Further Development & Programming
The Jaguar Control program
The Jaguar Control program is written with Visual Studio 2010 (in C#) under .Net 3.5 framework.
The control program uses the supporting components and libraries that should have been installed when you
install the control program from the installation CD:
AXIS Media Control Library Set These are the camera control component for the AXIS Mini Camera
(P/N: AXCAM-A) used for Jaguar robot. Please refer to “AXIS Media Control SDK Help” for detail.
Motion Control/Sensing System
Based on the protocol, you could develop your own program for any operation system. You could request
protocol sample code from Dr Robot using C++/Java, Matlab, and ROS. You should also contact Dr Robot with
any questions regarding protocol.
The communication port is connected at Ethernet module-I port 1.
Control program will connect to this board at 192.168.0.60, port 10001 by TCP socket.
Laser Scanner
Laser Ranger sensor (4m version, URG-04LX) is connected to Ethernet module–1 port 2 after voltage level
conversion. You could access the sensor data via TCP socket at port 10002 with IP 192.168.0.60.
Default settings for the serial port are: 19200, 8, N, 1, no flow control, TCP, port number 10002
Date and communication protocol could be found in “URG-04LX commspec_eg.pdf”.
GPS
GPS sensor output interface is RS232 serial port, and connected to Ethernet module-2 port 2 after voltage level
conversion. You could access the sensor data via TCP socket at port 10002 with IP 192.168.0.61.
Default settings for the serial port are: 115200, 8, N, 1, no flow control, TCP, port number 10002
NMEA 0183 sentence is described in file “GPS18x_TechnicalSpecifications.pdf”. GPS configuration tool is
