basura-pi

A prototype trash can sensor for the FSE 2019 Basura Trash System, installed on a Raspberry Pi Zero WH. For this prototype, an ultrasonic ranger is used as distance sensor.

A full documentation of the project can be found here.

This manual assumes that the Raspberry Pi already has a operating system installed (e.g. Raspbian) and connection to the internet.

Installation

Installing the sensor

For an installation manual on how to install the ultrasonic ranger sensor, see RpiAutonomousCar project.

Setting up a Virtual Environment

Set up a virtual environment in the project directory, e.g. in your home directory under ~/basura-pi

% cd basura-pi
% sudo apt install python3 python3-pip python3-tk
% sudo pip3 install virtualenv
% virtualenv venv -p python3
% source venv/bin/activate

Installing the requirements

(venv) % pip3 install -r requirements.txt

Installing the sensor driver

In order for the ultrasonic ranger sensor to work properly, a driver needs to be installed. You can use the driver from the RpiAutonomousCar project. For convenience purposes,the installation wheel for the Raspberry Pi is already stored under /wheels.

(venv) % pip3 install wheels/fse2017_robot-v0.1.0.tar.gz

Usage

Sensor Calibration

First, the sensor needs to be calibrated for the trash can and receive a UUID. Run calibration.py interactively and follow the instructions.

(venv) % python3 calibration.py

Starting the Logger Daemon

Now the logger daemon can be started.

(venv) % python3 main.py
