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.
While useful for many wheeled or tracked vehicles, traditional odometry techniques cannot be applied to mobile robots with non-standard locomotion methods, such as legged robots. In addition, odometry universally suffers from precision problems, since wheels tend to slip and slide on the floor creating a non-uniform distance traveled as ...
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.
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 ...
A configuration describes the pose of the robot, and the configuration space C is the set of all possible configurations. For example: If the robot is a single point (zero-sized) translating in a 2-dimensional plane (the workspace), C is a plane, and a configuration can be represented using two parameters (x, y).
Honda humanoid robots, whose locomotion is based on ZMP feedback: [3] P2, the first self-regulating, two-legged walking robot prototype released in 1996. Asimo, a humanoid robot of worldwide fame developed commercially from 2000 to 2022. HUBO, a walking humanoid robot developed by KAIST that won the DARPA Robotics Challenge in 2015.
These four-legged military-grade machines, developed by Philadelphia-based Ghost Robotics, “are designed to navigate challenging terrains, including sand, rocks, and human-made environments like ...
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.
