Problem statement and Objectives

animal researchers are unable to effectively gather data of subterranean species without destroying their burrows or tunnel systems.

Users

Researchers of subterranean animals or underground tunnel systems

Requirements

The robot should be able to:

• Safely and autonomously navigate the specified underground systems
• Map these systems adequately
• Be able to return to the user after completing its tasks

Approach

We approach the problem in a very practical manner, we opt to create a robot that autonomously investigates underground tunnels and maps them. We first make a selection of subterranean animals for which we can map their corresponding burrows, and then research details of these animals and underground systems as to prepare a robot that can safely navigate them

Objectives and milestones

• Make a selection of animals for which it is feasible to construct a robot that navigates their burrows
• Research the animals specified in the first milestone and their corresponding underground systems
• Make a construction plan for a robot that could navigate said tunnels adequately
• Prepare software for path finding in burrowss
• Prepare software for mapping the underground systems
• Construct the robot
• Validate the workings of the robot and summarize our findings

State-of-the-art

A robotics-oriented taxonomy of how ethologists characterize the traversability of animal environments surveys 21 studies of how ethologists characterize the environments through which animals traverse and groups the found characteristics into three broad catergories: local navigational constraints, surface properties, and global layout properties. From these the article makes four recommendations to aid roboticists in selecting a suitable robot for particular environments, building testbeds for the testing and comparing of robots and the collection of data about an environment.

Burrowing rescue robot referring to a mole's shoveling motion proposes an novel inspecting robot designed to inspect survivors at landslide disaster sites. Its proposed propulsion method is inspired by the shoveling motion of a mole.

Deformable Octahedron Burrowing Robot explores the use of a deformable octahedron robot for the autonomous exploration of complex confined spaces. Unlike most other robots, it is able to adapt its shape to better traverse intricate sections of cavities.
