(...) Well, actually, that code works fine (running MacNQC, a fairly recent version, with 2.0 firmware). One thing to check, code-wise, is to display SENSOR_1 on the LCD, and see what the numbers are (is it set to raw mode? Is the sensor bad (I've (...)

I did this in the past (since disassembled the bot) and found it to be quite reliable; except on slippery surfaces and carpet. :) The trick that I employed was to gear-up the rotation sensor. This causes the rotation sensor to detect even a slight (...) (20 years ago, 11-Jun-04, to lugnet.robotics.rcx.nqc)

Have you come across the adder/subtractor drive? Although it make the gear chain slightly more complex - it may mean you can leave out the sensor entirely. The drive has two inputs (A and B), and two outputs - one being A+B, and the other A-B. So if (...) (20 years ago, 10-Jun-04, to lugnet.robotics.rcx.nqc)
