Painting Robot Selection Guide
Selecting the right painting robot is critical for project success. This guide provides a systematic approach covering key specifications, brand comparisons, application recommendations, and cost analysis for informed decision-making.
Key Selection Parameters
Work Envelope
Match robot reach to your largest workpiece. Consider 7-axis robots for complex geometries and internal surfaces.
Tip: Add 10-15% margin for tooling and approach angles
Payload Capacity
Calculate total load: atomizer weight + paint hose + cable bundle + safety margin. Painting robots typically need 5-15 kg payload.
Tip: Hollow wrist robots carry less but offer better hose routing
Repeatability
Painting requires ±0.2mm or better for consistent film thickness. Higher precision robots justify cost in quality-critical applications.
Tip: Consider thermal expansion in high-temperature booths
Environment Rating
Paint robots must be IP67 or better. Foundry Plus (IP67) for wet booths, Clean Room versions for sensitive coatings.
Tip: ATEX certification required for Zone 1 explosive atmospheres
Axis Configuration
6-axis standard for most applications. 7-axis (linear rail) for extended reach. Consider wall-mount or inverted for space optimization.
Tip: 7th axis enables larger work envelope without larger robot
Integration Features
Paint-specific software (paint path generation), hollow wrist design, integrated paint supply, explosion-proof certification.
Tip: Check availability of painting-specific software options

Cost Optimization Tips
- Naked robot: Right-size to avoid overspecification
- Used equipment: Consider refurbished robots for lower initial cost
- Framework agreements: Negotiate volume discounts for multiple units
- Spare parts: Rational inventory to avoid overstocking
- Domestic alternatives: Evaluate local brands where suitable
