Generating accurate digital tree models from scanned environments is invaluable for forestry, agricul-ture, and other outdoor industries in tasks such as identifying biomass, fall hazards and traversability, as well as digital applications such as animation and gaming. Existing methods for tree reconstruction rely on feature identification (trunk, crown, etc) to heuristically segment a forest into individual trees and generate a branch structure graph, limiting their application to sparse trees…

From Bioinspiration to Computer Generation: Developments in Autonomous Soft Robot Design
The emerging field of soft robotics presents a new paradigm for robot design in which “precision through rigidity” is replaced by “cognition through compliance.” Lightweight and flexible, soft robots
Topology Optimization and Prototype of a Multimaterial-Like Compliant Finger by Varying the Infill Density in 3D Printing.
TLDR
It is proposed that a multimaterial design can be approximated by varying the values of infill densities in different portions of a 3D-printed component, which enables the multimaterial designs to be prototyped using the general low-cost, single-material fused deposition modeling 3D printing machines.
RayCloudTools: A Concise Interface for Analysis and Manipulation of Ray Clouds
TLDR
The aim is that RayCloudTools is as useful and simple as possible, and the paper is used to demonstrate its utility, and to assess its ease of use, with comparison to established cloud processing libraries.
Point-cloud segmentation of individual trees in complex natural forest scenes based on a trunk-growth method
TLDR
The proposed trunk-growth (TG) method for single-tree point-cloud segmentation applies to many types of trees with various growth shapes, and can effectively identify shrubs and herbs in complex scenes of natural forests.
Heterogeneous Ground and Air Platforms, Homogeneous Sensing: Team CSIRO Data61's Approach to the DARPA Subterranean Challenge
TLDR
The solution developed by Team CSIRO Data61, consisting of CSIRO, Emesent, and Georgia Tech, during the DARPA Subterranean Challenge is described, which enabled a shift in focus from constructing a pervasive communications network to relying on multi-agent autonomy.
Skeleton extraction from point clouds of trees with complex branches via graph contraction
TLDR
A novel contraction method called “graph contraction” to contract 3D tree-shaped point clouds, and an algorithm that can be used to extract a topologically correct skeleton by connecting skeleton nodes is introduced.
AdQSM: A New Method for Estimating Above-Ground Biomass from TLS Point Clouds
TLDR
An accurate and detailed quantitative structure model (AdQSM), which can estimate the AGB of large tropical trees, based on the reconstruction of 3D tree models from terrestrial laser scanning point clouds, is introduced.
Topology optimization of fluidic pressure-loaded structures and compliant mechanisms using the Darcy method
TLDR
A new density-based topology optimization approach using Darcy’s law in conjunction with a drainage term is presented to provide a continuous and consistent treatment of design-dependent fluidic pressure loads.
