WRO 2020 Senior 53s Best Run

This robot WON the WRO 2020 Senior (check out the video in our channel).
Motor usage:
2 medium motor for movement
1 large motor to grab 2 concretes
1 large motor to lift 1 concrete, take sandbags & drop notices
Sensor usage:
2 color sensors for line following
1 color sensor in front to scan dikes & sandbags
1 color sensor in the back to scan concretes
(since the concretes & sandbags placement were fixed during the competition, we disabled the functions though. We only scan the dikes color)

OMG it so cool.
If the big block isn’t beside the robot.
How to pick up two block in the same time?

[@funroboid]

Thanks
If the first grab doesn't get 2 blocks (only one is beside the robot), we add movements: going back a little, spin, open the arms and then move toward the outside block and grab it.
