    Study Notes

    Industrial Robot Purpose

    • The primary purpose of an industrial robot is to automate tasks that are hazardous, repetitive, or difficult for humans to perform
    • This includes tasks like welding, painting, assembly, material handling, and packaging

    Industrial Robot Degrees of Freedom

    • The typical number of degrees of freedom in an industrial robot is six
    • This allows for movement in all three dimensions (x, y, z), as well as rotation around all three axes (roll, pitch, yaw)

    Robot Joint Type

    • A revolute joint allows motion along a circular arc between two links

    Robot Configuration

    • A robot with all three joints as prismatic is called a Cartesian robot

    Workspace Definition

    • The workspace is the volume of space reachable by the end-effector mount of a robot

    Robot Categorization

    • The first three joint types in categorizing industrial robots are prismatic, revolute, and cylindrical,
    • These types establish the robot's fundamental movement capabilities, determining the shape and extent of its workspace.

    Cartesian Workspace

    • A Cartesian workspace is rectangular or cubical

    Cartesian Robot Disadvantage

    • A Cartesian robot has a limited reach and can be expensive and complex to design

    Cylindrical Configuration

    • A cylindrical robot has one prismatic joint and two revolute joints

    Cylindrical Robot Advantage

    • A cylindrical robot has a larger workspace than a Cartesian robot

    Spherical Workspace

    • A spherical workspace is spherical.

    Spherical Robot Disadvantage

    • A spherical robot is not ideal for reaching into confined spaces, due to its limited workspace.

    Anthropomorphic Robot Configuration

    • An anthropomorphic robot has three revolute joints, allowing for rotation around all three axes

    Anthropomorphic Robot Advantage

    • An anthropomorphic robot is highly dexterous and versatile due to its human-like structure

    KR 1000 Titan

    • The KR 1000 titan, is a large and powerful anthropomorphic robot, capable of lifting heavy payloads

    Anthropomorphic Robot Disadvantage

    • Anthropomorphic robots can be expensive and complex to maintain
