I am currently working an a personal hexapod robot project. I am building it using 18 MG996R 4.8 to 7.2 V servo motors. I would like to use a Raspberry Pi 3 B+ to control it. I purchased a 7.4 V 8000 mAh Li-Po battery to power the motors. I am currently having trouble finding a servo motor controller that supports more than 16 servo motors that also would support a 7.4 V power supply. I am new to this and find myself with a lot more questions than answers.
- Are there any large servo controllers that can support more than 16 servos that would also work with a Raspberry Pi?
- Is the battery I bought too big at 7.4 V?
- Should I be using a voltage regulator to tone it down and how would that effect my current output?
- Is it possible to stack two 16 channel servo controllers?
