Getting Started:
Have
all the students sign in
If
students from the other group show up, let them stay
Assembly and Power:
Is
the robot built as desired? (check for loose/missing parts)
Are
the motors wired to the ÒbrainÓ using ports B, C, or A?
(if not, motors wonÕt move)
Are
the sensors wired to the ÒbrainÓ using ports 1,2,3,4?
(if not, sensor wonÕt work)
Is
the battery attached, and does the robot Òturn onÓ?
(if not, get new battery)
Programming:
Is
the program as simple as possible?
It is best to test
changes in small steps
Motors:
Check each of the options carefully; is it what you want?
Motors:
Are the motor commands using the right ports? (A,B,C)
Downloading programs to the robot:
Is
the robot connected to the computer via the USB cable?
Is
the robot on?
Did
the program download to the robot?
Sometimes
the robotÕs memory fills up. Empty it by
pushing
the memory button near the ÒdownloadÓ button

returned for recharging.)
Is the USB cord back in the kit?
