There is only one legal starting square. I don’t understand this question…
If the students touch the robot, it must be returned to the starting square. Then, they can aim/position it however they want in that square, and run any program.
1, when the robot start in the programming match ,can student tuch the robot again ? (select program or tuch the bumper)
The student can touch the robot while it is anywhere on the field, but once touched it must be returned to the ONLY starting position and any balls that the robot was carrying when touched or grabed will be removed from game.
2,when the robot all back to the start field and stop ,can student change the robot’s direction during the match? (like vex)
Consider grabbing the robot and placing it back on the starting tile, may be faster than waiting for robot to come back.
3,when the robot stop at the one start field , can the student take the robot to another start field (same side) and start the robot again?
Student can take the robot back to the start field, but there is only one starting tile.
