Small rover that autonomously follows forest paths 🚗🏕

Autonomously Following Forest Paths with a Mobile Robot using Semantic Segmentation

Website: pathy.pfiers.net

This project is Pieter Fiers and Simon Germeau's professional bachelor's thesis for UCLL's Aplied Informatics degree.

We created a rover that is capable of autonomously following forest paths.

We used a Semantic Segmentation CNN, as opposed to the classification CNN used by Giusti et al.¹ and Smolyanskiy et al.². We believe this enables interesting future expansions, like higher-level decision making about path intersections, and the mapping of road geometries.

Repository structure

The repository is structured according to the four main stages of our project:

Dataprep - Documentation about, and the scripts we used for, the processing and labelling of data used for training.

Model - This folder contains the machine learning process we used to train our CNN.

Rover - Documentation regarding the hardware aspect of our rover.

ROS - All documentation, ROS (Robot Operating System) nodes, and extra files needed to make the rover drive itself.
