A new year, a new project!
We’re cooking up something new at Dexter’s labs: a wireless sensor. Working with some partners at Carnegie Mellon’s Robotics Academy and ROBOTC in development of hardware in support of CMU’s Fire Project, we’re developing a wireless sensor that will be able to reach up to 90 meters or 300 feet. The device uses XBee radios to communicate between NXT’s.
The possibilities are endless . . .
We should have this rolled out within a month or so. Check back for updates soon!
I’m interested in these sensors for inter robot comms. However what is the max throughput since you’re using the NXT i2c ports I presume?
TC,
This sensor actually uses Port 4 RS485 communications, so it’s much faster than I2C. We have run it up to a baud rate of 115200. That’s over 100 kbps.
The I2C port communicates at 9600 bits/second (9.6 kbps).
Hope that helps!
