Product Description

The Newton Subsea Gripper is a single function manipulator for the BlueROV2 and other subsea vehicles. It’s the result of several years of effort starting with a senior project in 2016 and evolving into the current design over several iterations. Each element was carefully designed and combined to create an awesome ROV tool.

The gripper has jaws that open to grab objects up to 2.44″ or 6.2cm in diameter. The plastic jaws are mounted with custom aluminum screws to create a corrosion resistant mechanism that doesn’t need any lubrication. The jaws are driven by a linear actuator that uses a geared brushed motor and lead screw. The main body is air-filled and sealed with O-rings. We’ve spent a lot of time testing it at pressure and it’s rated to 300m depth with plenty of safety factor.

The motor inside is controlled by a purpose-built brushed motor controller that accepts a standard servo-style PWM signal so that the gripper can be controlled just like our thrusters and lights. Power can be provided by the same battery that drives the thrusters as the gripper is compatible with 9-18v input and draws up to 6A current. It automatically detects motor stall conditions and stops the motor so that the gripper will always stop at the right moment. Check out the launch video to see that in action!

The gripper comes with everything needed to use it on the BlueROV2, including an anodized aluminum mount that uses a thumbscrew for quick retraction and rotation in the field. The mount attaches with two included M5 screws.

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.
The motor may overheat and melt the rotor frame if the gripper is continuously cycled rapidly for over a minute. Please do not cycle open and close for over a minute and allow for a proper cool-down between quick cycles.

Quick Start

The Newton Gripper is controlled using a servo style PWM signal. Follow these instructions to control the Gripper using PWM directly. If you are installing the Gripper on a BlueROV2, visit the Newton Gripper Installation guide.

1. Connect the yellow signal wire to a 3.3V PWM signal source such as an autopilot board or microcontroller.

Many microcontrollers, like the Arduino Uno, have 5V PWM outputs. This is listed as the “operating voltage” in their tech specs. If you are using a microcontroller that operates at 5V logic, you will need a Logic Level Converter to bring the signal voltage down to 3.3V.

2. Connect the red and black power wires to a 9–18V power source.

  • Red wire: +9–18 volts
  • Black wire: ground

3. Provide a PWM signal to operate:

  • 1500 microseconds (μs) for neutral (no movement)
  • Greater than 1530 μs to 1900 μs to open
  • Less than 1470 μs to 1100 μs to close
