Friday, February 1, 2019 Week 1 : In our first meeting, we developed a plan to make sure that the project will be finished in the followed 5 weeks, at this stage we were divided in to two groups, group 1 was responsible for the coding part, as they did some research over the most suitable coding program for programming the robotic arm to move using a remote control, meanwhile group 2 was searching for design of the robot arm with the most efficiency, furthermore, the team design a body car with 4 wheels and an arm attached to it, the wheel will provide motion to the arm which increases it's advantage. In the lab, we started with connecting the body car to a small voltmeter, battery holder, four wheels and motors, Arduino board so we can program the car and the arm, wifi deceive to command the car by a remote control, meanwhile the arm was formed by comping the left and right parts, three motors, holder, swing arm and a mechanical gripper which allows holding of a

Year 2 project, Robot Arm(week3)

Friday, February 15, 2019 Week 3: Before  attending week 3 lab session, we met the supervisor for some suggestions regarding the problem we are facing in the robot gripper, he gave us solutions to overcome the problem by either changing the gripper angle in coding or changing the construction of the gripper. In addition he suggested us to add a sensor on the edges of the car as when the car approaches to other obstacles, it sends feedback such as ps2 vibrations. In the lab session, we focused on solving the gripper problem. So we decided to change the gripper original angel and servo end angel which controls the gripper and it was tested several times. Finally the servo worked. Our next activity was to add a distance sensor HC-SR09 to the car to  send feedback to the ps2 controller in vibration form when the can approach any obstacle in its way. We tried to combine the two parts of the code, unfortunately id did not work, it seems like there is a conflict
