GRIT: A Graphical Route Inspection Tool for the Perseverance Rover.

Mars Rover Planners are studying the potential for AutoNav Monte Carlo simulations to help them assess the risks of extended automatic navigation over challenging topography. GRIT summarizes thousands of simulated AutoNav runs for Rover Planners to investigate and understand potential failure cases.

Setting Up the Local Environment

Installing Node.js with n

We will use the Node version manager n to install the required node version:

1. On Linux and Mac OS, install the n package manager:

   curl -L https://bit.ly/n-install | bash

2. Install and use the specific Node.js version required (18.17.1) by running:

   n 18.17.1

3. Verify that the correct version of Node.js is installed:

   node --version

   The output should be v18.17.1.

Installing Dependencies

To install project dependencies, run the following commands in the root directory:

npm install
npm install --save node-releases

These steps will install dependencies locally into a node_modules directory.

Running the Application

The frontend code is written using the Svelte framework. Run the following command in the root directory to compile the Svelte code into JavaScript code:

npm run build

To start the application, run the following command:

npm run dev

and finally, navigate to the following URL:

http://localhost:5173/?data=aug20-1

This application was developed as part of the Caltech/JPL/ArtCenter Data to Discovery (D2D) Summer Data Visualization Program. In the 10-week D2D program, visualization faculty at Caltech, JPL and Art Center College of Design work with talented design and computer science student interns in collaboration with Caltech and JPL research groups. Together, teams develop custom-built interactive data visualization tools for science and engineering research projects using the state-of-the-art techniques.
