Build a Robotic Arm for the Science Olympiad
Here is my code for the master slave. There are 2 bases (2 base servos) because each servo only rotates 180 degrees and some of the objects need a larger range of motion to be picked up during the competition.
For the current science olympiad competition I have constructed a robot arm by modifying the lynxmotion al5d. I am currently utilizing the master-slave system with an arduino uno as the microprocessor. However, I have been stumped on how to power the robot arm. I have been using 2 energizer brand alkaline lantern batteries (6v) in parallel for all of my servos and 1 9v alkaline energizer battery for the arduino. I was wondering how exactly you powered your arm (using what battery) and if you powered it all off the arduino or not. Should I individually power each servo or just collectively and should the servos be wired in parallel or series? Also for some reason, my arm often shakes, twitches, becomes out of control, or simply just shuts off and on repeatedly.
