About the Project
Motivation
JPL is always looking to inspire the next generation of scientists, engineers, and roboticists to help us explore and learn about our solar system (and beyond!). We release the plans for this
Specifications & Technical Attributes
The specific attributes of the robot you build will depend slightly on the type of electronics and motors you buy for the system. The numbers shown below are for the version of the robot that contains exactly the parts that we suggest in our build documents and parts list. Below, you can see which parts could be changed for which spec upgrades.
| Attribute | Value [imperial] | Value [SI] |
|---|---|---|
| Weight | 25 [lbs] | 11.34[kg] |
| Footprint | 24x14 [in] | 60.96x30.48 [cm] |
| Battery Capacity | 5200 [mAh] | 5200 [mAh] |
| Battery Discharge Rate | 8 [A] | 8 [A] |
| Nominal Current Draw | 1.2 [A] | 1.2 [A] |
| Operating time | 5 [hrs] (continual use) | 5 [hrs] (continual use) |
| Approximate Max speed | 9.7 [in/s] | 24.6 [cm/s] |
| Maximum 90 deg vertical scale | 12 [in] | 30.48 [cm] |
| Maximum height differential between sides | 14 [in] | 35.56 [cm] |
| Communication (in this guide) | Bluetooth app (Android only) and Xbox Controller |
Features
This rover is designed to function similarly to the 6 wheel rover designs on Mars and employs a few of the major driving mechanics that the Mars rovers use to traverse rocky surfaces:
- Rocker-Bogie: The Rocker-Bogie suspension system allows all 6 wheels to continually be in contact with the ground while climbing over obstacles
- Differential Pivot: Allows the weight to be mechanically offloaded from one side of the rover to the other while climbing
- 6-Wheel Ackerman Steering: Driving and steering/turning mechanism that governs where the wheels point and how fast each of them will move.
Skills Necessary
This project has elements in mechanical assembly/fabrication, uses a host of electrical components, and has software that will run it all. In order to complete this project, you will need to have some experience in the following:
- Fabrication/Machining: Although most the parts are COTS there are a few modifications necessary to adapt them to the project. These modifications will be in the form of
- Metal cutting using
band saw/dremel - Drilling using drill press/hand drill
- Filing and sanding for part cleanup
- General Fabrication/Machining Safety
- Metal cutting using
- Electronics: This project uses components like motors, motor controllers, and batteries. It will be important to have experience with the following electrical processes.
- Soldering
- Electrical debugging
- Wiring
- Electrical Safety
- Software: The rover's brain is a Raspberry Pi. Included in this repository is all the software ready to run the rover, but some knowledge is required for getting everything up and ready on the Raspberry Pi:
- Basic Linux familiarity
- Basic Python familiarity
