The IR wireless connection served in many of our advanced projects. This just
gives you great possibilities with mobile robots.

Bluetooth is a very versatile RF-communication that could allow real flexible
networking for multi-agent applications. This would be a much faster
communication than slow IR.

Bluetooth would generate new projects with distributed sensors. I already have
some ideas... An I2C-bus would be helpful as well. If we have a look back to the
RCX, we must be amazed that a 32k device has been able to attract so many kids,
students and adults from 1997 to 2005, which is ENORMOUS time in computing.
During the same time I have changed my PC several times, upgraded most of my
programs... And still there are things to discover with the RCX. Because it was
an absolutely pioneer product. The new RCX must have comparable innovative power
than the old one.

| (...) Bluetooth has a maximum range of 30 feet. That's in optimum conditions. You might get down as low as 15 feet in real world applications. At 2GHz or so, it doesn't go through walls very well either. Bluetooth is DESIGNED to have short range - (...) (19 years ago, 1-Jun-05, to lugnet.robotics)
