II. PMB5010 Multimedia Controller
II.1 Introduction
The PMB5010 Robot Multimedia Controller can be used as audio, video and wireless communication
processing unit for various robotic applications. Its onboard firmware makes the low level function
modules such wireless communication module transparent to the users. A host (e.g. PC, DSP, or
processor) will be used to communicate and control the PMS5005 for different applications through
the UART (serial) interface. The system can help robotic and AI researchers and developers focus on
the high level logic and algorithm designs, and avoid the hassle of writing low level device drivers,
standard control schemes and troubleshooting the electronic circuits. The ease of use, powerful
functionality and onboard intelligence can eliminate design risk, streamline hardware and software
development, and significantly shorten the time to delivery while effectively reducing the cost. Typical
applications include humanoid robot, legged robot, wheel-based robot, robot head and intelligent
home device.
