Troubleshooting Guide; Qbot Drive Or Direct Drive Commands Aren't Responding Or Are Causing The Robot To Move Incorrectly, Or The Qbot Bump Sensor Inputs Are Not Functioning - Quanser qbot User Manual

Quanser Qbot: User Manual
QUARC > Options and navigate to the Code Generation page and select C++ under
Language. The LLVM-GCC cross-compiler (default compiler for the quarc_linux_verdex
target type) will not compile models using the vision blocks. The compiler can be changed
under the QUARC > Options window on the Code Generation > QUARC page. Selecting
Native GCC will use the compiler on the Verdex, which is slower than the cross-compiler
since it downloads the generated code and compiles natively on the Gumstix. To utilize a
cross-compiler, the CodeSourcery Lite cross-compiler can be used. Use of the
CodeSourcery Lite cross-compiler results in much faster compilations, but requires that the
CodeSourcery Lite cross-compiler be installed (see the Installing CodeSourcery help page in
the MATLAB help for details on downloading and installing CodeSourcery).

6. Troubleshooting Guide

For any issue, the first and easiest troubleshooting solution on any electronic device is to re-
boot the device. Turn off the Qbot, then turn it back on again. For troubleshooting any prob-
lem with the Qbot, it is always a good idea to open the QUARC console in case additional
information is printed to the console by going to the QUARC menu and clicking on "Con-
sole for all...". The console must be opened after the Qbot has booted and established a wifi
connection. If the console is opened successfully it establishes a connection to the target and
the console window has the title "QUARC Console for * at tcpip://182.168.1.xxx:17000",
where xxx corresponds to the IP address of the Qbot.

6.1. Qbot Drive or Direct Drive commands aren't
responding or are causing the robot to move incorrectly,
or the Qbot bump sensor inputs are not functioning.
1. Check that the Qbot wheels are retracted fully into the wheel bays. If any wheel is out of
its bay, then the Qbot will stop driving for safety reasons. Makes sure to operate the Qbot
on a hard, flat surface.
2. Turn off the Qbot and iRobot Create power and remove the jumper on the INT/EXT bat-
tery header on the Qbot. Turn on the iRobot Create and run the built-in demos and
troubleshooting steps found in the iRobot Create Owner's Guide supplied with your
Qbot. If the troubleshooting steps in the iRobot Create Owner's Guide show that the ro-
bot is working, then replace the INT/EXT battery jumper on the Qbot and continue. If the
iRobot Create demos do not work as expected, please contact iRobot technical support.
