Why?

The industrial trend is open, fenceless robot systems to allow easy access for humans to the robot cell, to assist and collaborate when desired. However, this poses challenges related to safety, human comfort and operation functionality, that are yet to be solved

Safety Monitoring System (SAM) will fill this functional gap by utilizing state-of-the-art object sensing technology to develop a complete low-cost, add-on system with cutting-edge functions for human safety, comfort and operation.

What?

SAM is a low cost, advanced safety monitoring system providing safe, fenceless, flexible operation of industrial robot systems. It can cover a single robot cell or a factory.

  • SAM Detector detects the human's location and is capable to separate living and artificial objects.
  • SAM Application Module provides actionable safety, user harmony and optimized sharing of tasks and autonomy.
  • SAM Factory Monitoring and Flow Optimization Software monitors and optimizes the work flow in the entire facility.

In Brief

  • SAM4ROB is a research project, funded by Eurostars, which aims to offer a Safe Area Monitoring (SAM) robot system for fenceless factory automation.
  • The goal for SAM is to provide a natural, safe, synergic coexistence and collaboration between humans and robots even in harsh industrial environment
  • SAM4ROB Consortium :
    - 4 SMEs (PPM Robotics AS, YUJIN Mechatronics, DLM Solutions and F&P Robotics AG)
    - 2 Research Institutions (DGIST, BME)

Safety approaches

Contact based
  • Soft robot surface
  • Soft compliant robots
  • Hard stop
Reactive
  • Warnings when Human is in danger
  • Reduce motion speed
  • Change motion direction
  • Change internal robot arm configuration (utilize redundant kinematics)
Proactive
  • Warnings about potential danger
  • Rescheduling the task
  • Dynamic configuration of the robot’s permitted working area (reconfiguring the safety zones)
  • Proactive augmentation of robot path
Preventive
  • Warnings about possible danger nearby to avoid the risk for Human interference
  • Warnings about a potential threat in moving into interference zones)
  • Reduction of the robot’s motion speed (fear reduction)
  • None

Functionalities

Safety
Effective with emergency-stop, reactive safety and proactive safety actions

Avoidance of potential conflicts between the human and the robot. Today, no other safety concepts offer proactive functionality

Comfort
Communication of the robot’s intended actions

Make the human continuously updated and comfortable when he is inside the robot's working area.

Collaboration
Task optimization

Task-based optimization of shared human and robot collaboration, and automatic workflow optimization based upon the human's location

Operation
Add-on functionality for robot programming assistance

Automatically generating collision free paths and device tool positioning, based upon the data from SAM Detector Module.

Factory
Process optimization

Monitoring and optimizing work flow control of the productions cells

Features

Reduced floor space

With long range detection of moving objects we discover potential conflicts early, and thus, don't require the normal, extra safety margins for robot cells.

Increased flexibility

On demand configuration of the robots' safety zones and safety modes.

On demand switching between automatic, co-located and collaborative mode

Increased comfort

Notification about potential conflicts can reduce the stress caused by unnecessary emergency stops. Robots have “social skills” to make them less scary.

Increased productivity

Open robot systems can work at full speed, when people are not in danger.

Proactive conflict solving increases the up-time of the robot cells.

Increased comfort and productivity by proactive means
Early moving object detection
  • Predict objects’ intended action
  • Distinguish between humans and inanimate objects
Proactive conflict avoidance
  • Determine potential conflicts
  • Conflict reduction with pre-notification of the user
Humans and robots in harmony
  • Robots with artificial, social skills
  • Automatic task selection for co-existing and collaborative work
