Frequently Asked Questions
What’s the minimum production volume needed to justify a cobot investment?
Cobots typically require 4-6 hours of daily operation to achieve reasonable ROI, which translates to roughly 1,000-2,000 parts per month for assembly applications. However, ROI depends more on labor cost savings and quality improvements than pure volume. High-value, labor-intensive operations can justify cobots with lower volumes, while simple tasks require higher volumes for economic justification.
How long does it typically take to program a cobot for a new application?
Simple pick-and-place applications can be programmed in 2-4 hours using hand-guiding techniques. More complex applications involving multiple steps, sensors, or quality checks may require 1-3 days. The key advantage of cobots is that basic programming can be done by production operators rather than specialized robotics engineers, reducing deployment time and ongoing costs.
What safety certifications are required for cobot installations?
Cobot safety requirements vary by region but generally follow ISO 15066 for collaborative robots and ISO 10218 for general robot safety. In the US, OSHA guidelines apply, while Europe follows CE marking requirements. Key requirements include risk assessment, safety-rated monitoring, emergency stop capabilities, and operator training documentation. Most cobot manufacturers provide safety certification support.
Can cobots be moved between different production lines or applications?
Yes, mobility is a key cobot advantage. Most cobots can be moved and reprogrammed for different applications within hours or days, compared to weeks or months for traditional industrial robots. This flexibility enables shared usage across multiple product lines and seasonal demand variations. Mobile bases and standardized tool interfaces further enhance portability.
What ongoing maintenance is required for cobot systems?
Cobot maintenance is typically minimal compared to traditional industrial robots. Daily maintenance includes visual inspection and cleaning, weekly maintenance covers basic function checks, and monthly maintenance involves detailed inspection and calibration verification. Annual maintenance may require professional service for bearing replacement and software updates. Total maintenance costs typically run 2-5% of initial investment annually.
