CAVEMAN

Cave Autonomous Vehicle for Exploration, Mapping, and Navigation

Project Summary:

Led a team of 5 engineers to design and create an autonomous mapping robot for caves/mines to mitigate dangers, built completely from scratch in 4 months.
Caves are inherently dangerous, posing risk to civilians, first responders, explorers, etc. and current cave maps are extremely outdated. We strived to create a solution to all of these problems with CAVEMAN. This rover autonomously navigates caves, maneuvering through the unpredictable terrain, taking pictures of the environment so that it can be turned into a map using our mapping pipeline.
