We report about a forklift hailing application we built using MicroPython and the ESP32-based prototyping hardware M5Stack. In a production facility, machine operators can hail a forklift using an ESP32 device running MicroPython. The device sends a request to a forklift dispatcher software, written in Python. The request is queued and subsequently, the next available forklift is notified and sent to the machine. Each forklift is also fitted with an ESP32 device. In this project, the prototyping hardware M5Stack was used. It features an ESP32 micro controller with Bluetooth, WIFI, GPIO, three buttons, and a display.
MicroPython and prototyping hardware can be used to scale from an idea on the developers desk to a working system in a rough Industry 4.0 production environment. The talk will recap our journey with MicroPython, the lessons learned, and the pitfalls to avoid. Furthermore, the tooling setup will be introduced, including our M5Stack GUI-simulator to mock the M5Stack display.
The central dispatch server is built using Python and deployed in a Docker container. Messages are exchanged using MQTT, a popular IoT message protocol. The talk will conclude with a live demonstration of the forklift hailing system. Attendees should be comfortable with the Python syntax but are not expected to have any MicroPython, MQTT, Docker or domain knowledge.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
