Multiple Choice

How can robots be programmed to perform a series of tasks?

• Only through embedded microprocessors

• Only through manual operator guidance

• Both

• None of the above

Introduction to Robotics in Manufacturing

• Robots are widely used in manufacturing for various tasks.

• They can perform tasks ranging from heavy-duty work to delicate operations.

• Control of robots can be through embedded microprocessors or computer systems.

• Robots can be programmed in different ways.

​Programming Methods for Robots

• Robots can be programmed through sequences of instructions.

• Human operators can manually program robots in two ways.

  • The operator guides the robot arm, and movements are recorded as instructions.

  • The operator wears sensors, and the robot mimics the operator's movements.

• Once programmed, robots can perform tasks identically every time.!

Multiple Choice

Why are robots equipped with sensors?

• To make them more expensive

• To gather information about their surroundings and prevent errors

• To replace human operators

• To make them faster

​Sensors in Robotics

• Robots are equipped with sensors to gather information about their surroundings.

• Sensors help prevent robots from making errors, such as spraying paint without an object to paint or when paint supply is exhausted.

Multiple Choice

What is one advantage of using robots in manufacturing?

• They can handle one-off tasks effectively

• They are immune to unemployment

• They don't require initial setup costs

• They can work in hazardous environments

Advantages of Using Robots in Manufacturing

• Robots are suitable for hazardous environments and can work 24/7.

• They are cost-effective in the long term as they don't require wages.

• Robots offer high productivity and consistency, making products identical.

• They can handle repetitive tasks, freeing humans for more skilled work..

Multiple Choice

What is a potential disadvantage of using robots in manufacturing?

• Increased job opportunities

• Reduced quality control

• Loss of certain human skills

• Lower initial setup and maintenance costs

Disadvantages of Using Robots in Manufacturing

• Robots may struggle with unusual or one-off tasks.

• Automation may lead to unemployment by replacing skilled labor.

• Certain skills, like welding, could be lost due to robot automation.

• Factories can be moved globally, causing employment issues.

Production Line Control with Robots

• Robots are extensively used for production line control in various industries.

• Examples include filling bottles, capping, and labeling.

• Advantages include speed, productivity, consistency, and quality control.

Multiple Choice

How does the computer control the production line with robots?

• Through manual operator guidance

• By using sensors and actuators

• Through magic

• None of the above

Detailed Look at Production Line Control

• The production line uses sensors and actuators.

• Sensors detect bottles and liquid levels, sending signals to the computer.

• The computer controls actuators to open and close valves, move conveyer belts, and maintain the process.

• The process is continuous and efficient

Homework

• Find out about an industrial processes that use production line control.

• In each case, find out the functions of robots at each stage in the process.

• In each case, find the advantages and disadvantages of using robots on the production line

• Be ready to present this next week Monday 30 October 2023
