Hi everyone,
For my project I am designing a robotic arm. I intend to fix this arm on the top of a pioneer 3dx robot later on.
Following are the details of the motor and motor shield I will be using for my project :
Motors details:
-
http://www.andymark.com/product-p/am-2971.htm (12v 22 amp stall current 16 ft-lbs torque)
-
(2 of these) Pololu - 131:1 Metal Gearmotor 37Dx57L mm 12V with 64 CPR Encoder (No End Cap) (12v 5 amp stall current 18 Kg.cm torque)
Motor shield deatils: (I have the following motor shield as it is compatible with arduino)
• Low-cost robust H-bridge ''shield'' for Arduino
• Provides the ability to control up to 30A of current at up to 28V
• Supply voltage: 5V to 28V (24V max battery rating)
• Continuous output current: 13A
I am considering to use a battery to power the system.
I thought of going for 12v 22 Ah battery but its too heavy to be carried along the mobile base.
Then I thought of using pioneer 3 dx robot's battery to power my manipulator. Rating are 12v 7.5 Ah.
But again I am confused whether to go for it or not since one of the motor will be drawing currents at around 15 amps of current . should I go for it ?? will it work?
