Adjusting Ballast on the Frame
To adjust the amount or position of ballast on the frame you need the following parts and tools:
7 x 200g Ballast weights (from original BlueROV2 Kit)
10 x 8-16 Thread, 5/8” Long, Thread-Forming Screws
1 x #2 Phillips head screwdriver
To get the longest battery life and the best driving experience, it is important to have the ROV close to balanced from
front to back in water and close to neutrally buoyant. The Newton Gripper adds a bit of weight to the ROV, so it will need
to be retrimmed based on your operating conditions. Trimming the ballast may involve a bit of trial and error.
Setup in QGroundControl
The following servo settings are available on ArduSub 3.5.3 and QGroundControl v3.2.4-BlueRobotics-Rev6 or newer. If
your software is out of date, please conduct a software update by following the instructions on the BlueROV2 Software
Setup (http://docs.bluerobotics.com/brov2/software-setup/) page.
The
Newton Gripper
can be controlled via the following button functions:
servo_X_max_momentary (open while pressed)
servo_X_min_momentary (close while pressed)
where
X
is the Aux Channel to which the gripper is connected. For example, a
Newton Gripper
plugged into Aux Channel
3 can be opened and closed with the
servo_3_max_momentary
and
servo_3_min_momentary
button functions,
respectively.
