The 1st Mobile Robot: SHAKEY
• SRI: Stanford Research Institute (1966-1972)
• Camera (120x120x4)• laser range finder• Off-board computing (DEC
PDP-10 and 15)Goal: study the methods of
interaction with a complex environment

Early Robots: SHAKEY
• Problem: Move about and manipulate objects• Environment: Single room painted black and white • 3 level action
– Low level: Simple moving, turning, route planning– Intermediate level: Connecting low level actions
together to achieve more complex tasks– High level: To execute plans to achieve goals
given by the user. • STRIPS (Stanford Research Institute Planning
System) planner• What kind of control system is it?

Robotics Today
• Assembly and manufacturing
![Page 11: Lecture 19 Robots Past and Future.ppt](https://reader036.vdocument.in/reader036/viewer/2022062301/55cf8e51550346703b90d21a/html5/thumbnails/11.jpg)
Robotics Today
• Material Handling• Gophers (Hospitals, Security guards)• Hazardous environment (Chernobyl)

Robotics Today
• Surgery (brain, hips)
![Page 14: Lecture 19 Robots Past and Future.ppt](https://reader036.vdocument.in/reader036/viewer/2022062301/55cf8e51550346703b90d21a/html5/thumbnails/14.jpg)
Robotics Today• Tele-presence and virtual reality• Man-machine interface – emotional robots• Nursing and home care• Surgeons help, remote surgery• Home chores• Security and protection• Self-assembly• Autonomous vehicles• Sea and space Investigation• Entertainment and art• Toys (1min 45 sek)• Children playing with robot and two dogs (3 min 15 sec)

Key Issues
• Grounding in reality: not just planning in an abstract world • Situatedness (ecological dynamics): tight connection with
the environment • Embodiment: having a body • Emergent behavior: interaction with the environment • Scalability: increasing task and environment complexity• Humanoid robot (10 min)

Why is Robotics hard?
• Sensors are limited and crude • Effectors are limited and crude • State is partially-observable
– internal and external, but mostly external– Asimo and stairs (36 sec)
• Environment is dynamic – changing over time– full of potentially-useful information
