Collaborative Robots

Collaborative robots (cobots) are industrial robots designed to work safely alongside human workers without safety cages. Equipped with force sensors, collision detection, and limited speed/force capabilities, cobots combine automation efficiency with human flexibility, adaptability, and judgment.

Cobot Capabilities

Safe Interaction Built-in safety features including force limiting, collision detection, and immediate stopping protect human workers. Cobots can physically contact humans without injury enabling true collaboration.

Easy Programming Intuitive interfaces including hand-guiding and visual programming enable rapid deployment without specialized robotics expertise. Operators teach tasks by demonstration rather than complex coding.

Flexible Deployment Lightweight, mobile cobots quickly redeploy between applications. This flexibility suits high-mix environments and changing production requirements unsuitable for dedicated automation.

IoT Integration

Performance Monitoring IoT tracking of cobot cycle times, utilization, and task execution reveals optimization opportunities and verifies expected benefits. Data guides deployment decisions and continuous improvement.

Quality Integration Cobots equipped with vision systems and sensors feed quality data into IoT platforms. This integrates cobot operations into comprehensive quality management systems.

Predictive Maintenance Monitoring cobot joint temperatures, motor currents, and cycle counts enables predictive maintenance preventing unexpected failures disrupting production.

Why It Matters

Labor Challenges Manufacturing workforce shortages and repetitive task ergonomic issues make automation essential. Cobots provide automation benefits without massive capital investment or dedicated factories.

Quality Consistency Cobots perform repetitive tasks with perfect consistency eliminating human variation and fatigue. This improves quality while freeing workers for tasks requiring judgment and adaptability.

Flexibility Unlike traditional automation requiring extensive programming and fixturing, cobots adapt quickly to product changes. This enables economical automation in high-mix environments.

Example

An automotive supplier producing electrical harnesses struggles with labor recruitment for repetitive wire insertion tasks. Traditional automation is uneconomical due to 40+ product variations and frequent changes.

The facility deploys three cobots with vision systems performing wire insertion and inspection. CleverIoT monitoring tracks cobot performance showing 99.7% quality consistency versus 96.2% with manual assembly. Cycle time consistency eliminates production variation improving scheduling accuracy.

Cobots redeploy between products in under 30 minutes through visual programming versus multi-week traditional robot programming. Three cobots replace need for six additional production workers (impossible to recruit) while improving quality. Annual value of $320,000 comes from labor savings, quality improvement, and scheduling reliability enabling the supplier to accept business previously declined due to labor constraints.
