Which of these is NOT one of the early robots?

• A. Wabot-2 capable of playing the organ
• B. Hexapodal robot named Genghis
• C. The SCARA, Selective Compliance Assembly Robot Arm
• D. The Honda ASIMO

Answer: (D)

Early robots came from the first decades of robotics, focusing on basic manipulation, simple motion, and task-specific automation. The organ-playing Wabot-2 shows how early experiments explored robots interacting with human activities, while a hexapod robot named Genghis demonstrates legged locomotion as another early exploration beyond wheels, and the SCARA arm represents an early, practical industrial robot designed for fast, planar assembly tasks.

Honda ASIMO, introduced around 2000, is a later development with advanced sensing, autonomous navigation, and sophisticated humanoid locomotion. It reflects the next era of robotics after those foundational demonstrations, which is why it isn’t considered one of the early robots.
