Wild Rover

by Thomas Bonatti, Jared Hoffman, Ted Holmes, and Whirligig231

You are the operator of a deep space rover on a scientific mission.
Your job is to collect research samples by sending your rover commands to move it around the planet. 
Commands have a verb that affects a system, 

                                       entered as: 
                                                        "<verb> <system>" 
                                       such as: 
                                                        "more throttle" 

Commands:
"more" - Increases the use of a system;
"less" - Decreases the use of a system;
"stop" - Turns a system off (ie. "stop throttle");

Systems:
"throttle" - Move the rover forward or backward; 
    throttle can be set to 0, 1, 2, 3, or R (reverse);
"right" - Makes the rover start turning right;
"left" - Makes the rover start turning left; 
"more left" is equivalent to "less right";
"drill" - Starts drilling for rock samples;
    temporarily pauses movement while active;

WARNING: the further your rover is from the planet's radio control tower, the weaker your control signal gets and the greater the chance of a command getting corrupted. 
Corrupted commands can cause unintended behavior in the rover. 
A blue arrow points back to the control tower so you can always find your way back.

Your objective will be indicated with a green arrow. 
Activate the rover's drill while inside the objective circle to complete the objective. 

Collect as many rock samples as you can without running out of time!
