Overview

This document presents detailed technical specifications and comparisons of various KUKA industrial robotic models and linear units. It covers key performance parameters such as payload capacity, reach, repeatability, weight, mounting options, axis movements, speeds, and special features tailored for diverse industrial applications.

1. Payload Capacity

Robots range from lightweight models handling as little as 3 kg to heavy-duty units supporting payloads up to 6500 kg. Smaller robots like KR 6-2 and KR CYBERTECH nano manage payloads around 6 kg, while large-scale models such as KR 1000 titan PA and KR 1300 titan PA handle payloads up to 1300 kg, with some models extending to 6500 kg.

2. Reach and Dimensions

Reach varies widely, from compact robots with approximately 541 mm reach to large robots exceeding 3700 mm, and linear units extending reach up to 30 meters depending on configuration. For example, KR 6-2 has a reach of about 1611 mm, while KR 1000 titan PA reaches 3195 mm. These dimensions influence the suitability for specific tasks and workspace requirements.

3. Repeatability and Accuracy

Precision is critical, with repeatability values ranging from <±0.02 mm for highly accurate small robots to <±0.15 mm for larger models. Most robots maintain repeatability within <±0.05 mm to <±0.10 mm, ensuring reliable performance in precision manufacturing and assembly.

4. Robot Weight

Robot weights vary significantly, from lightweight units around 23.9 kg to heavy models exceeding 4700 kg. For instance, KR 6-2 weighs approximately 235 kg, whereas KR 1000 titan PA weighs about 4740 kg. Weight impacts installation, mobility, and structural support requirements.

5. Mounting Options

Mounting flexibility includes Wall, Floor, Ceiling, and Angle mounting. Some models support multiple mounting types, enhancing adaptability to various industrial environments. For example, KR 6-2 supports all four mounting types, while KR QUANTEC prime primarily supports Floor and Ceiling mounting.

6. Axis Movement and Rotation Ranges

Robots typically have 6 or 7 axes, with rotational ranges between ±114° and ±350°, and some axes offering infinite rotation. These ranges define the robot’s maneuverability and workspace coverage, critical for complex tasks.

7. Axis Speeds

Axis speeds vary from 45°/s up to 789°/s. Smaller, faster robots achieve higher speeds, improving cycle times, while larger robots operate at slower speeds (50°/s to 200°/s) suitable for heavy payload handling.

8. Special Features and Applications

• Models optimized for arc welding and other specialized industrial processes.
• High-accuracy robots designed for precision manufacturing.
• Variants suitable for cleanroom environments, foundry conditions, splash-proof applications, food industry hygiene, and explosive atmospheres.

9. Product Range and Types

The document covers a broad product range including LBR iiwa, KR series (KR 3 to KR 4000), AGILUS, fivve, sixx, and linear units (KL series). Payloads range from 3 kg to 6500 kg, with reach and axis configurations tailored to diverse industrial needs.

10. Additional Notes and Recommendations

• Select robots based on payload and reach to optimize performance and cost-efficiency.
• Consider repeatability and accuracy for tasks requiring precision.
• Choose mounting options compatible with the installation environment.
• Ensure axis speed and rotation ranges meet operational cycle time and workspace demands.
• Use specialized models for arc welding, cleanroom, or harsh industrial conditions as appropriate.
