This is the last week of the semester. The servo motors on the arm had to be readjusted so the arm is actually a right arm and can move like one. Tests were done to check the proper angles of each servo to make the movements lifelike. These notes can be found below in the scanned notebook. Also during this week, basic smooth gestures using the arm were made (allowing the wrist and hand to wave). When applying more complex gestures issues arose. The two wrist servos and the one elbow servo wouldn’t run together. Therefore, the arm couldn’t lift at the elbow and wave. I believe it is due to the different duty cycles being received by the servos. Tests can be found in the notebook. Lastly, data was given to Karissa and I based on the brain signals. The results can be found in the scanned notebook below. It shows that the electrode placements on channels 3 and 5 produce the same signal. One final update will be made for the progress at the end of the semester and the next steps.
