Team Vision for Problem Definition Phase

During the Problem Definition Phase, we sought to organize ourselves, by assigning team roles, solidifying our vision for the overarching project, and performing extensive background research, to reduce backtracking and delays down the road. We successfully managed to achieve these goals, although we continue to research background information related to our project to improve our capacity to design and prototype in the coming project phases.

Project Summary

The purpose of this project is to create a device that can both walk on land and swim through water. The project is based off previous RIT projects, specifically the Robo-ant and Robo-fish. Essentially this project is meant to combine the two projects to create an amphibious robot otter.

Few amphibious robots today tend to have full integration between terrestrial and aquatic locomotion, as is the case with biological organisms capable of amphibious ambulation. Furthermore, these tend to lack agility and flexibility, and can thus not perform complex maneuvers while moving. One robot which does achieve pseudo-biological performance in this way is the “Pleurobot”, a research platform designed to mimic the physiological behavior of a salamander, however this only has planar freedom of motion while swimming.

Use Scenario

In the long term, this project could have multiple real-world uses in military and research applications. Below is an example of a research use scenario:

Project Goals and Key Deliverables

The goal of this project is to design an amphibious robot which can mimic the movements of otters both in and out of water. The final product should be able to swim at the surface of water, walk on land, and transition between land and water. The expected result is a functional prototype with systems that can ultimately be used in other devices for military, investigation, and research purposes in the future.
