Abstract Selecting the optimal speed for dynamic obstacle avoidance in complex man–machine environments is a challenging problem mobile robots inspecting hazardous gases. Consideration of personal space important, especially relatively narrow such as warehouses and laboratories. In this study, human robot behaviors are analyzed, social force model established to study speed. Four typical behavi...

This paper generalizes the concept of velocity obstacles [3] to obstacles moving along arbitrary trajectories. We introduce the non-linear velocity obstacle, which takes into account the shape, velocity and path curvature of the moving obstacle. The non-linear v-obstacle allows selecting a single avoidance maneuver (if one exists) that avoids any number of obstacles moving on any known trajecto...

Game theorists typically assume that changing a game’s payoff levels—by adding the same constant to, or subtracting it from, all payoffs—should not affect behavior. While this invariance is an implication of the theory when payoffs mirror expected utilities, it is an empirical question when the “payoffs” are actually money amounts. In particular, if individuals treat monetary gains and losses d...
