r2d2 roomba

What's this?"Roomblock" is a robot platform consists of a Roomba, a Raspberry Pi 2, a laser sensor (RPLIDAR) and a mobile battery.The mounting frame can be made by 3D printers. ROS navigation system enable to make a maps of rooms and use it to reach to the goal autonomously.Who need this?Anyone want to learn the cutting-edge technologies of robotic navigation, mapping, and autonomous driving. This robot can is built easily and lower cost than other co

, namely the ability to automate virtual and reality. If you have never created a robot, do it. At least learn to use LEGO Mindstorms or play with an Arduino board. Check your daily tasks to see which ones can be completely or partially automated. Automation has made great strides in the family life, and can even DIY the system like insteon.

The best way to explain permission control is to use some specific instances instead of boring concepts. Han is the ship captain of the Millennium Falcon ship, and Chewie is his second ship carrying passengers including Luke, Obi-Wan, R2D2, and C3PO. han needs to define an access permission for each compartment on the spacecraft, including cockpit, power compartment, rest compartment, and weapon compartment.
