Week Five Update

As Week 5 comes to a close the group has successfully completed line tracking with the robot. The group resolved issues with navigating the corners of the arena by replacing one of the light sensors with an additional color sensor. The color sensor is placed on the bottom, using the color blocks placed on each corner the robot will be able to navigate all four corners easily. The other color sensor will remain stationary and be used for passenger counting. As of now the passenger counter is still only able to count upwards. The group will continue to work on the issue of displaying the passenger count as it moves down.

 

Additionally, the group has developed a travel algorithm based on the location of which color corner the robot is on, and the availability of passengers. The robot will make decisions based on these two factors, which will allow it to navigate around the arena. This algorithm will be perfected by the end of Week 6. As for changes in robot construction the ultrasonic sensor has been moved slightly higher to make room for the addition of the color sensor. By the start of Week 6 the group hopes to start the integration of all of the individual aspects of the project that have been completed thus far.

Above is a video featuring the vehicle interrupting the Line Tracking code in order to perform a stop. The vehicle will stop once the ultrasonic sensor detects the presence of an obstacle.
