Nobody who can help us out on this one?? I'm looking for the NQC comando's that
can control (readout) the sensor on the rear of the spybot.. This can be used as
told above to determen if the beacon is in front of the spybot.. Or behind the
spybot.. That all to give the spybot a better left right sense..
The sensor that is in the back is SENSOR_2 And can be used for IR comunication
trough air.. But i'm not pretty sure how to put things together..

| Hi Daniel, I can't really help you all that much, but some thoughts on my own experiments regarding the use of direction/range with the Spybot. I have found the direction readings to be very poor when the object is in zones there or anywhere. Once (...) (19 years ago, 4-Oct-05, to lugnet.robotics.spybotics)

| (...) There was a bug in the code generated by NQC for the find opcode prior to version 3.1r2. If you are using a version of NQC older than 3.1r2 then that *might* explain why Brian's beacon.nqc program fails to work sometimes. I will try to find a (...)
