IMU-based Localization And Slip Estimation For Skid-Steered ...
Most dead-reckoning-based robot localization work do not consider the wheel slip. Second, we present a low-cost IMU-based localization and slip estimation scheme for skid-steered robots. Such an on-line estimation scheme allows us to further develop a slip-based robot control system that can be used in varying ground surface conditions [5]. ... Get Doc

Multi-Robot Motion Planning By Incremental Coordination
Decoupled approach of multi-robot motion planning [3]. In the rst phase of the basic decoupled approach, a path for each robot is computed individually ignoring other robots. Then in the second phase robot motions are coordinated such that inter-robot collisions are avoided. The second phase, the key phase in the decoupled planning approach ... View Document

Applying The Boe-Bot Digital Encoder Kit (#28107)
With a simple optical sensor, the wheels themselves could become ideal encoder disks. But first, some math. The Theory Moving Assume a robot with two opposing drive wheels, each of diameter d and distance w apart. Also assume that as each wheel turns, an encoder outputs n equally-spaced pulses per revolution. Each of ... Doc Retrieval

Servomechanism - Wikipedia
In control engineering a servomechanism, sometimes shortened to servo, is an automatic device that uses error-sensing negative feedback to correct the action of a mechanism. It usually includes a built-in encoder or other position feedback mechanism to ensure the output is achieving the desired effect. ... Read Article
