What is the University Rover Challenge (URC)?
According to URC: The University Rover Challenge (URC) is the world's premier robotics competition for college students. Held annually in the desert of southern Utah in the United States, URC challenges student teams to design and build the next generation of Mars rovers that will one day work alongside astronauts exploring the Red Planet.
URC according to me: A fantastic excuse to build kick ass robots, solve complex problems, learn new things, and generally do what I love with my friends
Extreme Retrieval and Delivery
We need to:
Operate various knobs, buttons, switches etc on the lander
Type a specific phrase on the keyboard
Pick up a “cache” weighing in at 5kg, and place it in a drawer
Design Philosophy
Design for Utah, not Mars
Commit to designs as early as possible, especially if they affect other systems
The best part is no part
If it can be off the shelf, it should be off the shelf
Delete CNC, embrace sheet metal
Solve problems with money instead of time if possible
Make it pretty
Why did I adopt these?
… my experience at SpaceX
Basically, the rover needs to:
Navigate rough terrain such as hills, rocks, sand, etc
Pick up both small rocks ~.5” diameter and large rocks ~5” diameter
Pick up various other crap
Open tool boxes, latched boxes etc
Operate up to 2km away
Equipment Servicing
Design Requirements and Nice to Haves
Overall:
Commit to a design as as fast as possible (months before other subteams)
Start build as fast as possible
Near zero machined parts
Start build during first semester
Make it pretty
Frame:
Committed to as early as possible
Dedicated mounting for all systems
Sheet metal
Internal wiring
Modular–ability to accommodate design changes
Suspension:
Capable of rough terrain
Damped
Easy to manufacture
Maximize wheelbase
4 wheels
Not rocker bogie
Wheels:
Capable of rough terrain
High grip
Off the shelf tires
Easy
Swerve???
Fast (3x faster ~12mph)
