1. Smart phone Nexus 5
CPU: Qualcomm SnapdragonTM 800, 2.26GHz
RAM: 2 GB
Sensors: GPS, Gyroscope, Accelerometer, Compass, Proximity/Ambient, Light, Pressure, Hall Effect
Android 4.4
This smart phone is very powerful. It has everything for image recognition, fast CPU, huge DRAM, open-source OS Android. It can detect ball and net very quickly at real time. So the Robot can respond as fast as possible. In addition, embedded sensors can give the Robot enough information for accurate position control.
Since it is Android system, plenty of free samples and free source code can be found in open source world. Unlike iPhone, Nexus 5 is free to program on it. User can get free development environment tools from internet.
OpenCV is open source and standard image recognition software, it has reach functions for object detection and widely used by commercial field. It is powerful but simple for programmer.
2. BeagleBone Black Development Board
CPU: 1GHz AM3359 Sitara ARM Cortex-A8
RAM: 512MB DDR3
CAN Bus
Wifi
6 Timers
It is ARM9 CPU, running Linux OS. With its WI-FI, it can communicate with smart phone through TCP/IP protocol. <br>
Six Timers IO control 6 servos, 4 of them for arm and 2 for smart phone panning and tilting control.
CAN BUS is for eZ430 board communication to control 2 rear wheels DC motors.
With process programming, it can search ball by head servos panning and tilting, moving arm to kick and grab ball and driving the Robot.

ReplyDeleteShould you need suggestions for how to keep up your ball bearings, look at these top 10 facts that you may not understand in regards to tolerances and performance. Nowadays, a business wouldn’t be complete without these cards. Every company intends to conduct an advertising plan which fits their objective.
Technology has gotten so advanced that LED lights are now able to be attached to several kinds of piercings. In all instances, these systems are offered in uniprocessor versions too. Uniprocessor and SMP systems need different programming methods to attain maximum performance. Audi A6 navigation system appears to be among the most fashionable in dash navigation today. It isn’t unusual for a computer to deliver a few beep sound, which is normally very precise. IBM’s LAPTOP was not patented.
