Zachery Shivers and I rushed this project out in the past week for the TI MSP430 Ultra-low Power Challenge. What we’ve achieved so far is a secure wireless door lock that allows you to unlock your door remotely via your RF-enabled TI eZ-430 Chronos watch.

Abstract
Using the new TI eZ430-Chronos sport development watch, which is based [...]

This is quite an interesting algorithm that does mobile robot localization based on 2D laser scan.
I’ve looked at a few different methods to reliably and simultaneously localize and map environment for mobile robots. In particular, one can use Extended Kalman Filter (EKF) to deal with Gaussian error in robot motion and achieve fantastic results (at [...]

Introduction
This project is an attempt to implement a 3D visualization of simultaneous localization and mapping (SLAM) based on raw sensor data provided by the Player robotics framework.
This project is useful for both research and application purposes. Visualization of SLAM in research can help robotists better debug their robots. It can also provide much more information [...]
