SBrick Drive

What is it?

This project provides an abstract layer for SBrick Bluetooth controller for Lego in NodeJS. It focuses on controlling vehicle that can move in four directions: forward, backward, left and right.

How to play?

Three simple UIs are created to control a SBrick-equipped vehicle using this project.

1. Drive by Keyboard npm run drive-by-keyboard Drives a SBrick-equipped vehicle with arrow keys on keyboard of a computer.

2. Drive by Script npm run drive-by-script Drives a SBrick-equipped vehicle with instructions written in a text file, one instruction per line (my daughter loved practicing typing with this). A sample instruction file can be found at src/clients/script/instructions.txt.

3. Drive by REST npm run drive-by-rest Drives a SBrick-equipped vehicle with RESTful client. This task starts a Express server that provides the following RESTful API:

   • GET /drive/forward
   • GET /drive/backward
   • GET /drive/left
   • GET /drive/right
   • GET /resolveActionFromText/:command Use DialogFlow to convert free text/speech command into one of the directional command for SBrick.

   A simple web interface was created in src/web/index.html, which uses HTML5 speech recognition for the four directional commands (my daughter loved this too).
