Defender Bot DevLogs

 Modifications to the construction of our robot continued with the addition of a crane. The crane is attached above, in the shape of a propeller, at an angle that allows the enemies to be shot down. At both ends of the crane we have a weight in the shape of wings, which facilitates the speed and accuracy of the attack .

       This stage consisted of building the robot environment. For this we used a large piece of cardboard, which was glued with black tape. We initially planned not to use the robot's guide lines so that the robot would only be guided by the motion sensor, but due to sensor limitations, we decided to use these lines to increase the robot's angle of accuracy.       So the card has 6 lines, at the end of each is the enemy. When the robot starts its actions he is in the middle of the intersection of these lines . As enemies we used empty plastic bottles that have different colors on them, green, red, yellow. Depending on the color, the type of enemy also differs.

 The next thing that was implemented in our robot was the addition of motion and color sensors. We insisted that the sensors be placed together, one below the other for better coordination. Also we thought about the appearancepart, the sensors look good, so that this part of the robot has a pleasant appearance.

  The purpose of this step is to realize the concept of the robot, how it should look and function according to the requirements it has to meet.      W e started by designing the base, the platform on which the robot will have its equipment attached.We kept the platform from our previous robot, making a set of changes .Then we built and attached the set of wheels and 2 motors through which it will move.      T he Lego Ev3 Mindstorm computer we put at the center of the construction, in order to have an ideal balance and to have access to its ports and buttons.

 At first we assembled a robot whose set of actions was as follows: it observed the enemy with the help of the motion sensor, approached it so that it could see its color, and with the help of the color sensor to identify the type of enemy after which he lowered the crane with the help of the thread and at the same time with a rotation he made the blow. But considering that the sensors were not positioned very well and the robot's movements could not be perfectly defined by us, we decided to redo its construction.

  Join us in our journey. A journey in which we accomplish to create a defender bot whose purpose is to carry out attacks and defenses. Our team:  Cojocaru Augustin-Stelian - 2123621  Gorodetchi Pavel - 2123121  Ilies Daniel - 2123721 Stoica Eugeniu - 2122921
