Ergonomics Wins: How Cobots Reduce Injuries and Absence

Repetitive strain and awkward postures cause thousands of lost workdays annually. Cobots are now part of the solution, taking over high-strain, low-skill motions — from lifting and twisting to screwdriving and glue application.

Typical Ergonomic Improvements

• Posture relief: Cobots handle overhead or under-bench operations.
• Load reduction: Mechanical assistance for weights above 5 kg.
• Cycle distribution: Shared workflows reduce peak fatigue and microtrauma.

Quantified Benefits

In one Tier-1 supplier, shoulder and wrist injuries dropped 42% within six months of HRC adoption. Absenteeism declined by 15% across assembly lines.

Key Ergonomic Design Practices

• Apply ISO 11228 (manual handling) and ISO/TS 15066 for contact limits.
• Keep operator focus areas below shoulder height.
• Validate workstation reach zones digitally before deployment.
