Data School 3 - Image Index | Yenra Robots on a Blackboard: A scene featuring three small robots standing in front of a blackboard covered in equations and mathematical symbols. The robots are crafted from square metal blocks with round black eyes and have a similar body shape, but each one is unique due to their different colors. The middle robot's left arm appears slightly bent towards its body, giving it the illusion of waving. The background consists of various objects, including cogs and wires that contribute to the overall steampunk aesthetic. The atmosphere suggests an educational or scientific setting where robots are engaged in learning or teaching about mathematics.
