Chapter 1 :GGGetting ready
The CRX10 is an autonomous mobile robot platform for education
in elementary, middle or high schools, training and research.
CRX10 supportsMSRDS, SPL (Simple Programming Language), AVR (C languages)
and Android programming languages.
· Clean and modern design
· Microsoft VPL visual programming language support
· Voice recognition, joystick and other various services are represented graphically via VPL
· 9 robot activities or services in VPL
· 2 wheel to 4 wheel transformable structure, for driving stability robot
has double wide wheels
· Robots can roll over bumps. Maximum slop is about 15 degree.
· 3 rubber ring-shaped coverings t around a wheel rim to protect it
and enable a close contact with the ground. For easy coverings maintenance
there are special“U” type notches on rims.
· Audio source tracking, autonomous obstacle avoidance, line tracing
· 64 LED-based display
· 4 user programmable function buttons
· Built-in rechargeable lithium-ion battery
· Detachable payload tray

System Block Diagram
Overall structure is divided into ATmega128 and ATmega88, there is a serial
port (RS232c) for wired connection and Bluetooth module for wireless com-
munication. For communication robot uses SPI protocol. The control board uses
external 9V DC power supply, for powering each module separately control
board includes 5V line and 3.3 V regulator. I/O and A/D operates separately
from processor (128, 88).
First, user should download rmware via USB to ISP communication cable and
then set up Dot Matrix, Buzzer, DC Motor Drive, Encoder, Function buttons (5
I/O modules), IR and PSD sensor (2 A/D models). Atmega 88 processor can’t be
edited by the user. It contains default LED (1 I/O module) and 4 A/D modules
(Mice, Battery check, IR and circuit check setups).
