3. Turn on the Qbot and open the VAL Read Sensors block in one of the supplied Simulink
models. In the VAL Read Sensors parameters under the "Other" channels, select the
bump sensors by typing [13000:13002]. Attach a scope or display block to the VAL Read
Sensors "Other" channels output and compile and run the model. Verify that the bump
sensors can be read by the Qbot computer by pressing the Qbot bumper and watch the
bump sensors signals go from 0 to 1 when pressed. If these signals do not change, then
open the Qbot lid by removing the four lid screws shown in Figure 16 and verify that the
Qbot computer is connected to the robot. Make sure the DB-25 connector is firmly in
place, replace and secure the Qbot lid, and retry the bump sensor test.

6.2. The model fails to build/connect or the QUARC
console does not successfully open.
1. Turn on the Qbot and look through the square window located on the lower right of the
Qbot lid. When the Qbot powers up, you will see an orange LED come on in the inner
cargo bay of the robot. After approximately 30 seconds, a blue LED will flash to indicate
the Qbot wifi is powering on, and is attempting to connect to another computer on the
ad-hoc wifi network. If the blue LED flashes and remains on, then the wifi module is
functioning and is able to find another node on the ad-hoc wireless network. If the blue
LED flashes and then turn off, the Qbot is not able to detect other nodes (e.g., the host
PC) on the ad-hoc wireless network. Check that the wifi adapter is inserted properly in
the host PC and is configured according to the network configuration procedure outlined
in this manual (System Setup\Establishing Wireless Connection). Verify that the host PC
is connected to the wireless ad-hoc (GSAH) network and try to successfully ping the
Qbot by going to the Windows Start → Run and typing "ping 182.168.1.xxx" (without
quotation marks), where xxx corresponds to the IP address of your Qbot. If the blue LED
