Maker Project Builds Self-Driving Toy Car
A maker project documents a do-it-yourself autonomous toy car that pairs a small neural network with a PID controller to steer around an obstacle, per its Hackster.io listing and a Hackaday.io project page. The build runs on a SparkFun RedBoard Artemis ATP microcontroller, programmed with the Arduino IDE and supported by Python tooling. The project page is organized into hardware, machine-learning, PID-controller, printing-and-assembly, test, and conclusion sections, includes a wiring schematic, and links to GitHub repositories for replication. It is a hands-on embedded-ML reference build rather than a commercial or research release; the documented project dates to 2020 and resurfaced through a recent Hackster listing.
What happened
Per the Hackster.io project page and a Hackaday.io project mirror, an individual contributor published a do-it-yourself autonomous car that uses machine learning plus a PID controller to steer around an obstacle. The project lists hardware, machine learning, PID tuning, printing and assembly, test procedures, and links to repositories on GitHub, per Hackaday.io. The build centers on the SparkFun RedBoard Artemis ATP microcontroller and uses the Arduino IDE and Python as development tools, per the Hackaday.io project page.
Technical details
The project documentation presents separate sections for MACHINE LEARNING and PID CONTROLLER, and includes a schematic and code repositories, per Hackaday.io. The SparkFun RedBoard Artemis ATP is described on the project page with its Arduino Uno R3 footprint and onboard resources including 1M flash / 384k RAM, a 48MHz core with 96MHz turbo capability, multiple GPIO and peripheral buses, and an on-board BLE radio, per Hackaday.io. The project includes a printing and assembly section and notes about 3D printing, and the writeup includes step-by-step assembly and testing notes.
Editorial analysis
Industry context: Projects like this are representative of hands-on embedded-ML learning, combining a small microcontroller capable of local inference with classical control such as PID for closed-loop steering. For practitioners, these builds illustrate tradeoffs between model complexity, runtime constraints on microcontrollers, and the need for deterministic control loops for stable navigation.
For practitioners
What to watch: Observers and hobbyists will find value in the linked GitHub repositories and test footage for evaluating real-time performance, on-device memory and CPU usage, and the integration approach between the learned policy and PID control. Reproducibility signals to watch for are clear model artifacts, training data or pipelines, and measured latency or failure cases, if reported by the author.
Key Points
- 1The build combines on-device machine learning with a classical PID control loop, a common pattern for teaching real-time perception-to-action on constrained hardware.
- 2It runs on a SparkFun RedBoard Artemis ATP, showing how a low-power microcontroller can host simple inference alongside a deterministic control loop.
- 3Published schematics, 3D-print files, and GitHub code make the project reproducible, which is its main value for embedded-ML learners.
Scoring Rationale
A reproducible hobbyist build combining embedded machine learning with PID control - genuinely on-topic for embedded-ML learners but niche, and not a research or commercial release. Scored at the low-visibility floor to keep an on-topic instructional project discoverable without overstating its industry impact.
