Our lateral (steering) controller is currently just a heuristic, and might not adapt well to different driving environments.
Our longitudinal (throttle and brake) controller does not exist yet, except for the trivial "bang bang" controller for SVL.
Apply adaptive PID control techniques to control both the steering, throttle, and brake.
Two nodes exist. One publishes steering commands on a /control/steering
topic, and the other publishes on both a /control/throttle
and /control/brake
topic.
Right now, Navigator controls steering in two stages. The first generates a desired steering angle, and another (PID) controller converts this into effort. These should be merged so that the steering effort is generated directly.
Both controllers can (theoretically) adapt to different driving conditions, such as fairly sharp turns, wet roads, etc.
Both controllers are tested and validated in tandem using the SVL simulator.
When executing sudo in fresh ADE installation, the terminal hangs for a few seconds and then fails:
docker@vde:~$ sudo true
sudo: unable to resolve host vde: Temporary failure in name resolution
Reverting to 7214008 fixes it... Must be something wonky with the host configuration in Docker.
