Motor Noise
If your robot’s motors seem to be trying to move and are creating a disturbing noise,
check the battery meter in the lower left corner of the RCC screen. If the battery is low,
turn the robot off and charge the battery.
Wireless Network Disconnect
If your wireless link between your robot and your remote computer has disconnected do
the following:
1. Click on the Settings button.
2. Select the Remote Control tab.
3. Either the Allow remote control of this instance or the Control robot at this IP
address option must be selected.
4. Click on the Reset the network connection now button.
5. Click on the Ok button. This signals the two computers to reestablish the connection.
You may have to repeat this process more than once to get a connection.
This problem is generally an issue with your wireless network, not your robot. If you
continue to have problems, contact your wireless card manufacturer to troubleshoot your
system.
Frozen Robot
Rarely the ER1 module will freeze, and you will need to reset the internal memory in the
module in order to make the robot move. To do this, follow these steps:
1. Make sure the laptop is on, and the software is not running.
2. Turn off the ER1 Battery.
3. Unplug the USB cable from the laptop.
4. Turn on the ER1 battery.
5. Plug the USB cable back into the laptop.
6. The internal memory should now be reset and the robot should function properly.
Camera Shuts Off When Launching RCC/Unplugging Power Supply
This issue has been documented on Hewlett-Packard laptops. This seems to happen due to
the HP laptop's handling of power management. When you unplug the laptop from the
wall outlet and Windows' power management scheme is set to 'Laptop/Portable', power to
the USB bus (and all devices on the system) gets reduced significantly. Since the Kritter
Cam requires the full 500ma of power, there is not enough to keep it functioning.
