"After half a lifetime of dreaming about it, I’ve finally started building a robot. It’s based on a remote controlled tank, an Android mobile phone and a IOIO board which connects the two via USB."

"Lately I was busy in the hardware design of a personal robot named Chippu. It is an open source project and runs ROS, the same powerful code framework that runs on many robots like PR2. It is made as economical as possible. At present there is no on-board processing and it is done in a remote computer."

"Advancements in Javascript, node.js, have simplified communication between robot and user. Using two choice nodejs libraries, socket.io and johnny-five, you can quickly put together a system to control a robot using a web browser."

"Here is a method for making an encoder with two sensors for your application. If you only need speed sensing, you may want to skip down to the construction section. The important variables are the radius of the circle (r), the distance between the two optical sensors (s), and the number of divisions in the wheel (d). …."

"This is first in series of articles about project I’ve been building in my spare time since last Summer. Actually it all began when I was researching a topic of modeling human motion kinematics in order to create gesture recognition library for Kinect. This ties heavily into motion theory of robotic manipulators so I also glanced at some designs of robotic arms."

"Hi, I bought two small servo motors last month. I was thinking what I can do with this two servo, since it is only two in number. Then I asked this to my friend Achu Wilson and he suggested me to try a four legged two servo walker and he shown a youtube video in which some one demonstrating it. Then I also got interested to make some thing similar to that."

"…At this moment the robot can measure its speed and regulate its motors to keep a desired speed. This means that when the robot goes uphill it will recognise that its speed has dropped and will increase motor power and vice versa when it goes downhill. The regulation is currently nothing more than: if speed is faster than desired then decrease motor power with a constant amount…."

"All parts were developed separately. This allowed adjustments in the assembly as well as smaller changes in case the design of one or other part become required. The focus was on low cost and use of materials easily accessible in the local market."

"Loki builds upon the software of Seeker and Mr. Roboto, including remote control and diagnostics over WiFi, but adds more capable vision processing, speech recognition, indoor pathfinding (Using A*), basic Artificial Intelligence, and general refinement of the architecture."
