MBot

This is the guide for mbot and connecting it to remo.tv

Please note, I am not responsible for any technical errors during this process, and may not be able to provide support. You can still contact me on the remo.tv discord at: @sticks#0001

Hardware

What you need:

1. A camera
2. The mbot kit and the mcore bord
3. Speaker
4. raspberry pi 3+ or 4
5. internet
6. Battery pack

Now what you want to do, is follow the instructions to put together the bot, linked here.

After that's done, find a place for the pi, camera, speaker, mbot core board, and a battery pack

A wiring diagram is below for battery:

• Battery -> Bot: Connected to Cam
• Battery -> Bot: Connected to Speaker
• Battery -> Bot: Connected to mbot board (not USB, 4 AA bats)

The wiring diagram is below for connections to pi and mcore board:

• pi -> Cam: Connected to Cam over USB
• pi -> Speaker: Connected to Speaker over AUX
• pi -> mcore board: Connected to mcore over USB serial

Controller Configuration

The robot type must be serial_board.

The code for the Arduino

The following code must be flashed to the board with the mbot software.

// RemoTV Controller for mbot
// Code used: Dan's handler,mblock init things
// compiled and published by sticks

}

//delay code (some wired thing)
//void _delay(float seconds) {
//  long endTime = millis() + seconds * 1000;

// this is motor moves 1,f 2,b 3,r 4,l
