Newton Gripper Assembly
Newton Gripper Mount

- Initial release.
**Keep fingers and other body parts away from the gripper when operating!** It’s strong and has the potential to do some damage. Notify other crew members to do the same.
If the gripper is continuously cycled rapidly for over a minute, the motor may overheat and melt the rotor frame. Please do not cycle open and close for over a minute and allow for a proper cool-down between quick cycles.
1. Connect the signal wire to a signal source such as the Pixhawk on the BlueROV2 or a 3.3v microcontroller.
Arduino microcontrollers have a 5V DC PWM Output. This is listed as “operating voltage” on the specification table. If using the Newton Subsea Gripper with an Arduino, you will need a Logic Level Converter.
- Yellow: PWM (3.3 volts only)
2. Connect the power wires to a power source.
- Red: +9-18 volts
- Black: Ground
