Wow Laila! What a super idea! The pet robo-whale would certainly help clean up the plastic waste that is filling up our oceans. A clever idea to design the robot so that it can begin to break down and process the plastic waste inside its tummy, so that there is maximum space inside the collecting chamber for collected waste. I wonder what the plastic waste could be recycled into once deposited back on dry land? Perhaps another invention? Keep up the good work and send us some more ideas for unique inventions soon!
