ICStation First Smart Car: Android Smart Phone Bluetooth Remote Control Intelligent Smart Car 51 MCU

At the beginning of the new year, robot/Smart Car hobbyists and students (like all of you) about engineering, science and technology are busy with preparing for the robot competitions now.
It’s the great time to show the world your imagination and potential now.
ICStation R&D department has just finished this obstacle avoidance intelligent smart car which based on the STC89C52 MCU. It features with the function of obstacle avoidance,  infrared remote control and Bluetooth remote control system. It improves a lot on the usage of this intelligent smart car via the connects of various modules and controller.
BTW, this is just a sample which based on 51 MCU for your reference. You also can use other MCU to build your own gear. If you like 51, just leave us your email address to get the testing code.
