Food Delivery Robot Year 2 Project

Week 5 Prior to the Bench Inspection: After meeting as a group, we felt that the robot could still be improved, we decided to adjust the code slightly, with the inclusion of a code for the Ultrasonic Distance Sensor. The Robot car now moves when the front sensor is touched. This is so that the hotel guest can notify the completion of their delivery, and prompt the robot to continue along the track.  This was tested: Week 5 Bench Inspection:

Overall Poster: Introduction: Schematic: Where these are the schematic diagrams, with the robot one being in the Introduction Entry and the track viewed across the Week entries to show the progress. Software: Where this is the summary of the alternative methods mentioned in the blog entry for Week 4. Hardware: Where the images can all be viewed in higher quality in the Introduction Entry of the blog. Method: Where this is simply a summary of the tasks we completed in order to finish the robot.  The code flow chart can be seen below: Results:   Where this is a general overview of the functionality of the robot and the main components that allow for the robot to work. Conclusion: This section summarises on if we met the aims we originally created and given more time, what would improve the functionality of the robot.

  Week 4 Pre-Lab: During the weekly meeting, there was an issue with the motor and wheel mechanism of the car, after meeting with the supervisor, we discovered that the screw that connects the gear for the track-wheel to the motor had moved out of place, therefore causing the whole system to not function correctly. As the solution was to simply return the screw to its original position, the problem was overcame. The plan for the Week 4 Lab was also discussed, as with limited time and the track design not being finalised, we had to decide on the best solution if the track with black tape doesn’t work; with alternatives including using paper with the track printed on. We confirmed that the original track design was too thick as the tape caused an overlap with the Infra-Red Sensors and caused unwanted turning as well as stops that we didn’t anticipate.   Week 4 Lab: As the motor issue was fixed in preparation for the final lab session, we swiftly progressed onto testing, re-design
