Odometry is the use of data from motion sensors to estimate change in position over time. It is used in robotics by some legged or wheeled robots to estimate their position relative to a starting location. This method is sensitive to errors due to the integration of velocity measurements over time to give position estimates.
Legged robots are a type of mobile robot which use articulated limbs, such as leg mechanisms, to provide locomotion. They are more versatile than wheeled robots and can traverse many different terrains, though these advantages require increased complexity and power consumption.
Visual odometry is the process of determining equivalent odometry information using sequential camera images to estimate the distance traveled. Visual odometry allows for enhanced navigational accuracy in robots or vehicles using any type of locomotion on any [ citation needed ] surface.
A six-legged walking robot should not be confused with a Stewart platform, a kind of parallel manipulator used in robotics applications. Beetle hexapod. A hexapod robot is a mechanical vehicle that walks on six legs. Since a robot can be statically stable on three or more legs, a hexapod robot has a great deal of flexibility in how it can move.
RHex is an autonomous robot design, based on hexapod with compliant legs and one actuator per leg. A number of US universities have participated, with funding grants also coming from DARPA . Versions have shown good mobility over a wide range of terrain types [ 1 ] at speeds exceeding five body lengths per second (2.7 m/s), climbed slopes ...
Underwater walking robot, using Klann leg linkages in laser-cut and anodised aluminium. [1] The Klann linkage is a planar mechanism designed to simulate the gait of legged animal and function as a wheel replacement, a leg mechanism. The linkage consists of the frame, a crank, two grounded rockers, and two couplers all connected by pivot joints.
BigDog is a dynamically stable quadruped military robot platform that was created in 2005 by Boston Dynamics with the Harvard University Concord Field Station. [1] It was funded by the U.S. Defense Advanced Research Projects Agency (DARPA), but the project was shelved after the BigDog's gas engine was deemed too loud for combat.
Legged locomotion studies began in 1878, when a publication of stop-motion photographs of mammals was posted in Scientific American. The first robot capable of actual "running" was created in 1980. The field was greatly enhanced when the Leg Lab at Carnegie Mellon University was established, producing many running robots.
