ROS is a community effort, with many institutions contributing to its development. Much of the underlying platform is being developed by Willow Garage and Stanford.

ROS is a robot operating system originally developed (2007) in the Stanford Artificial Intelligence Laboratory in support of the Stanford AI Robot (STAIR) project but now (as of 2008) developed primarily by Willow Garage, a robotics research institute/incubator. It is free for commercial and research use under a BSD license. The library runs primarily on Linux but is intended to be cross-platform for Mac OS X and Windows. ROS provides standard operating system services such as hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management. It is a graph based architecture where processing takes place in nodes that may receive, post and multiplex sensor, control, state, planning, actuator and other messages.

Before read the rest article/tutorial, please watch the video first.. . See the robot’s movement and i’t speed. This is very great…!

You may see the video here.

This line follower robot is very small and simple. This robot is running fast and follow the line very smoothly.

Mechanics

Wowwee’s Roboreptile is an often startling robotic toy that, once you get the hang of its wonky controls, is actually pretty fun. Like other Wowwee robots, there’s a preprogrammed animation that goes off when it is first powered up. It’s impressive: growling, snapping jaws and a whipping tail. In short, Roboreptile looks like something out of the future and moves like something out of the past.

The Roboreptile has infrared “vision” sensors where its eyes would be and stereo “hearing” sensors on the sides of its face. Its sounds, though a bit tinny, are menacing. During a tail swipe, it lets out a sort of Eagle cry, harkening back to the shared avian/reptile ancestry.

Controlling the Monster
Controlling the Roboreptile with the remote is a bit of a strain. First, because the remote uses an infrared beam and the pick-up sensor is located in its head. You won’t be able to control it from far away, and it’s difficult to control while walking away from you.

Overview

Mobile robots have the capability to move around in their environment and are not fixed to one physical location. In contrast, industrial robots usually consist of a jointed arm (multi-linked manipulator) and gripper assembly (or end effector) that is attached to a fixed surface.

Mobile robots are the focus of a great deal of current research and almost every major university has one or more labs that focus on mobile robot research. Mobile robots are also found in industry, military and security environments. They also appear as consumer products, for entertainment or to perform certain tasks like vacuum cleaning or mowing.

Robosapien Version 2 is the next generation of Robosapien technology and personality from Wowwee. This new member of the robotic family comes with more advanced dynamic motion, interactive sensors, new program functions, speech capability, and a personality all his own. It’s clear from the start that he enjoys bowling, dancing, and having conversations.

Movement
RobosapienV2 is able to walk forward in four different styles, or gaits. He normally uses his IR vision and touch sensors built into his feet and hands to avoid obstacles, but if put into bulldozer mode, he will walk forward or backward and try to push his way through anything.

Beyond controlling him manually with the included remote controller, RobosapienV2 can explore his environment independently in free roam mode. You can also direct his movements by using the remote’s targeting feature–just point the beam to a spot on the floor and he will walk toward it.

RobosapienV2 has been designed with a full range of motion. He can turn his head just like humans. So, too, can he turn at the hips and can move them forward and back and from side to side. RobosapienV2 can move each arm independently, and his hands can grab, pick up, and throw light objects, such as the included bowling balls and pins. He even comes preprogrammed with a selection of dance moves.
