This paper describes an ongoing project to move a simple humanoid robot, without an advanced embedded electronics. We used another wheeled mobile robot which already has a locating system and is equipped with a camera. We will locate the humanoid in the environment based on images, and then take the necessary actions to move it. In the future, we will also move the robot with the camera, so it ...

Parameter identification scheme and discrete-time adaptive sliding-mode controller applied to Pioneer 3-DX wheeled mobile robot (WMR) are presented in this paper. The dynamical model for mobile robot with one pair of active wheels, time–varying mass and moment of inertia have been used in slidingmode control. Two sliding-mode controllers corresponding to angular and position motion have been de...

An autonomous mobile robot should find feasible trajectories in order to avoid collisions with obstacles in its environment. This ability to plan collision-free trajectories requires two major aspects: modulation and generation of trajectories. This is especially important if temporal stabilization of the generated trajectories is considered. Temporal stabilization means to conform to the plann...

This technical note presents a behavior-based navigation method for a mobile service robot with a three-wheeled omnidirectional mobile platform. A heuristic fuzzy Kohonen clustering network (FKCN) is presented to obtain laser area weights and desired robot motion heading for all types of indoor environments. An efficient behavior-based navigation structure is then proposed to merge the heuristi...

Positioning of mobile robots basically calculated using odometry information. Odometry from the wheel’s encoder is mostly used for simple and inexpensive implementation for determining the relative localization of a mobile robot. This paper deals with the estimation of better relative localization of a two wheeled differential drive robot by means of odometry by considering the influence of par...

Autonomous and teleo erated mobile robots require an ccurate knowledge of their spatial location in order to accomplish many tasks. Many mobile robots make use of dead reckoning navigation because of its simplicity, low cost and robustness. Although dead reckoning navigation has been used for centuries for ships and wheeled vehicles, the application to a walking machine is novel. Since walking ...

The structure of OmniKity-I (OK-I), the miniature omni-directional mobile robot, and its kinematics and dynamics models are presented. OK-I has three DOFs in the plane. A conventional two wheeled mobile robot (2-WMR) serves as the base of OK-I for translational motion. The robot body is on top of the base. The third motor controls angular motion of the body as the base turns according to the tr...

This paper studies distributed rendezvous strategies for multiple nonholonomic wheeled mobile robots with the aim of testing their practicality on real robots. We investigate control strategies which use just bearing-only or range-only measurements and do not need inter-robot radio communication to share the measurements. For the bearing-only case, two control laws proposed in our previous stud...

This paper presents a simulation framework for evolution on uneven terrains for a wheeled mobile robot such as a synchronous drive robot. The framework lends itself as a tool capable of solving various problems, such as forward kinematic based evolution, inverse kinematic based evolution, path planning and trajectory tracking. This framework becomes particularly useful when we understand that t...

Over the last few years there have been great developments and improvements in the mobile robotics field, oriented to replace human operators especially in dangerous tasks, such as mine-sweeping operations, rescuing after earthquakes or other catastrophic events, fire-fighting operations, working inside nuclear power stations and exploration of unknown environments. Different locomotion systems...
