Occupational Safety Training for Operating Robot Arms

1. Overview of Robot Arms

a. What is a Robot Arm?

A robot arm is an automated device shaped and functioning similarly to a human arm but designed to perform automatic or semi-automatic tasks in industrial or research environments. Robot arms are commonly used in various applications, from assembly and material handling on production lines to performing precise surgeries in the medical field.

Main Components of a Robot Arm

• Links and Joints: A robot arm typically consists of connected segments that can move in different directions. The joints can be rotary joints or prismatic joints, allowing flexible movements.
• Motors and Control System: Motors control the arm’s movements by adjusting the position and angles of the joints. The control system manages sensor signals and executes commands to operate the arm.
• Sensors: Sensors help the robot arm perceive its surroundings and operating status. They can measure force, position, and other parameters essential for precise control.
• End Effectors: The end part of the robot arm, called grippers or attached tools, performs specific tasks such as gripping, assembling, welding, or surgery.

b. Operating Principle of Robot Arms

Input

The robot arm starts by receiving information from control sources, which may come from:

• Operator: Commands entered via control panels, computers, or remote control devices.
• Sensors: Sensors mounted on the robot arm provide data about position, applied force, or the environment.

Signal Processing

Input signals are sent to the robot arm’s control system, which typically includes:

• Controller: The controller analyzes inputs and determines necessary actions. It may be a microprocessor or digital signal processor (DSP) running pre-programmed control software.
• Control Algorithms: Algorithms such as PID (Proportional-Integral-Derivative) adjust signals to achieve precise position and force.

Motion Control

After processing, the control system sends commands to the arm’s moving parts:

• Motors: Motors execute the required movements, adjusting joint positions. These can be stepper motors, servo motors, or DC motors.
• Actuators: Actuators transmit motion from motors to joints and links of the robot arm.

Kinematic Motion

• Kinematics: Study of joint and link motion without considering forces. The robot arm uses kinematic equations to calculate necessary movements to reach desired positions.
• Inverse Kinematics: Sometimes used to calculate joint angles needed to place the tool at a specific location.

Task Execution

Once positioned accurately, the robot arm performs programmed tasks, which may include:

• Gripping and Material Handling: Using tools or grippers to pick up, move, or assemble materials.
• Surgery or Research: Performing precise tasks in medical or research environments.

Feedback and Adjustment

• Feedback Sensors: Continuously monitor the robot arm’s status, providing feedback on position, force, and other parameters.
• Adjustment: Based on feedback, the control system adjusts commands to ensure accurate task performance.

Interaction and Automation

• Human Interaction: Some robot arms are designed to interact directly with humans, featuring safety mechanisms and human-machine interfaces.
• Automation: Robot arms can operate fully automatically, performing repetitive cycles without human intervention.

c. Industries Using Robot Arms

b. Training Duration

Initial Safety Training Duration

• Total training time must be at least 24 hours, including examination time.
• 8 hours of theory on occupational safety policies and laws
• 8 hours of theory on basic occupational safety knowledge
• 4 hours of theory on specialized training content
• 2 hours of practical training on specialized content
• 2 hours of final theoretical exam

The safety training center will schedule multiple sessions depending on workers’ availability. Usually, there are 6 training sessions over 3 days, provided the manufacturing enterprise can arrange continuous training time.

Periodic Safety Training Duration

• Before the occupational safety card expires, workers who wish to renew must attend periodic occupational safety training with a training duration of at least 50% of the initial training duration.

Explanation: the total periodic occupational safety training time must be at least 12 hours, including examination time. After successfully completing the periodic training and passing the exam, workers will be reissued or have their occupational safety card extended.

c. Training Content

d. Occupational Safety Card

After completing the occupational safety training and passing the examination, workers will be issued an occupational safety card (commonly called the occupational safety certificate for Group 3).

The Group 3 safety card clearly shows information such as full name, date of birth, specific job and working environment, training duration, official stamp, and signature confirming completion of the training course.

According to regulations on card issuance stated in Clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:

• If the employer and employee have a labor contract, the employer must stamp and endorse the safety card after the employee completes training and passes the exam.
• If the worker is freelance or temporary and does not have a labor contract, the training unit must stamp and endorse the safety card after training and passing the exam.

3. Hazards for Workers When Operating Robot Arms

Collision and Physical Injury

• Collision risk: Robot arms can move quickly and powerfully, posing dangers if they collide with workers or other objects in the work area.
