As the head of Robotics Lab in Woowa Bros, I lead and manage 70+ smart and passionate people (incl. 50+ engineers), who are building AI-powered autonomous delivery robots to innovate the delivery industry. Here are the 8 teams in my lab.■ Robotics hardware & firmware team■ Autonomous driving & robotics software team■ Perception & machine learning team■ System software team■ Cloud platform & service development team■ Test engineering team, specialized in testing autonomous outdoor robots■ Product management team■ Business development & operation teamSince 2022, we've hired ~40 outstanding people (37 engineers incl. 4 senior tech lead managers, PMs, and biz dev specialists). They have various backgrounds & experiences (They're from Google, NVIDIA, McKinsey & Company, Naver Labs, 42 dot, Kakao Mobility, Samsung Electronics, Coupang, Tmax, Skelter Labs, defense industry, and some top-tier schools in Korea, US, and China). We run a Sillicon-Valley-like hiring system, and these people passed very intensive tests & interviews.My philosophy and management style is well described in an interview article,https://brunch.co.kr/@123factory/40 (in Korean).Our product is named "Dilly". A brief introduction is at https://youtu.be/VYitQhmrB3c .Dilly has obtained operational safety certification from KIRIA, a government agency of Korea. This means each Dilly is granted the status of pedestrian. So Dillys can legally operate on any public sidewalks in Korea. A Korean news article: https://www.m-i.kr/news/articleView.html?idxno=1148480Dilly won some beauty contests, such as Red Dot Award, iF Design Award, Pin-up Design Award, and Good Design (GD) Award. https://www.mk.co.kr/en/economy/10987990We are also building server-side backends and tech infrasture for robot development and operation: https://2023.woowacon.com/?presentationId=628 (a video in Korean)We're full steam ahead to expand the service areas.https://youtu.be/ZeyV4PawVus
