Hi, I am currently going through the tutorial of Kokubi, but I cannot even finish the keyboard teleoperation.

I have connected the usb, and checked the connections:

ubuntu@tegra-ubuntu:~$ lsusb Bus 002 Device 009: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 002 Device 004: ID 1d27:0601 ASUS Bus 002 Device 003: ID 046d:c534 Logitech, Inc. Bus 002 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:07dc Intel Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Obviously the first one shows kobuki is connected.

However,

ubuntu@tegra-ubuntu:~$ ls -n /dev | grep kobuki ubuntu@tegra-ubuntu:~$

and I run: roslaunch kobuki_node minimal.launch --screen got:

NODES / diagnostic_aggregator (diagnostic_aggregator/aggregator_node) mobile_base (nodelet/nodelet) mobile_base_nodelet_manager (nodelet/nodelet)

Thank you, Bin
