Rainbow Robotics RB-Y1
Rainbow Robotics RB-Y1 is a dual-arm mobile manipulator on a 131 kg wheeled base.
The RB-Y1 is South Korea's first dual-arm mobile manipulator, unveiled in April 2024. The humanoid upper body with two seven-axis arms sits on a fast wheeled base. According to reports it is 1.4 m tall, weighs 131 kg and travels up to 2.5 m/s. Each arm has a two-finger gripper and carries 2 kg. The body can move more than 50 cm vertically, so tasks at different heights are possible. The robot is built from components used in cobots and AMRs. Coupang is trialling it in a fulfilment centre. The data come from product-launch reporting rather than a full datasheet.
