What Are SCARA Robots?
SCARA (Selective Compliance Assembly Robot Arm) robots feature a unique design with rigid vertical movement and compliant horizontal movement. This configuration resembles a human arm with shoulders and elbows that move horizontally while the wrist moves vertically. SCARA robots typically offer:
- Reach ranges: 400-1000mm
- Payload capacities: 1-20kg
- Exceptional precision: ±0.01mm to ±0.02mm repeatability
- Cycle times: 0.3-0.7 seconds for standard operations
Key Advantages in Manufacturing
Speed and Throughput
SCARA robots can achieve 30-40% higher throughput compared to equivalent Cartesian systems, translating directly to increased production capacity without expanding facility footprint.
Precision and Reliability
The rigid Z-axis design eliminates unwanted movement during vertical operations, ensuring consistent results even after millions of cycles—crucial for tasks where precision is non-negotiable.
Space Efficiency
These robots require 30-50% less floor space than comparable systems, with most models needing less than one square meter of installation space.
