This is a python based interface to control RC hobby car, typically those under the label "RTR" or Ready To Run, and ultimately mhake them autonomous with a webcam.
The raspberry pi will send pulses on its GPIO pins, allowing different speeds and anglesd
Todos:
- Main car. Equivalent to main robot loader/builder/truck/renovator IRL
- (done) Show voltage and temperature
- Add variable speed, with cursor command on page
- Add httpauth, dynamicdns with access from outside network
- Add removable actuator to front: loader, wallet transport, welding, 3-degree robot arm, sensor (soil humidity)
- Use USB controller (Playstation, XBox) to drive (optional)
- Camera sensor:
- Add a combination of LIDAR fixed cam and a m4/3 Z-CAM E1 camera with pan/tilt as secondary large sensor camera. Use RC battery to power. Use FPV hmdi converter to feed video
- Add face recognition to main camera. Stop robot if recognize. Open door for delivery if authorized.
- Add HDR+ to main camera http://timothybrooks.com/tech/hdr-plus/
- Indoor positioning system with cameras placed on ceiling, car with "QR Code". Equivalent to a drone IRL
- Add pathing A to B
- Protected Garage with wireless charging. Equivalent to a base IRL
- Python 3.4

Optional: you can choose a raspberry hostname of your preference by editing file:
$ sudo vi /etc/hostname $ reboot
Open a tab
$ cd /usr/src/mjpg-streamer/mjpg-streamer-experimental
$ ./mjpg_streamer -o "output_http.so -w ./www" -i "input_raspicam.so -x 640 -y 480 -fps 20 -ex night"
Open a third tab to get Raspberry Pi send user commands to SBrick Pi through Bluetooth
$ sudo python3 drive_api.py -s 50
Open a last tab to record stream and session commands
$ sudo python3 record.py
Happy driving
