Study Notes
Robot Programming
- Robot programming is the process of defining a series of basic actions to achieve a specific task or process.
- It involves identifying and specifying the desired motions of the robot so that it can perform them without human intervention.
Definition of Industrial Robot
- An industrial robot is an automatically controlled, freely programmable, multifunctional manipulator with three or more programmable axes.
- It can be used for industrial applications in either a fixed or mobile platform.
Key Concepts
- Degrees of Freedom (DoF): the number of independent movements or rotations of a robot's joints (e.g., q1, q2, q3).
- End-Effector: the end of the robot arm, where the gripper or tool is located.
- Pose: both the position and orientation of the end-point (Pe) in space.
- Base Frame: the fixed frame of reference attached to the base of the robot.
- Configuration: any particular position and orientation of Pe in space.
Robot Programming Methods
- On-Line Programming: uses the robot to generate the program, teaching/guiding the robot through a sequence of motions.
- Off-Line Programming: writes a program using a text-based robot programming language, without needing access to the robot.
- Combination Programming: combines on-line and off-line programming, using on-line to teach locations and off-line to define the task.
On-Line Programming
- Advantage: easy to use, no special programming skills or training required.
- Disadvantages: not practical for large or heavy robots, difficult to achieve high accuracy, and difficult to edit out unwanted operator moves.
Teach-In Process
- Transfer of appropriate programs in the robot controller.
- The robot is manually guided through certain trajectories, and the movements are monitored and stored.
Pose Programming
- Abstract task: specify the position and orientation of the end-point (Pe) in space.
- Uses TCP (Tool Center Point) data, joint coordinates, and world coordinates.
Programming Languages
- Almost every robot has its own programming language.
- Control-independent language: allows programming without needing to understand the robot's internal workings.
Play-Back Programming
- Operator uses the robot to manually perform the task, and the joint angle values are read and stored.
- Requirements: kinematic balance, low friction in joints, and high flexibility of movement.
- Advantages: easy programming, no prior knowledge required.
- Disadvantages: correction in difficult sections, difficult change of velocity.
Task of Sensors
- Used to improve programming ease, flexibility, and versatility.
- Used for searching, tracking, and velocity fitting.
Off-Line Programming
- What is Off-Line Programming? : creating a program without using the robot.
- When? : when the time for teaching in is high compared to production time.
- Why? : to increase productivity, and to optimize and improve programs.
Advantages of Off-Line Programming
-
Programs can be developed without needing the robot.
-
Programs can be optimized and improved.
-
External sensor data can be incorporated.
-
Programs can be tested and evaluated using simulation techniques.
-
Programs can be easily maintained and modified.
-
Programs can be properly documented and commented.### Robot Programming
-
Design and develop a complete robot program and its documentation
-
Test and debug the program using a simulator of the robot and its workspace
-
Test the program on the real robot
Off-Line Programming
- Reduces the cost of teaching a robot
- Is useful in mass production, especially in automotive industry
- Is attractive in small and medium production
- Benefits include:
- Reduction of the robot operating time
- Dislocation of both ends of the danger area of the robot
- Single robot programming system
- Integration of CAD/CAM systems
- Simplification of complex tasks
- Optimization of robot programs
- Access control
- Cycle time analysis
- Verification of robot programs
Types of Robot Programming
- Joint level programming: basic actions are positions and movements of individual joints of the robot arm
- Robot-level programming: basic actions are positions and orientations of the end-effector frame
- High-level programming:
- Object-level programming: basic actions are operations performed on parts or relationships between parts
- Task-level programming: basic actions are complete tasks or subtasks
Examples of Object-Level Programming
- Pick-up part-A by side-A1 and side-A3
- Move part-A to location-2
- Pick-up part-B by side-B1 and side-B3
- Put part-B on-top-off part-A with specific orientation and alignment
Examples of Task-Level Programming
- Paint the car body red
- Assemble the gear-box
