Risk Assessment for Human-Robot Collaboration in an automated warehouse scenario

The Effect of Obstacle Design Architectures on Randomly Ranging AGVs in a Shared Workspace

“…The survey also includes pre-collision and post collision methods that have been analyzed by predicting natural human action and motion. Other methods include operator safety on an assembly line for collaborative robots [19], hazard operability analysis to identify the hazards, risk assessment in a human-robot collaborative environment [20], and human-robot interaction guided by operator gesture [21]. In [22], Draganjac, D. Miklic, Z. Kovacic, G. Vasiljevic, and S. Bogdan presented an algorithm for autonomous path planning and motion coordination for multiple AGV's to determine the shortest feasible path by using reliable detection and prioritized conflict resolution in the shared workspace.…”

“…Algorithm (1) is executed to determine the average number of successful steps for various width. Unit Displacement Multiple simulations are carried out for widths ranging from 𝑊𝑊 = [1,20] and at step size, ∆𝑊𝑊, of one unit. Consider three set of workspaces sizes (50 × 50), (75× 75) and (100× 100) unit square.…”

“…Algorithm ( 1) is deployed to study this relationship for various workspaces sizes, including (50×50), (75×75), (100×100), and (125×125) unit square. The simulation is also carried out for width 𝑊𝑊 = [1,20]unit, and at step size, ∆𝑊𝑊, of 1 unit. It can be observed from the results shown in Figure 8.a that the size of the workspace has little significance to the average success.…”

Efficient State Update Exchange in a CPS Environment for Linked Data-based Digital Twins

“…For analysis, we assume the warehouse to have × waypoints along which robots can travel. Furthermore, we assume each robot maintains 2 risk zones (for details regarding the use of risk zones for risk assessment see [25]) within which the actions of other components have to be monitored closely to avoid collision (yellow zone, ) or where corrective action is needed (red zone, ), respectively.…”

Sample-Based Bounds for Coherent Risk Measures: Applications to Policy Synthesis and Verification

“…While there exist a plethora of policy/control generation techniques in a risk-sensitive setting, there exist few verification techniques -especially for arbitrary risk measures -that account for unstructured uncertainty. For example, there are numerous works detailing risk-aware verification procedures for specific systems [21,22,23]. These methods verify their systems of interest against existing widespread standards, e.g.…”
