5 Bruce的Appinventor教程

 

 Lesson 8: Using Vuforia to find targets, part of a series on using FTC App Inventor to create programs for the FTC Autonomous Period. 

In this lesson I cover configuring FTC App Inventor to use Vuforia including loading image files that allow an Autonomous OpMode to automatically recognize which of four Velocity Vortex target images the Robot Controller phone is viewing.

Note: FTC App Inventor versions 2.3 and 2.4 in effect in November 2016 have a bug that that doesn't clear old image files when an op mode is initialized causing an accumulation of trackables, keeping the op mode from working if it is initialized more than once. The robot controller application should be reloaded before each use to avoid the effect of this bug. I will post an update here when this bug has been corrected.
