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.
