What is Robotics?

**Robotics** is the principle of a robot carrying out a task by following a precise set of programmed instructions.
Robots can be categorised into **dumb robots** (repeat same instructions, no AI) and **smart robots** (adapt and learn using AI).
Example of dumb robot: car assembly line robot.
Example of smart robot: assisting surgeons in delicate procedures.
Development of AI, machine learning and robotics raises ethical/legal issues: **accountability**, **safety**, **algorithmic bias**, **legal liability**.

Characteristics of a Robot

All robots share three common characteristics: **mechanical structure**, **electrical components**, and being **programmable**.
**Mechanical structure**: a physical body that can move and interact with the environment.
**Electrical components**: sensors, microprocessors and actuators.
**Programmable**: designed to follow a precise set of instructions.

Role of Robots – Industry

**Quality inspector**: uses advanced vision to inspect products for defects, improving quality control.
Advantage: consistent inspection, reduces human error.
Disadvantage: may not work on defects requiring human judgement.

Role of Robots – Transport

**Warehouse worker**: efficiency in finding, moving and packing items; less reliance on manual labour.
Advantage: increased efficiency and productivity.
Disadvantage: high infrastructure costs and potential safety concerns for human workers sharing the same space.

Role of Robots – Agriculture

**Planting & seeding machine**: precise planting at optimum depths and distances.
Advantage: improves crop yield and reduces waste.
Disadvantage: high upfront costs, may struggle with uneven terrain and changing weather conditions.

Role of Robots – Medicine

**Rehabilitation therapist**: provides personalised physical therapy exercises to aid recovery.
Advantage: consistent, tailored therapy sessions.
Disadvantage: does not provide emotional support.

Role of Robots – Domestic & Entertainment

**Sous chef**: assists with meal prep (chopping, measuring, following basic recipes).
Advantage: saves time and effort in the kitchen.
Disadvantage: limited ability and capabilities.
**Educational robot**: provides interactive learning experiences for children, increasing engagement.
Advantage: engaging and interactive learning.
Disadvantage: high cost, cannot replace human teachers.

Advantages & Disadvantages of Using Robots

Advantages to employees: no need to lift heavy items, protected from dangerous tasks, can utilise skills in other tasks, no repetitive/mundane tasks.
Disadvantages to owners: expensive to install/purchase/setup, high ongoing maintenance costs, may deskill workforce, production may stop if malfunction.

Three key characteristics of a robot: mechanical structure, electrical components, and programmability.
