The LitterBug is a trash pick up rover built off the Donkeycar platform. It's goal is to help pick up trash in beaches, parks, etc as well as provide a fun and relevant context for which to learn about self-driving vehicles, AI, and robotics.
- LitterBug Build instructions and Software documentation
- LitterBug Write-up (for more details on experiment)
- Create a version of a real life WALL-E!
- Experiment with autopilots, mapping, computer vision, and neural networks.
- Train your rover to pick up trash anywhere (..and have fun while saving the planet)
- Log sensor data. (images, user inputs, sensor readings)
After building a Litterbug, press the select button on the ps3 controller and get rolling.
You can make the LitterBug interact with the environment in new ways by adding a new physical part. For example, this project added a scoop part using an extra servo. Since the LitterBug is built off the Donkeycar platform, you can use their structure to create new parts.
#Define a vehicle to take and record pictures 10 times per second.
from donkeycar import Vehicle
from donkeycar.parts.camera import PiCamera
from donkeycar.parts.datastore import Tub
V = Vehicle()
#add a camera part
cam = PiCamera()
V.add(cam, outputs=['image'], threaded=True)
#add tub part to record images
tub = Tub(path='~/mycar/get_started',
inputs=['image'],
types=['image_array'])
V.add(tub, inputs=['image'])
#start the drive loop at 10 Hz
V.start(rate_hz=10)You can also control your new part by mapping an unused button on your PS3 controller. Modifying the donkeycar/parts/controller.py file:
#AVAILABLE BUTTONS = ['tr', 'tl2', 'tr2', 'mode', 'thumbl', 'thumbr']
#AVAILABLE AXES = ['y', 'z', 'rx']
#In the update() method of the JoystickController class add:
if button == '<AVAILABLE BUTTON HERE>' and button_state == 1:
#do something!See LitterBug write-up, donkeycar resources, or join the Donkeycar Slack channel to learn more and share your build.
