Question

Currently attempting to get some code to compile using Lejos for the Lego NXT brick. The command I run is nxjc Nxt_code.java and I get a Cannot find symbol error. TachoPilot has been imported. Here is the output from the console:

`Nxt_code.java:14: cannot find symbol
symbol  : class TachoPilot
location: package lejos.robotics.navigation
import lejos.robotics.navigation.TachoPilot;
                            ^
Nxt_code.java:25: cannot find symbol
symbol  : class TachoPilot
location: class NXT.Nxt_code
private TachoPilot pilot;
        ^

    TachoPilot pilot = new TachoPilot(WHEEL_DIAMETER, TRACK_WIDTH, Motor.B,

5 errors

Any suggestions on how to resolve this issue?

Answer 1

It’s not in 0.9b; not sure about 0.8.5, but it’s in 0.8.

I’ve seen a few impls, or copying it from 0.8 might work (with any tweaks necessary).
