Robotics (Liam) Flashcards
(40 cards)
What is robotics?
Robotics is the branch of technology that deals with designing, building, and programming robots to perform tasks.
What is the Internet of Things (IoT)?
IoT refers to a network of physical devices connected to the internet, which collect and exchange data.
Give one real-life example of IoT.
A smart fridge that tells you when you’re low on milk.
What is the key difference between a human and a computer?
Humans think and feel, while computers follow programmed instructions.
What is a variable in programming?
A variable is a storage location in a program that holds a value which can change.
What does a formula in coding represent?
A formula is an expression that performs a calculation or action in a program.
What is the function of the ‘+’ operator?
It adds two values.
What does the ‘AND’ condition do in programming?
It returns true only if both conditions are true.
What does the ‘OR’ condition do?
It returns true if at least one condition is true.
What is a servo motor?
A servo motor is a motor that moves to a specific angle, controlled by code.
How does the Micro:bit control a servo motor?
By sending PWM (Pulse Width Modulation) signals to change the angle.
What is the difference between analogue and digital signals?
Analogue signals vary continuously; digital signals are either on or off (1 or 0).
Give an example of an analogue device.
A dimmer switch for lights.
Give an example of a digital device.
A light switch that is either on or off.
What is a breakout board?
A board that allows easy access to the pins of a microcontroller or chip.
Why is correct power supply important in a circuit?
To prevent damage to components and ensure they work properly.
What is Tinkercad and what is its primary purpose?
Tinkercad is a free, web-based 3D design and modeling application that allows users to create 3D designs using simple building blocks. Its primary purpose is to help beginners learn 3D design and prepare models for 3D printing.
Name two main categories of tools available in Tinkercad.
- Basic shapes (geometric primitives like cubes, spheres, cylinders)
- Electronics components (for circuit simulation)
List five basic operations you can perform on objects in Tinkercad.
- Move/translate objects
- Rotate objects
- Scale/resize objects
- Group objects together
- Create holes (subtract objects)
Explain what a ‘hole’ object does in Tinkercad.
A ‘hole’ object in Tinkercad is used to subtract material from solid objects, creating hollow spaces or cutouts. Example: Creating a hole in a cube to make a container or box.
What file format does Tinkercad typically export for 3D printing?
STL (STereoLithography) format
Define robotics.
Robotics is the field of technology that deals with the design, construction, programming, and operation of robots to perform tasks automatically or with human guidance.
Define Internet of Things (IoT).
Internet of Things (IoT) refers to a network of physical devices embedded with sensors, software, and connectivity that enables them to collect and exchange data over the internet.
List four key differences between humans and computers.
- Humans can think creatively and adapt; computers follow programmed instructions
- Humans have emotions and intuition; computers process data logically
- Humans can learn from experience naturally; computers need to be programmed to learn
- Humans can handle ambiguous situations; computers need precise, clear instructions
