Launch VEXcode VR now

Use [Drive for], [Turn for], [Spin for] blocks, and the Topline Tracker to drive the Hero Bot to the pile of three Discs highlighted in green, intake the 3 Discs, and score them in the blue Low Goal. 

  • Select the VRC Virtual Skills - Spin Up Playground.
  • Drive the Hero Bot to the pile of three Discs highlighted in green.
  • Code the Hero Bot to spin the intake motor group to intake the Discs, wait until the Topline Tracker detects the third Disc, and stop spinning the intake motor group.
  • Drive the Hero Bot to the blue Low Goal. 
  • Set the desired intake motor velocity and spin the intake motor group to score the Discs.

Helpful Hints

  • The Line Tracker sensor can detect the position of Discs within the intake and determine how many Discs are currently being held in the intake. 

  • Use the Reporter blocks from the Sensing category to get reflectivity values in % from the Line Tracker Sensor.

    VEXcode Reflectivity of block that reads 'BottomLineTracker reflectivity in %'.

    VEXcode Reflectivity of block that reads 'MiddleLineTracker reflectivity in %'.

    VEXcode Reflectivity of block that reads 'TopLineTracker reflectivity in %'.

    • Matching Python command:

      bottom_line_tracker.reflectivity(PERCENT)
middle_line_tracker.reflectivity(PERCENT)
top_line_tracker.reflectivity(PERCENT)
