Overview
The basic concept of how the Elcano Project vehicle works.
System Architecture
How processors connect to sensors, each other, actuators, and other hardware. Includes processor-to-processor communication protocol.
Communication (CAN Bus)
How processors exchange data on the vehicle and a description of data packet contents.
Power System
How different modules connect to the batteries or power subsystem hardware.
Low Level
How the Low-Level system (aka Drive-By_Wire) uses inputs to control actuators to steer, move, and stop the vehicle.
High Level
How the High Level (aka Sensor Hub) system uses stored maps and inputs from navigational sensors to formulate movement instructions sent to Low Level.
Using a stored map of the area of operation, nodes will be created around the map as appropriate. The vehicle program will then implement Dijkstra's Algorithm to get from the starting node to the desired node. Should the vehicle encounter an impassable obstacle, it will revert to its most recent node visited and reimplement Dijkstra's Algorithm. However, this time, the pathing where the obstacle lies will be ignored to use a different path.
If an obstacle can be traversed around, then the vehicle will sense which side (left or right) of the path is being occupied by the obstacle. The vehicle will then veer to the left or right accordingly. There will be sensors to ensure that the vehicle won't go over the path edge, which could be dangerous. In this scenario, the vehicle will reverse and consider the obstacle impassable.
RemoteControl
Human control of trike movements through Low Level using hardware connected to Low Level by a radio communication link (drive-by radio). Includes onboard controls (drive by wire).
Simulator
Using the Open-source CARLA platform with a go-between board allows simulation.
SensorsPage
SteeringSensor
The front wheel angle detector.
Sonar
How the sonar subsystem connected to High-Level works.
Lidar
How the lidar subsystem connected to High-Level works.
The LiDAR sensor is able to detect the distance and angle of any object in its view. This data can be used by the high-level software to determine where an obstacle is located for the vehicle to avoid.
Camera
How the camera and vision subsystem connected to High-Level works.
ActuatorPage
Board Diagrams
Images of Elcano Project's printed circuit boards for reference. PCB source files and schematics are maintained and stored at [1].
Software development procedures
Software repositories
What's in each of our GitHub repositories.
Luke Kustra's repo: https://github.com/luke-kustra/JetHawk-LKustra.git
Luke's contribution was experimenting with the LiDAR sensor. He was able to get the LiDAR to deactivate and display information about its surroundings, including the number of objects and their distance from the LiDAR sensor. Of course, the sensor should never deactivate when in real use; however, this deactivation is proof that the LiDAR is ready to be utilized in a larger system such as a vehicle.
Henry Haight's repo: https://github.com/Autonomous-ATV-Capstone-Team-Sequence/-LIDAR
Arduino software
Getting started; references; development tools. Dealing with libraries and different parameters for each vehicle.
Using Git and GitHub
Practices for maintaining code and source files on Elcano Project's GitHub repositories.
Files
These are media files (pictures, videos, etc.) that are part of the project but are not maintained under version control.
