Robotics!
What is a machine that can sense, act, or perform tasks automatically?
A robot!
What do we call a complete path that electricity can travel through?
A circuit!
What component produces light when electricity flows through it?
A LED
What part makes a bristlebot vibrate and move?
A vibration motor
What do we call a set of instructions that tells a computer or robot what to do?
A program/code
Name one thing a robot might use to detect something around it
A sensor!
Does electricity flow through an open circuit or a closed circuit?
Closed Circuit
What component helps limit the amount of current flowing through an LED?
A resistor
What provides electrical energy to the bristlebot?
Battery
TRUE or FALSE: A computer follows instructions in a specific order.
What part of a robot creates movement?
A motor
What breadboard area is commonly used to connect the positive and negative sides of the battery?
Power Rails
What component can you press to open or close a circuit?
Push button/switch
Why does the bristlebot move when its motor spins?
The off-center motor weight causes vibrations
What is it called when you find and fix a mistake?
Debugging
Why does a robot need a power source?
To provide energy to its components
If an LED doesn't light, name ONE thing you should check.
LED direction, battery, connections, resistor, complete circuit, etc.
What are the small wires used to connect different locations on a breadboard called?
Jumper wires
What might happen if you move the vibration motor to a different position on the bristlebot?
It may move/turn differently
If I tell a robot "move forward, turn right, move forward," does the order of those instructions matter?
Yes
Name two things a robot might need to work.
Battery/power, motor, wires, sensor, controller, etc.
You have a battery, LED, resistor, and button. Put them in an order that creates a working push-to-light circuit.
Battery → button → resistor → LED → battery
What happens if you put an LED into a circuit backwards?
It wont light!
Your bristlebot keeps turning in circles. Name ONE change you could experiment with to make it move differently.
Adjust motor position, battery position, bristles, weight, etc.
A program says repeat 3 times: blink the LED twice. How many times will the LED blink altogether?
