous Mobile Robot manufactured by Smart Robots, Inc., a software engineer at the firm, Dennis Koch, while sitting with a wireless laptop in a restaurant in another part of building, sent an e-mail off to Smart4, the first of two wireless robots in the test, to ask for the temperature both at the office and at the home of the CEO of the firm, Joe Bosworth, who lives about a mile away.

SRI Demonstrates Robot to Robot E-mail

Dalton, Massachusetts    June 12, 2003

It is quite possible that this past Tuesday marked the first time in history that a robot has exchanged e-mail over the internet with another robot.

In a demonstration of the SR4 Autonomous Mobile Robot manufactured by Smart Robots, Inc., a software engineer at the firm, Dennis Koch, while sitting with a wireless laptop in a restaurant in another part of building, sent an e-mail off to Smart4, the first of two wireless robots in the test, to ask for the temperature both at the office and at the home of the CEO of the firm, Joe Bosworth, who lives about a mile away. In moments, Smart4, the robot in the office, received the message, shot back a reply to Koch, with five rapid-fire readings of the robots temperature sensor, then sent a similar message to the second robot, named Watson for this event, after Thomas A. Watson, the assistant to Alexander Graham Bell who received Bells first successful experimental phone message in 1876. Watson, the second robot in this test and located at Bosworths home, received the message from Smart4, and responded by also sending a set of five consecutive temperature readings to Koch, still at the restaurant just a few moments more after having sent the initial message to Smart4.

People e-mailing robots. Robots e-mailing robots. Robots e-mailing people. Little may surprise us about what is possible over the Internet or the World Wide Web as it is otherwise known. The robots in this case (models SR4-P and above) come standard with the ability to wirelessly hook into the Internet via standard wireless computer networks (WiFi) found in many homes and offices these days.

But are the parties in this test really talking to one another and understanding one another? Well, the answer is a qualified yes. Through the use of XML, or eXtensible Markup Language, people can speak to machines (robots in this case) by sending messages with code tags around the meaningful parts of the message --- for example being a possible tag signifying that the following text is an action request of the recipient by the sender. In this case, the full line of text might be temperature, with a tag at both ends indicating the beginning and the end of the action request, and the action request text itself being the word temperature".

The robot at the receiving end of this message has the ability to recognize code words (tags) and isolate the meat of the message, in this case, the text between the tags --- temperature". The robots programming enables it to interpret this message (or other similar messages) into an appropriate action associated in the robots memory with that message. The robot acquires the temperature readings from its on-board temperature sensor, and quickly sends the temperature readings to an e-mail address received in the initial message, bracketed by e-mail address tags. [Note: The actual XML code used in Tuesdays demonstration is somewhat different than this, but works in quite the same way.]

The first robot in this example, also then shoots off a message requesting the temperature from the second robot, which happens to be sitting a mile away from the office in this case, but, in fact, could be half-way around the world. The second robot receives and interprets the message and then takes and returns its own temperature readings to Dennis Koch.

According to Joe Bosworth, the matter of the 'qualified yes in an earlier response to the question of the robots understanding, is merely to underscore that it will be quite a while, if it is to happen at all, before a machine can be said to 'understand in a conscious sense what is going on around it. But smarter and smarter machines should eventually be able to respond to many events and circumstances with appropriate responses that make them seem intelligent, if not understanding as well."

Today, the SR4 robot that Smart Robots, Inc. introduced earlier this spring, is targeted for students, engineers, hobbyists and educators, to provide an educational and experimental platform for learning and applying Linux, Java, XML, Web Services, Wireless Ethernet Networking and other information technology skills that are in demand in the computer field today. Younger students in elementary grades can practice their language and math skills by teaching" the robot these same skills. Others will find the robot useful in learning about electronics, robotics and sensor technology.

And all of this while having some fun with a new technology", says Bosworth.
