Happy Edu

Fig.1 Happy Edu and its modular components

Since 2015, our robots have featured a friendly, approachable design to encourage acceptance among children, women, and the elderly in home environments. Based on this philosophy, we developed Happy Edu (Fig.1) in 2023—a small, lightweight, and affordable open-hardware robot aimed at lowering entry barriers for new RoboCup@Home teams.　For RoboCup 2026, we are implementing the following enhancements:

• Replacement of the 2D LiDAR with a 3D LiDAR

• Extension of the robot arm to 6 DoF with improved payload performance
