Adam Conway/William Roscoe’s RaspberryPi CNN-based car
This car was designed to be as simple. It uses a single camera and all the code is python. Current capabilities include: line/lane following, avoiding objects on sidewalks, and remote control via a mobile phone.
Full build instructions are here
- Hobby grade RC Car with non-integrated ESC (see below for suggestions).
- Raspberry Pi 3
- Raspberry Pi Camera
- Raspberry Pi Servo Hat (for connecting RPI to existing RC car)
- Usb battery + charger
The Donkey library was created to control this car. Its features include:
- Remote control car with a virtual joystick on your phone.
- Records image and telemetry data.
- Data pipeline for training autopilots using Keras Autopilot.

Hobby car platforms:
- Hobby King 1/16 mini rally car – This car is small but handles very well and can soak up some bumps.
- 1/10 Trooper Pro – A fast offroad car, but might be a bit loose for high speed road driving – CAD files available for a mounting plate and roll bar. Currently Adam Conway is using this car.
Tips for choosing a car:
- No need to get the “RTR” versions, these come with a transmitter(remote control). It is unlikely you will need or be able to use the remote that comes with these models. Choose the “ARR” version which typically comes with everything but a battery and TX/RX.
- Choose an ESC with a “UBEC” this will power your servo board connected to the raspberry pi, however will not power the raspberry pi.
- 4WD is nearly free in most cars now. While it will take a while for us to get cars fast enough to take advantage of this for performance, it does improve braking performance, which is important immediately.
