Slee The Sloth
I'm running a 12 volt 3 amp power supply. Then I have a 12 volt to 6 volt DC step-down to power my EZ-B4 and servos. After the robot runs a little while sometimes the servos stop responding. But most often If I run a script to put the robots arm on its hip, sometimes it will work. Other times the arms will start to move and then the EZ-B4 will disconnect and then reboot.
I have also seen that after running a while the servos in the arms will start to run slow and not quite make it to there assigned spot. While the servos in the neck keep right on going like normal.
So I was thinking we did not have enough AMPS for all the servos. See I have 2 servos in each shoulder, one servo in the elbow, two servos in the wrist and one in the hand for a total of 6 servos in each arm. + 2 servos in the neck.
I started to look at the power supply. Maybe we do not have enough AMPS. So I grabbed one of R2D2's 12 volt 18 amp hour battery. R2 was not vary amused to see one of his battery's wandering off. While the servos ran a tad bit faster I soon ran into the same problems.
Any ideas? *confused*
