Big ideas

What does the video mean by, "Programming is Precise"?

• The robot will always move to the precise location you want

• You need to tell the robot precisely what to do, or it might not be what you wanted

• If you do not type the commands exactly as shown, the program will crash

• The robot will do precisely what you want, even if you give it the wrong command

What do Sensors do for a robot?

• Provide power to onboard electronics

• Create a physical effect like turning a wheel

• Processes data and makes decisions

• Give it data on its position and surroundings

What does a robot's Program do?

• Provide power to onboard electronics

• Create a physical effect like turning a wheel

• Process data and make decisions

• Give it data on its position and surroundings

What kinds of Actions can a robot typically take?

• Provide power to onboard electronics

• Create a physical effect like turning a wheel

• Processes data and makes decisions

• Give it data on its surroundings

The hexarotor can maintain its position in the air by monitoring its own motion, calculating whether its position is steady, and adjusting motor power values to make sure it stays in place. This is an example of...

• Sensing

• A program running

• Acting

• All of the above

What kind of Model does the video talk about?

• A "mental model" – a systematic understanding of the way something works

• A design for a LEGO robot "model"

• A tiny "model" version of the real robot

• A "model" who appears in professional photography

What advantage(s) does a "model"-based understanding have over just memorizing facts?

• You can learn a "model" faster than memorizing every single fact

• You can reason about new situations, even ones you haven't seen before

• Models make things make sense

• All of the above

What is the "Program Flow" example in the video a model of?

• Unrelated blocks in the programming software

• Proportional reasoning

• The way a program runs

• Sensing, Planning, and Acting

What does the video mean by, "Break down problems"?

• Split up a big problem into smaller ones that are easier to solve

• Solve the problem all at once

• Give up because the big problem is too hard

• Technical difficulties with the robot

What does the video mean by, "Build up Solutions"?

• Build a fully working solution by expanding upon partial solutions

• The best programs solve every problem at the same time

• Build your robot starting with the wheels and working your way upward

• Accumulate a lot of chemical compounds
