Trivia
What programming language do we use?
What is an integer?
A number that can be positive, negative, zero, and does not include any decimals or fractions.
A robot needs to move to a target. It can move forward, backward, left, or right. What information does it need to know to determine which direction to move?
Its current position and the target's position.
A robot can only follow instructions you've given it. True or false?
True
What is our team number?
5124
What is the distance formula?
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
robot follows these rules: If the target is more than 10 feet away, drive forward. If it is less than 10 feet away, slow down. If it is less than 2 feetaway, stop. The robot is 1.5 feet away. What should it do?
Stop
A robot keeps turning left forever. What is the most likely problem:
A. The robot hates right turns
B. Its instructions never tell it to stop turning
C. Its battery is too full
B
What does FRC stand for?
First Robotics Competition
What is a vector?
A quantity with both a magnitude and direction.
A robot has three possible paths to a target. Path A is 8 feet, Path B is 12 feet, and Path C is 6 feet. The robot cannot use Path C because of an obstacle. The robot also cannot turn around while moving. What information would the robot need to determine the fastest remaining path?
How fast it can travel along each path / the time required for each path.
Which of these instructions would be easiest for a computer to understand?
A. "Go over there."
B. "Move forward a little."
C. "Move forward 10 feet."
D. "Go that way."
C
How many teams play in a FRC match?
3v3, 6 total.
What do sine, cosine, and tangent help you calculate?
Relationships between angles and sides of a triangle.
The robot can face North, East, South, or West. It can only turn in 90° increments. If the robot is currently facing one direction and needs to face another, how can you determine whether it should turn left or right to reach its new direction using the fewest turns?
There are many answers. Possible solution: Calculate the number of 90° turns in both directions and choose the direction requiring fewer turns.
The robot has the following instructions: If the light is red, stop. If it's green, go.
The light is yellow. What happens?
Nothing.
Is "yurp" a frog sound?
YES!!!!!
How many degrees is one radian?
180/pi (we usually use radians because they work better with trig functions)
Easier than it sounds: Our robot needs to know how fast to shoot to make it into the target based on how far away it is, how do you figure out the correct speed?
Instead of calculating the speed with a formula, we record the tested distances and their corresponding speeds. (this is what we actually use on our robot)
There are three switches:
A, B, and C
and three lights:
Red, Green, Blue
Each switch controls exactly one light.
You know:
Switch A does not control Red.
Switch B controls either Red or Blue.
Switch C does not control Blue.
Switch A and Switch C control different colors.
Which switch controls which light?
A = Blue, B = Red, C = Green.
