Ctesibius, a Greek inventor and mathematician in Alexandria, Ptolemaic Egypt during 2000 BCE
, the Greeks divided the time between sunrise and sunset into 12 day hours, and the time between sunset and sunrise into 12 nighttime hours. The time between sunrise and sunset is much shorter during the winter. He fixed this problem by marking the hours with curved lines on a drum. He then created a mechanism that reset the hour pointer every day ,also turned the drum so the lines matched the season.
The boat was four feet long having three antennas with small light bulbs to be easily seen at night
Inside the boat's hull, there was an electric motor driving both the propeller and rudder, a storage battery and a mechanism for receiving the radio signals sent from the control box.
The first mobile robot with the ability to perceive and reason about its surroundings
The subject of SRI's Artificial Intelligence Center research from 1966 to 1972, Shakey could perform tasks that required planning, route-finding, and the rearranging of simple objects.
The project started in 1993 by MIT. Their aim was to investigate the possibility of constructing a robotic submarine that could reproduce the way tunas swim and see if they could find a superior system of propulsion for the AUVs.
Shigeo Hirose´s Soft Gripper robot can conform to the shape of a grasped object, such as a wine glass filled with flowers. The design Hirose created at the Tokyo Institute of Technology grew from his studies of flexible structures in nature, such as elephant trunks and snake spinal cords.
Roomba has a set of basic sensors that enable it perform its tasks.
the Roomba is able to change direction on encountering obstacles, to detect dirty spots on the floor, and to sense steep drops to keep it from falling down stairs
Kismet is a robot head made in the late 1998 in MIT by Dr. Cynthia Breazeal as an experiment in affective computing; a machine that can recognize and simulate emotions
Facial expressions are created through movements of the ears, eyebrows, eyelids, lips, jaw, and head
1999
Personal Robots released the Cye robot. It performed a variety of household
chores, such as delivering mail, carrying dishes, and vacuuming etc. It was
created by Probotics Inc
1985
Created by the General Robotics Corp. the RB5X was a programmable robot
equipped with infrared sensors, remote audio/video transmission, bump
sensors, and a voice synthesizer. It had software that could enable it to learn
about its environment
2000
Sony unveiled the Sony Dream Robots (SDR) at Robodex. SDR was able to
recognize 10 different faces, expresses emotion through speech and body
language, and can walk on flat as well as irregular surfaces. Image of QRIO [
