Robot Arm C

Is there a penalty if you leave an end effector on the field?

no

I have a question about the scoring.

Lets say I got 5 pencils in the west egg carton, 5 lego blocks in the north egg carton, 5 ping pongs in the east egg carton (two of the ping pong balls were in the slots labeled "B" for the east goal), and all four dice were flipped to six and in the north zone. Also all the egg cartons are in the north zone. I calculated it to add up to 107 (103 being the max score) but my teammate says it is 92.

Just wondering who is right?

@windu34 how do you know?

Also, so we can use a computer to power the 5v rail on the arduino?

Max score is 110, check the rules clarification on sonic.org
I believe you would be correct, but I do not have the rules in front of me.

The rules do not specify a penalty and I have been to two competitions and have not incurred a penalty at either (Cypress falls and MIT)
I would use the external battery source as the official source of power to the Arduino as well as all other components for clarity to the supervisor, but seeing as communicating with the Arduino from a laptop would force you to provide it power from your laptop, I don't see a problem assuming your laptop operates at a voltage level below the 14.4V

I think your partner forgot to add 1 point for items in the north zone. Your partner probably thought that items on egg cartons don't receive the 1 pt. even though they do.

@windu34

When does the event supervisor check to see if the arm fits inside 30 x 30 x 100?
Is that after the 3 minutes of test time when the device is powered or before the 3 minutes before the device is powered?

Before. The ES shouldn't let you start your run until your arm is completely within specs. After the run the position/size of the arm is irrelevant (make sure to read the rules on when the timer stops, since if certain parts of your robot fall off or you touch the arm the ES must end the run).

I need some ideas for the production of the master arm (in a master-slave system). I happened to find analog feedback servos from Adafruit, which were a godsend, because they're pretty much potentiometers shaped like servos. That is really great because I can simply mimic the design of the real arm to make the master arm. I'm using the lynxmotion erector kit. However, due to money restrictions, I was not able to purchase a servo to function as the base of the master arm. I am using a good old linear potentiometer for the base, but I'm having trouble on designing the base of the master arm. At home, I have a drill press, a compound miter saw, a circular saw, and a dremel for fabrication. Any ideas?
