The motivation of the project is that humanity had explored until now only 5 percents of them. After subscribing to the competition, the participants will have one year to develop the robots for the first round of competition which is expected to last three years, with two rounds of judging. The first step will be have operating robots at an ocean depth of 2,000 meters, or about 1.2 miles. In round 2, up to 10 finalists will put their robots to the test at 4,000 meters, at around 400 atmospheres of pressure , over 5,800 pounds per square inch. There’s also a bonus prize of $1 million, sponsored by the National Oceanographic and Atmospheric Administration, that will reward the first team to develop new biological and chemical sensor technology.
