+# RC Car
+Scripts for controlling the RC Car. A system overview is shown in figure 1. All algorithms are executed on a workstation that transmits the steer and speed commands over radio to the car. The car sends a video stream of the camera over wireless HDMI to the workstation. Further, a browser-based user interface is available.

+*Figure 1: System Overview*
+
+The control_server can be started with:
+
+```
+python control_server.py --model-dir ../trained_models/rl/ppo/ppo_foyer_obs8_exp_4  --cam /dev/video0 --model-filename best_model 
+```
+The video stream of the camera should be available on the workstation.
+The configuration of the transmitter, which should be connected to the workstation, is defined in [config.yml](./config.yml).
+
+For RL models with the Yolo object detector, the path to the trained Yolo model can be specified with
+```
+--yolo ../trained_models/yolo/TinyYoloModified_cardata.pth
+```
+
+The port of the user interface can be specified with `--port 8888` for example.
+
+The user interface can be accessed over HTTP:
+
+```
+http://ip_workstation:8888
+
+```
