MATE ROV 2017

Over view of the Project

I Joined the HKUST Robotics Team - ROV Subteam (EPOXSEA) in my first year to work as CTO and Mechanical Engineer. I was in charge of designing most of the robot's manipulators such as Main Gripper, Value Turner, Marker Buoy, Agar Sampler, and Bluetooth Activation Module.

We won All-Round Champion of Explorer Class in the MATE ROV 2017 International Competition Grand Final after winning Regional Champion in Hong Kong.

My Manipulator Designs 

Main Gripper

The Main gripper was designed to be adaptive to different shapes by increasing number of contact points. Soft rubber tubing was used as fingers that help the gripper to firmly grab the desired objects.

Finger gripper

The finger gripper was designed to be a back up for the main gripper, it can also adapt to different object shapes and acquire a firm grip. However this design never got manufactured as there was worries regarding the reliability issues brought with the complex structural design.

Bluetooth Activation Module

The Bluetooth Activation Module combines the Activation Module, which uses light signal to active the Bluetooth communication, and the Bluetooth Module to carry the communication, it is compact and easy to use for the robot pilot.

Agar Sampler

The Agar Sampler was designed as a one-way flap door mechanism. Over repeated penetration into the agar sample, it is able to acquire a good amount of samples to bring back to shore.

Marker Buoy

The Marker Buoy was used to mark underwater containers on the water surface. Magnetically attached to the robot, it can be attached to the underwater container, after which it will float to the surface dragging a internally winded string.

Value Turner

The Value Turner was designed to perform the task to turn a value handle underwater, it took an old gearbox, for which adapters and housings were made to adapt to a water proof motor.

The final version also feathers an adaptive claw with which the pilot can more easily turn the value handles of different shapes and sizes.
