Camera Mount

The camera mount is designed with two mounting holes to be able to mount the camera stably at different angles. The food of the mount is screwed into the chassis with four screws.

Project Overview

Speed Sign Recognition

For this project, we are using ROS, motor speed feedback and DNN image recognition to dynamically change the driving speed of the car in response to speed limit signs.

What we did:

• started with getting the docker running
• calibrated the car for the speed control
• researched encoder theory and what we need for controlling the speed of the car
• reading output from the hall sensors
• setting a speed limit
• learning OpenCV
• printed out speed signs
• collected data for the image recognition
• recognizing the different speed signs
• integrating speed control and sign recognition into ROS
• testing
