Elmer and Elsie (ELectroMEchanical Robot, Light-Sensitive) were two electronic robots that were built in the late 1940s by neurobiologist and cybernetician William Grey Walter. They were the first robots in history that were programmed to "think". [1] Elmer and Elsie were often labeled as tortoises because of how they were shaped and the manner in which they moved. They were capable of phototaxis which is the movement that occurs in response to light stimulus. [2]
Elmer and Elsie, or the "tortoises" as they were known, were constructed between 1948 and 1949 using war surplus materials and old alarm clocks. They had a single light or touch sensor hooked up to two different paths that ran two different motors acting as two separate neuron brains. [1] The robots had a plastic shell which was phototropic in that it could follow light and act as a bumper sensor. [3]
The robots were designed to show the interaction between both light-sensitive and touch-sensitive control mechanisms which were basically two nerve cells with visual and tactile inputs. These systems interacted with the motor drive in such a way that the tortoises were actually finding their way around obstacles. [4]
In one experiment a light was placed on the nose of one of the tortoises. It appeared that the robot was looking at itself in a mirror. Its light began flickering and the robot started shaking as if excited to see itself in the mirror. Walter argued that if this behavior were seen in an animal it "might be accepted as evidence of some degree of self-awareness." [3]
Elmer and Elsie inspired later generations of robotics researchers such as Rodney Brooks, Hans Moravec and Mark Tilden.[ citation needed ] Rodney Brooks' "Intelligence without Representation" is in many ways a modern take on Elmer and Elsie. Modern replicas of the tortoises may be found in the form of BEAM robotics. [4] An original tortoise is on display in London UK in the Science Museum's Making the Modern World gallery. In 1995, one was replicated by Owen Holland, of the University of the West of England, which used some of the original parts. An original tortoise as seen at the Festival of Britain is in the collection of the Smithsonian Institution. [3]
A robot is a machine—especially one programmable by a computer—capable of carrying out a complex series of actions automatically. A robot can be guided by an external control device, or the control may be embedded within. Robots may be constructed to evoke human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics.
An autonomous robot is a robot that acts without recourse to human control. Historic examples include space probes. Modern examples include self-driving vacuums and cars.
A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century.
An industrial robot is a robot system used for manufacturing. Industrial robots are automated, programmable and capable of movement on three or more axes.
Cog was a project at the Humanoid Robotics Group of the Massachusetts Institute of Technology. It was based on the hypothesis that human-level intelligence requires gaining experience from interacting with humans, like human infants do. This in turn required many interactions with humans over a long period. Because Cog's behavior responded to what humans would consider appropriate and socially salient environmental stimuli, the robot was expected to act more human. This behavior also provided the robot with a better context for deciphering and imitating human behavior. This was intended to allow the robot to learn socially, as humans do.
Lego Mindstorms is a discontinued line of educational kits for building programmable robots based on Lego bricks.
BEAM robotics is a style of robotics that primarily uses simple analogue circuits, such as comparators, instead of a microprocessor in order to produce an unusually simple design. While not as flexible as microprocessor based robotics, BEAM robotics can be robust and efficient in performing the task for which it was designed.
William Grey Walter was an American-born British neurophysiologist, cybernetician and robotician.
Behavior-based robotics (BBR) or behavioral robotics is an approach in robotics that focuses on robots that are able to exhibit complex-appearing behaviors despite little internal variable state to model its immediate environment, mostly gradually correcting its actions via sensory-motor links.
An alarm clock or alarm is a clock that is designed to alert an individual or group of people at a specified time. The primary function of these clocks is to awaken people from their night's sleep or short naps; they can sometimes be used for other reminders as well. Most alarm clocks make sounds; some make light or vibration. Some have sensors to identify when a person is in a light stage of sleep, in order to avoid waking someone who is deeply asleep, which causes tiredness, even if the person has had adequate sleep. To turn off the sound or light, a button or handle on the clock is pressed; most clocks automatically turn off the alarm if left unattended long enough. A classic analog alarm clock has an extra hand or inset dial that is used to show the time at which the alarm will ring. Alarm clock functions are also used in mobile phones, watches, and computers.
