Motors
What body parts do motors resemble?
What connects and powers motors to the hub?
Cables/wires
How do you make a robot turn?
Use a blue motor block.
Are buttons sensors? What sensors?
Yes. Touch sensors.
What motor would be used in this scenario (Large or medium): A SUMMER FAN
A medium motor. (Requires very fast movement)
Wheels are connected to an axle.
What is the axle connected to?
The motor.
What must you do before a movement block?
State the connected cables to the motors.
How does a supersonic sensor measure distance?
High frequency waves being bounced off a surface.
What are the two differences between a large and medium motor?
A large motor is slower and stronger
A medium motor is faster and weaker
What is the brain of the robot called and what is its function?
The brick; stores code which can be used later.
How can a repeat block be used to move a robot in a square?
*HINT* repeat 2 blocks
Repeat a turn and movement 4 times.
How do color sensors determine a color?
By reading reflected light as a value.
What is the difference between a motor and an engine?
An engine relies primarily on combustion/fuel, whilst a motor is powered by a battery.
If more gears are applied to a chain, do they gain or lose power?
They LOSE power.
How does a my-block work?
A set of instructions within one usable block which can easily be repeated.
How would different sources of light affect color sensors?
Brighter sources of light could reflect light differently than other sources.
A wheel and axle uses leverage to reduce what?
*HINT* the word "rub"
Friction
How would gyro sensors affect space travel?
Space debris and gravity would be stabilized by the gyro sensor.
