Very Fast VEX PID Line Following Robot

VEX line following robot as published in ROBOT magazine Sept/Oc 2009. Very fast -- compare with other video showing classical "zigzag" algorithm. About two feet per second. Uses a PID control algorithm and line following sensor from Pololu.

Written in ROBOTC. Speed limited by latency in the VEX motors.

Complete source code available in the sample programs shipped with ROBOTC (version 1.58 an above). See www.robotc.net. for download.

The stearing is very undstable see how it breaks at every corner if you adjust the stearing better it would go faster trough the turns.

This is really mechanical limitations in the VEX system. The motors do not respond as fast as some other systems do speed changes from software. Otherwise steering would be "smoother".

[dickswan1]

Yes. The VEX is mechanically challenged. Look at my other video of a slow "standard" VEX line follower.

fast..??

[nooblog]

Nice... but there is no tutorial on how to build a PID line follower for vex ... sad... i need it for my project

[mahchymk93]

Not that fast, my proportional controlled LFR is faster.

[orion1077]

if you're using PID, play around with the differential gain a little, it might help

[insopor1upiita]

it is not very fast

[TheXdmgx7]

lack of sensors is the main problem

it's not fast at all

[kepler5885]

Not fast.

How many Line Sensors did you use?

[karandex]

how can u get the code i am useing arduino?

[chamidilk]

fast

n PID

r u kidding