The Sharp Wizard is a series of electronic organizers released by Sharp Corporation. The first model was the OZ-7000 released in 1989, making it one of the first electronic organizers to be sold. The name OZ-7000 was used for the USA market, while in Europe the device was known as the IQ-7000.
A passive infrared sensor is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications.
An analog robot is a type of robot which uses analog circuitry to go toward a simple goal such as finding more light or responding to sound. The first real analog robot was invented in the 1940s by William Grey Walter. The name of these robots were Elmer and Elsie. The original circuitry was developed using two vacuum tubes and a photocell to search and follow a light. Recently a kind of analog robots was developed by Mark Tilden.
A motion detector is an electrical device that utilizes a sensor to detect nearby motion. Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. They form a vital component of security, automated lighting control, home control, energy efficiency, and other useful systems.
The Omnibot (オムニボット) is a toy robot originally manufactured by Tomy in the mid-1980s. The name then came to apply to the successful line of robots manufactured by the company. The initial Omnibot was announced with expectations of restoring popular interest in robots, at a time when it was becoming obvious that robots with advanced AI such as R2-D2 were still a long way away. A more advanced version of the Omnibot was called the Omnibot 2000 and did not have a plastic bubble over its head. With the success of the Omnibots, the Omnibot range quickly expanded. After the video game crash of 1983 and its debilitating effect on the nascent home electronics industry, the Omnibot faded away but it was revived in the early 2000s. The latest version of the Omnibot is the i-SOBOT.
The history of robots has its origins in the ancient world. During the industrial revolution, humans developed the structural engineering capability to control electricity so that machines could be powered with small motors. In the early 20th century, the notion of a humanoid machine was developed.
Botball is an educational robotics program that focuses on engaging middle and high school aged students in team-oriented robotics competitions. Thousands of children and young adults participate in the Botball program. It has been active since 1998 and features a robotics curriculum which focuses on designing, building and programming a pair of autonomous robots. Teams use a standardized kit of materials, document the process and then compete in a tournament in which the challenges change annually. All materials in the kits are exactly the same for every team around the world, so there are no unfair advantages. Botball teams are mostly based in the United States with over 300 teams and local tournaments in more than a dozen regions. In recent years it also holds an annual Global Conference on Educational Robotics (GCER), with an international tournament that attracts teams all over the country as well as from Mexico, Austria, China, Uganda, Poland, Qatar, Kuwait, Egypt, and many others.
Robotic sensing is a subarea of robotics science intended to provide sensing capabilities to robots. Robotic sensing provides robots with the ability to sense their environments and is typically used as feedback to enable robots to adjust their behavior based on sensed input. Robot sensing includes the ability to see, touch, hear and move and associated algorithms to process and make use of environmental feedback and sensory data. Robot sensing is important in applications such as vehicular automation, robotic prosthetics, and for industrial, medical, entertainment and educational robots.
Tekno the Robotic Puppy is a popular electronic robotic toy which originally launched in late 2000. Tekno sold more than 7 million units in its first season and went on to sell more than 40 million units in its original 4 years of production. The worldwide popularity for Tekno led to prominent awards and widespread media coverage which included newspaper articles, television and film appearances, and a stand-alone feature on the cover of Time magazine.
The Ladybird of Szeged or Ladybug of Szeged is an early robot which was developed in Hungary at the Cybernetics Laboratory of the University of Szeged (SZTE) between 1956 and 1957. The roughly hemispherical machine has a red shell with black dots, resembling a ladybird, hence its name. The Ladybird is one of the first Hungarian robots, and the first robotic animal ever constructed. It was designed and built by Dr. Dániel Muszka, with the main intention of emulating Pavlovian conditional reflexes in a machine.
