DAY 1
During the first day of work, Keegan has been working on starting to program the software that will make our robot run. He has downloaded the EV3, and he has been working on connecting the robot to the computer. Brandon and me have instead been working on giving shape to our robot, so that, once the program is uploaded, it will be able to move, orient itself on the board and follow directions. We tried to make the robot so that it was as light as possible, while also being able to move freely and not fall apart. We also wanted to make sure that the robot’s visual sensor was placed in a way such that it could work at its best.
DAY 2
Today in class Keegan was downloading a test program to check if the system and motors were functioning properly. He also took a deeper look into EV3 to start to get some experience with it. Luca and Brandon attached the other color sensor to the back of the robot. All three group members then worked to come up with an algorithm that can make it pass the challenge. They looked up possibilities of the layout, and decided that they needed to create an algorithm that can recognize if it senses a drift or stench from one area, moves, and then recognizes that same drift or stench, then it will identify the space where it is coming from.
DAY 3
Today in class we continued to refine our algorithm. We tested the algorithm and our own understanding of the problem against the professors. This meant solving a number of Wumpus World problems, trying to understand what the robot will have to do when it is going to solve the puzzle. This led us to conclusion about some of the questions the robot will have to ask itself, and be able to answer, too. Also, we were able to make a logical algorithm based on how we would solve the puzzle.
DAY 4
Today we tried to get the robot to move. We made some coding for simple movements to find out motor configuration and rotational directions. The code that we made was not accepted by the robot. The demo code that we used was accepted, but when we took the demo code, and placed it under a different name, the robot did not move. We seem to be having a problem with the root accepting code that we created, even if the code was accepted by the robot before.
DAYÂ 5
Today the Wumpus Master Sam helped our programmer with design and programming. He cleared up some of the issues we were facing with the program downloading to the robot. He also showed us how to test a program while the robot is still connected to the computer so as to test programs quickly. We were able to clear up some issues with the readings the color sensor because of the distance the sensor was from the ground. We ended up switching from having one color sensor at the back of the robot to having both at the front. He then helped Keegan with knowing specific functions for using the color sensor, different ways of making the robot move, and a few others. He all around helped clear up a lot of the issues our group was facing.
DAY 6
Today we were able to successfully program the robot to move in a figure eight and return to the starting square of the puzzle board. We were able to successfully use the color sensors to make the robot orient itself based on when it passes over the line. The only problem sightly troubling us is that some of the distances that the robot goes are a little too much. The robot does not exactly end up in the middle of the square always and can be a little close to the edge. Most of the time the robot can fix itself though. Today we also worked on updating the website and making sure it looked nice and up to shape. The logic for solving the puzzle is still being worked on, but should be completed soon.
