Object-interaction simulation technique for actuated-floor hardware (companion to actuated-floor cluster).

Abstract

Systems and methods to simulate the movement and interaction of objects on modular omnidirectional actuated floors are disclosed herein. A system may include a processor configured to generate a set of particles along a boundary of a contact surface of an object on a modular floor including a plurality of tiles configured to move independently. The processor may also be configured to assign a linear velocity to each particle of the set of particles. The processor may also be configured to assign an angular velocity to each particle of the set of particles. The processor may also be configured to simulate the motion of the object on the modular floor based on the assigned linear and angular velocities. Additional systems and associated methods are also disclosed.

Background

FIELD

The present application relates to systems and methods of simulating the movement and interaction of objects on modular, omnidirectional actuated floors. BACKGROUND

The simulation of the motion and interaction of objects and walking participants on a modular and omnidirectional actuated floor can be difficult and intractable. Such is especially true for large floor sizes and large object and walker counts. This is due to the kinematic, dynamic, and rotational behavior driven by many static and dynamic friction effects, whose effects must be captured precisely to produce realistic behavior.

For example, simulating the motion and interaction of objects on a modular and omnidirectional actuated floor can be difficult due, in part, to the modularity of the floor itself, as each section of the floor can drive objects in contact in different directions, resulting in complex linear and rotational dynamics, which is the result of competing friction effects and the nature of a rigid body. The simulation can also be difficult due, in part, to omnidirectionality, as each floor section can drive different connection points in arbitrary directions and speeds.

To produce realistic and computationally tractable behavior in simulation, cases such as these need to be captured accurately without the need for an explicit model of the friction-based actuation that produces the behavior in reality. BRIEF SUMMARY
