Problem Statement

The WVU Robotics team has plateaued in the last several years at 4th place in the RASC-AL Mars Rover competition. Much of the difficulty has come with the communications network that has been used. Our goal is to improve the communications capabilities by adding a stationary base station that will perform all communication needs.


About the Competition

• NASA RASC-AL Exploration Robo-Ops held in Houston, TX

• Mars Rover Prototype – Travers & Collect “Space Rocks”

• Must be Piloted From Morgantown

• Height & Weight Constraints

• The Heaviest Teams Must Go First in the Competition, While Other Teams Can View the Run to Scout Out Scoring Opportunities


WVU Performance History

• 2012: 4th Place Overall – Mechanical Failures

• 2013: 4th Place Overall – Communication Failures


Our Base Station

• Stationary, Begins Beneath the Rover at Starting Location

• Includes 3G/4G Integrated Router, Omnidirectional Antenna, IP Network Camera

• Will Prevent Signal Loss Across Football Field Sized Competition Field

• Carbon Fiber Arm Extends 2 Meters After Rover Moves

• Handles All Data Compression (Lossy)


Base Station Prototype


User Interface

• UI to Provide All Video Feeds from Rover & Base Station

• Pilot has Options for Camera Functionality

• GPS Coordinates of Rocks Provided

• All Aspects & Nodes of Network Accessible through VPN


Communications Network

• All Files Accessible Through Remote VPN

• Files can be Modified Mid-Run by Pilot

• Three Main Nodes: Rover, Pilot, Base Station

• Cellular Communications Links Based on Satellite Communications
