Servos not getting enough power?

Help & Support Robot Parts

I’m using a bot board II and a basic atom 28 microprocessor to power three servos, the HS-5645MG, HS-422, and HS-425BB. I have them plugged into pins 0,1, and 2 on the bot board II. I’m using a 6 volt battery pack to power the servos.

I am using a wired PS2 controller to control the servos. Everything has been working fine, but now I notice that sometimes the servos move slower or not as far as they are supposed, as if they are not getting enough power.

I used a voltmeter to check the voltage of the battery pack and it was 5.7 volts. Could this be why the servos are acting this way, or could it be another problem such as electrical interference.

I started noticing this problem when I started using all 3 servos. The problem did not occur when I was only using 2 servos.

What do you guys think could be going on?

What type of battery pack and batterys are you using?

I’m using an energizer 9 volt battery to power the logic, and a 6.0 Volt Ni-MH 1600mAh Battery Pack to power the 3 servos.

Buy one of the universal chargers from LM. Sounds like the battery voltage is the problem.

Attach the voltage meter across the batterys and watch the voltage when the servos move to see if there is a significant drop during the movement.
