Describe the characteristics of a robot

Automated and Emerging Technologies: Characteristics of a Robot 🤖

1. Physical Characteristics

Robots have a body that can be made of metal, plastic or composites. It includes:

• 🛠️ Actuators – motors or hydraulic systems that move joints.
• 🧱 Structure – chassis, frames, and wheels or legs.
• ⚙️ Power source – batteries, fuel cells or mains electricity.
• 🔋 Energy storage – capacity measured in watt‑hours (Wh).

2. Functional Characteristics

Robots perform tasks by:

1. 🧭 Navigation – moving from point A to B using odometry or GPS.
2. 🔧 Manipulation – picking, placing or assembling objects.
3. 📈 Automation – repeating a sequence without human intervention.
4. 🧪 Adaptation – adjusting behaviour based on sensor input.

3. Cognitive Characteristics

Robots can think by:

• 🤖 Processing data with microcontrollers or embedded CPUs.
• 🧠 Algorithms – path planning, computer vision, and machine learning.
• 📊 Decision making – selecting actions based on goals and constraints.
• 💬 Communication – sending/receiving messages via Wi‑Fi, Bluetooth or radio.

4. Interaction and Sensing

Sensors give a robot its “senses”:

• 👀 Vision – cameras or LIDAR for depth perception.
• 👂 Auditory – microphones for voice commands.
• 👃 Olfactory – chemical sensors in specialized robots.
• 🤚 Touch – force sensors on grippers.

5. Energy and Power

Robots need efficient power management:

1. 🔋 Battery life – measured in hours of operation.
2. ⚡ Energy consumption – watts (W) used by motors and electronics.
3. 🔌 Charging – wired, wireless or solar options.

Example: A Household Cleaning Robot

Take the Roomba as an example: it uses infrared sensors to detect walls, brush motors to sweep, and a battery pack that lasts about 90 minutes. It follows a simple algorithm: move forward → detect obstacle → turn → repeat.

Speed Calculation

The speed of a robot can be calculated with the basic formula:

$v = \frac{d}{t}$

Where $d$ is the distance travelled (in metres) and $t$ is the time (in seconds).
