Robotics in Industry: Study Notes
Introduction
Industrial robotics refers to the use of programmable machines (robots) to perform manufacturing, assembly, packaging, and material handling tasks. These robots are designed to increase efficiency, precision, and safety in industrial environments. The field integrates mechanical engineering, electronics, computer science, and artificial intelligence.
Historical Overview
- 1961: The first industrial robot, Unimate, was installed at a General Motors plant.
- 1970s–1980s: Rapid adoption in automotive and electronics industries.
- 2000s–present: Integration of AI, machine learning, and advanced sensors.
Core Components of Industrial Robots
- Manipulator (Arm): Provides movement in multiple axes.
- End-Effector: Tool attached to the arm (e.g., gripper, welder).
- Actuators: Motors or hydraulic systems powering movement.
- Sensors: Enable feedback and precision.
- Controller: Computer system for programming and operation.
Types of Industrial Robots
Type | Description | Common Uses |
---|---|---|
Articulated | Rotating joints (2–10 axes) | Welding, painting, assembly |
SCARA | Horizontal movement, vertical | Pick-and-place, assembly |
Cartesian | Linear movement (X, Y, Z axes) | CNC machines, 3D printing |
Delta | Parallel arms, high speed | Packaging, sorting |
Collaborative | Safe for human interaction | Shared workspaces |
Key Equations
1. Forward Kinematics
Describes the position and orientation of the robot’s end-effector:
Equation:
[X, Y, Z] = f(θ1, θ2, ..., θn)
Where θn are the joint angles.
2. Inverse Kinematics
Calculates joint parameters for a desired end-effector position:
Equation:
θn = f⁻¹(X, Y, Z)
3. Velocity and Acceleration
For joint i:
Velocity:
v_i = dθ_i/dt
Acceleration:
a_i = d²θ_i/dt²
