Overview
The CHASING Grabber Arm 2 is a replaceable robotic arm for CHASING underwater drones, featuring a standard two-jaw clamp and a quick-swap interface for multiple tool heads (e.g., sediment sampler, circular claw, and other accessories shown). With a max opening of 170 mm, 7 kg grabbing force, and a 10° elevated mounting angle for a clearer camera view, it enables reliable clamping, dragging, and sampling tasks in inspection, science research, and environmental protection scenarios. The arm uses a sealed aluminum-alloy body that’s compact, lightweight, and easy to install.
