The hopeful future of humanoid robots under Hanyang University students

Hanyang ERICA Robot Engineering for Human Society (HERoEHS) Team is made up of Hanyang University students that has a record of competing in renowned robotic contests. The “Ski Robot Challenge” was held as an opening event of the Pyeongchang 2018 Winter Olympics, in which the team built a humanoid robot that would later be the foundation event of creating a soccer robot for RoboCup Korea. RoboCup 2018, held in Montreal, Canada, was another chance that allowed the team to make further improvements. RoboCup Korea Open 2019, held from February 14th to 16th, had around 800 participants formed into 290 teams, being the largest in size so far.
Consisting of five members, Park Jae-hoon (Division of Computer Science, 4th year), Min In-joon (Department of Interdisciplinary Engineering Systems, Master’s program), Kim Hyun-suk (Department of Integrative Engineering, 2nd year), Choi Jung-hun (Department of Mechatronics Engineering, Master’s program) and Yoo Dong-ha (Department of Interdisciplinary Engineering Systems, Master’s program), the team shared their story of how they won the adult size league of RoboCup Korea Open 2019.
From the past experience of Ski Robot Challenge, the team knew that the ski robot, unlike the soccer robot, needed not the ability to walk but driving force. Weight reduction was the main project the team faced in order to make it walk, along with developing a walking specialized algorithm to prevent the robot from leaning toward one particular side while walking. HERoEHS has been supplementing what the team missed in RoboCup 2018 Montreal ever since it ended last June 22nd, and they spent a month focusing entirely on preparing for RoboCup Korea. The team had the help of Professor Han Jae-kwon (Department of Interdisciplinary Engineering Systems), who won the championship at the World RoboCup for three consecutive years and is a renowned expert in the field of robotics.
The RoboCup had three leagues, which differ in the size and weight regulations of the robots: kid size, teen size, and adult size. There are more participants in the smaller size robot leagues, as they are less challenging in comparition to the bigger ones. The participants run tests on the actual playing field, and collect data from their robots by observing whether or not the robots are aware of the goal posts, the ball, and opponent robots. Gathering the necessary data was another reason the team joined the RoboCup contest this year.
The HERoEHS is planning on entering RoboCup 2019 Sydney in June. The rules will have slight changes, with the adult size league consisting of robots competing two-on-two, instead of one-on-one. They will focus on lightening the weight and addressing any changes in the quality of the material, and change the motor into one with more torque. “Although participation in a world RoboCup contest itself is meaningful, our goal is to be in the top ranks this time.”
