This is done as a final project for CMP202 (at Chatham University) - introduction to programming (with Python).
The program allows Cozmo Robot to autonomously navigate through an "unknown" maze and find a way out using depth-first search algorithm.
- Other contributor: Jordan Schultz-McArdle
- Three methods are written by Dr. Rosenthal (guidance faculty for this project) - matneighbors(), getnavidirection() and navigate_path().
- Due to limited time of the project and limited knowledge of Cozmo's vision (Cozmo does not have object sensor, only camera), we did not use Cozmo's vision to detect the maze's wall. Instead, we input the location of walls of the "unknown" maze in walls() method.
- This program runs with the previous version of the SDK (before Cozmo SDK update in December 2017). The update may have changed the turn and drive function which will affect this program, may need to be changed accordingly to the new update.
In order to run the program, user will need a Cozmo robot, a compatible mobile devices, Cozmo free app, a computer that has Cozmo SDK.
Instructions to install Cozmo SDK and how to run SDK files can be found in this link
after installing SDK, to run the program in this folder, simply type into terminal
./FinalMaze.py
The program runs with default starting location of A1 and South as facing direction. To change these values, change these values in line 176
If you try to run the file and got the message "Permission denied".
Follow the following steps to get the file running
- Download Cozmo sdk example file
- Duplicate one of the example file.
- Copy and paste this program into the duplicated example file
- Run the duplicated example file with the content of this program
In the video we have to realign Cozmo once in a while because the friction between his tread and the mat used prevent him from turning exactly 90 degrees.
