Quanser Qbot: User Manual

5.1. Setting up the Qbot

Follow these steps to setup the Quanser Qbot:
1. Insert the battery underneath the Qbot.
2. Press power button shown in Figure 4. This turns on both vehicle and Qbot
DAC/Gumstix.

5.2. Establishing Wireless Connection

In order to establish wireless communications between the host PC and the Gumstix embed-
ded computers, a wireless ad-hoc (peer-to-peer) network is used. Each Gumstix target is as-
signed a unique IP address between 182.168.1.20 and 182.168.1.254. A wireless adapter is
provided with the system for the host PC. The IP address of this wireless adapter must also
be a unique IP address that is not already used by any Gumstix computer or another host PC.
The host PC wireless IP address should be set to an unused value between 182.168.1.10 and
182.168.1.19. If you are setting up only one host PC, set the wireless IP address to
182.168.1.10. For additional host PCs, set their IP addresses by incrementing the last digit,
e.g., 182.168.1.11, then 182.168.1.12, etc.
1. Windows should detect a network called GSAH, an "Unsecured Computer-to-Computer
Network". Connect to it.
2. Open the Status of the wireless network, then click on Properties.
3. Under "This connection uses the following items:", scroll down to Internet Protocol
(TCP/IP), then double click on it.
4. Instead of obtaining an IP address of the computer automatically, enter the following:
IP address: 182.168.1.xxx (any unused number)
Subnet mask: 255.255.255.0
Default gateway: 182.168.1.xxx (same as IP)
5. The Gumstix can be pinged by typing "ping {IP of Gumstix}" in the Run box in Win-
dows. If the connection is successful you will see the ping replies in the command win-
dow. Note: you may need to disable Windows firewall to establish a connection.
5.3. QUARC – Quanser Real-Time Control
Simulink should have a new menu item called QUARC once QUARC has been installed.
Note: QUARC should be installed with beta library components selected since the
Qbot uses some QUARC components that are found in the beta library.
