minibot-iface
Remote control interface for the MiniWorld robot. The robot uses a Raspberry Pi 3 B+, the camera module V2, an Adafruit motor hat and two differential drive motors.
Dependencies:
- Python 3
- NumPy
- pyzmq (https://pyzmq.readthedocs.io)
- picamera library (https://picamera.readthedocs.io)
- Adafruit motor hat library (https://github.com/adafruit/Adafruit-Motor-HAT-Python-Library)
- scipy (for image resizing)
Installing the dependencies:
# Picamera (may already be installed on raspbian distro)
sudo apt-get update
sudo apt-get install -y python3-pip python3-picamera python3-rpi.gpio python3-smbus i2c-tools libatlas-base-dev
pip3 install numpy zmq scipy==1.1.0
# Adafruit motor controller library
git clone https://github.com/adafruit/Adafruit-Motor-HAT-Python-Library.git
cd Adafruit-Motor-HAT-Python-Library
pip3 install --trusted-host pypi.python.org --user -e .
To enable I2C ports, you should uncomment the necessary line in /boot/config.txt, and add a line with i2c-dev to /etc/modules.
Troubleshooting
Note that some Python packages can take forever to build and install with pip. It's worth consulting the list of available precompiled wheels on piwheels, and specifying to install a package version that you know has a precompiled wheel.
