(vii) Coordinate Systems.
Cartesian, polar, and cylindrical coordinates used for robot positioning and movement.
(viii) Specification of Robots.
Resolution: Reference to the smallest incremental movement that a robot can detect or achieve, robot’s control
system and sensors.
Current Trends: Higher Resolution Encoders particularly in applications requiring high precision, such as electronics
or biomedical manufacturing.
Sub-Micron Resolution: High-precision applications, robots, sub-micron levels and semiconductor manufacturing.
Integrated Vision Systems: Integrated vision systems that enhance resolution by allowing real-time adjustments
based on visual feedback.
Accuracy: Ability to position its end-effectors precisely at a desired location.
Current Trends: Enhanced Calibration Techniques- Achieve better absolute accuracy. Calibration accounts for all
joints and links, minimizing errors in each part of the robot arm.
Dynamic Error Compensation: Dynamically adjust for temperature changes, wear, and other environmental
factors to maintain accuracy.
Feedback Mechanisms: Laser-based tracking and real-time correction.
Repeatability: Ability to return to a specific position under identical conditions repeatedly.
Current Trends: Sub-Millimeter Repeatability: Tasks requiring high consistency, such as spot welding in automotive
production.
Improved Mechanical Design: Improved repeatability, as the mechanical components and more reliable over
repeated cycles.
Adaptive Control Systems: Adaptive control systems, complex, repetitive motions, such as pick-and-place
operations in logistics or packaging.
