Adding gyro sensor
Because the distance sensor coupled with the color sensor does not give us good accuracy approaching the enemy. Today we decided to install the degree sensor as well.

Adding the crane
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 .
Building the environment
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.
Adding sensors
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 first step, we start reassembling the robot.
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.
