HCR-Home Care Robot
HCR-Home care robot is an open source robot project.
It aims to develop an affordable domestic mobile robot platform which can validate various robotics technologies such as Human machine interface, navigation, localization.
At this moment, it has just finished the mechanical design. The electricity module is still under development. But I am trying to use several arduino type of MCU as the low level hardware control, and uses a normal laptop or netPC as the main control unit which can do more advance work such as voice recognition, vision, .etc.
This project is initially proposed in a chinese robotics community www.roboticfan.com. And I bought one of their platform to start with.
Figure: A Lead-acid battery is mounted
Figure: After assembly, still can not move yet, since no MCU.
This is the electrical connection diagram. Uses two arduino, one is used as a sensor interface board, another is used as a master, do some post processing of the sensor signal, package them and send them back to PC.
