MIT Award-Winning Student Engineering Team Designing & Building NASA Exploration Rovers
NASA HERC Challenge Overview
"HERC is a nine-month long challenge that tasks student teams to design and build human-powered or remote-controlled rovers capable of traversing challenging lunar terrain while completing mission tasks. It is a hands-on, research-based, engineering activity and culminates each year with a final excursion event in Huntsville, Alabama, home of NASA's Marshall Space Flight Center. The activity offers multiple challenges, reaching a broad audience of colleges and universities as well as middle and high school aged students across the world." — NASA
Rover Engineering
We design, fabricate, and test a remote-controlled rover using various engineering solutions, such as CAD modeling, 3D printing, and CNC machining.
Terrain Navigation
We utilize various strategies, such as weight management and debris management to traverse rough terrain. We are unique in our use of treads on our rover, which allows us to traverse rough terrain and inclines with ease.
Science Tasks
After the rover arrives at the task site, we perform simulated science tasks for the mission, including measuring distance and identifying objects.
Engineering Subsystems
Students lead design, fabricate, and test specialized rover systems.
Chassis & Frame
We use lightweight and strong materials like aluminium for the chassis. The chassis is mounted to each tread assembly by two shock absorbers, aiding in suspension.
Drivetrain
On each tread assembly, we use two sprockets, each driven by its own 12V 10:1 motor, to drive the treads. The bottom of the treads are tensioned by four roller wheels which each have their own shock absorbers.
Electronics & Task Completion
We utilize an electronics system organized around a Raspberry Pi. When radio signals are sent by NASA, we receive them, decode them, and respond accordingly. To do so, we can utilize the gimbal-mounted camera to take pictures, or the ToF sensor to measure distance to a target.
