BEAST

Project details

Programme
Research Cluster RC3

Contemporary knowledge workers in the 21st century are becoming increasingly global and nomadic leading to feelings of social separation and loneliness. In reaction to this, BEAST is designed as an autonomous spatial entity which interacts with the changing social and natural conditions of its environment to catalyse new playful social spaces. The body plans of BEAST extend the characteristics of scissor structures and are composed of linkages of various tensile and compression components with passive and active joints enabling them to maximise degrees of adaptation while minimising actuation. BEAST is a cyber-physical system made self-aware through a lidar sensory system and through motor sensor feedback, evolving its self-adapting behaviour in relation to its changing human and non-human environment. The research involves parallel development and integration of robotic prototypes with sensor actuation control systems, and a Unity-based simulator using reinforcement learning to learn adaptive policies for mobility, spatial configuration, and shading. Throughout the course each day BEAST senses its internal structural state in relation to the location and movements of people and the sun, continuously adjusting its configuration in a dynamic balance to provide evolving social spaces.

Geometric Principle of Component Connection

The connection between the prototypes is represented in detail with geometric diagrams to complete the 2D to 3D conversion.

Component Cluster with Different Prototypes

Bounding Boxes for Components and Clusters

The bounding box is used instead of the rod, and a reasonable connection form is selected. Rods are connected from Component to Component Cluster and finally to BEAST.

BEAST Library

The library of BEAST's rods and bounding boxes.

BEAST on Different Environment

Different functions of different scales of BEAST combined transformation in different environments.

BEAST Body, Robotic Research

BEAST Body, Robotic Research

Component Library

Develop joint systems of different generations through experiments to cope with diversified morphological changes.

The Linkage of Scissor Structure

The Linkage of Scissor Structure

The entire structure is deformed by rotating a single joint.

BEAST Movement

BEAST Movement

Beast body plans are composed of linkages of various components with passive and active joints enabling them to maximise degrees of adaptation while minimising actuation.

Self-Aware BEAST

Self-Aware BEAST

Beast is self-aware through a lidar sensory system and through motor sensor feedback, evolving its self-adapting behaviour in relation to its changing human and non-human environment.

BEAST 02

The BEAST 02 is composed of 3 kinds of components and 66 rods, and it is equipped with LiDAR sensor system to become a self-aware BEAST.

BEAST Behaviour, Reinforcement Learning

Basic Elements Testing

Basic Elements Testing

Simulations of the five basic elements, as well as tests of their variations.

Simulation Test and Classification of Prefabrications

Simulation Test and Classification of Prefabrications

The geometry analysed in the previous stage was set up in a virtual environment, and gravity, material collision and external force were added.

BEAST 03 Training Report

BEAST 03 Training Report

BEAST 03 training parameters and a comparison of pre-training and post-training behaviour.

Training Reports on Reinforcement Learning

Training Reports on Reinforcement Learning

From Component evolution to BEAST reinforcement training reports, environment settings, training rewards, and agent learning are all shown in the reports.

Behaviour Before and After Reinforcement Learning

Behaviour Before and After Reinforcement Learning

The movement record of the agent. As the composition of components increases, the movement ability of the agent becomes more complex.
