Introduction

Problem statement

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.

Evolving Sparse Direction Maps for Maze Pathfinding This paper focuses on evolving data that allows an entity to reach a point quickly from any other point in the maze. This kind of map is generated by a simple genetic algorithm. But this method did not necessarily give the shortest path.

View-Based Cognitive Mapping and Path Planning A view graph is created where views are seen as nodes and the movement between views are seen as edges. This graph retains the topological and directional structure of the maze. A neural network can learn the view graph during a random exploration which then allows it to generate expectations about which views will be encountered next.

Design and Implementation of a Path Finding Robot Using Flood Fill Algorithm This article tries to find out how effective the flood fill algorithm is for maze solving. This algorithm was implemented in a small robot with ultrasonic range sensor and wheel rotation decoders. The robot was able to map the maze and afterwards would do a second run where it tried to find a shortest route to the goal.

Solving a Reconfigurable Maze using Hybrid Wall Follower Algorithm This paper expands on the wall follower method of solving a maze, the new algorithm combines left and right hand rules and tests them on several mazes. This hybrid algorithm improved the maze solving abilities significantly compared to just following the wall.
