In a studio at the Zhejiang University of Ocean University Undergraduate Entrepreneurship Park, Judi is seriously debugging the model battery balance charger. He wears a casual suit, wears a pair of rimless glasses, and is gentle and polite.

Can headspace create a new industry? The drone field may have such a new future. The student who was born in 1994 junior year, has been in business for three years, and Judi is aiming at the technical weaknesses of the drone battery life, accessories, etc., and tirelessly research and development, to make the team bigger and stronger, and to open up a road to wealth creation.

“Now the drone market is very mature, but the battery relay capability is poor. The aircraft is usually only 20 minutes in the air, need to return to the ground to charge or replace the battery.” In order to break this technical bottleneck, it took nearly 2 years R & D aircraft model battery balance charge to achieve aircraft charging in the air.

This upcoming model high-power smart balance charger is the required charging method for all lithium battery packs.

Judi introduced that charging in this way can achieve a balance accuracy of 0.001V, and more security protection, 6A maximum balance current, push-pull design, high charging efficiency, there are built-in 6-way charging circuit for each battery configuration dedicated charging Loops to achieve independent balanced charging systems that do not affect each other.

"Compared to big cities such as Shenzhen, it is very inconvenient to purchase equipment in Zhoushan. Sometimes, it can only be bought in bulk." Since the beginning of high school, Yan Di has had a keen interest in the model aircraft, but the development process is difficult.

“The material investment for the entire studio is almost 1.5 million yuan.” Ding Yanfeng told reporters that R&D investment is very large. They have been working with other companies to help some companies develop related accessories, so as to make up for the lack of funds.

"The hands-on operation is far more practical than the theory, and in order to develop new products, we must understand the most cutting-edge information, which is not learned in books. Although it took a long time and the middle also experienced numerous failures, but when the product When development is successful, that sense of pride and accomplishment is beyond words."

In just a few years, Judi’s team already has product systems such as drones, multi-axis heads, high-definition image transmission, and ground station control systems. Its products cover more than 10 areas, including police, firefighting, and agriculture. In the development of new areas.

In 2014, Judy's team assembled a drone and sold it to local companies for 150,000 yuan. Because the accessories are bought from the outside, the entire UAV's profit is only 20,000 yuan.

There are two kinds of drones to play, buy a machine or buy an assembly. Now that the drone market is very hot, the big manufacturers are more focused on doing the whole machine, and Judi believes that drone parts are the weak point of the market. He wants to strive to become the upstream supplier of the drone market.

"The original drone aerial photography, the photographs taken are not stable. We designed the three-axis head, can offset the vibration of the drone, stabilizing effect is much better than the ordinary two-axis head." Jody said, PTZ to use the whole Enclosed motor drive can effectively insulate sand, dust, iron scraps and other particulate matter, reduce the damage and damage, and prolong service life.

Sharpen the knife without cutting the firewood. In the context of the rapid development of the drone market, Judy's team has been focusing on R&D for the past few years. Now they are gradually shifting their focus to sales. Last year, Judy's team had a total income of 490,000 yuan on Taobao. Apart from Taobao, offline marketing also progressed smoothly. They also received order orders and private orders from some big companies with total sales of about 2 million yuan.

This year, they have already received orders of 2 million yuan from 2 companies and it is estimated that sales revenue will reach 6 million yuan. At present, Judy's team is making every effort to expand its market share, and is currently negotiating strategies with foreign big supermarkets.
