2012-03-30 00:43:59 -0500 answered a question minimal.launch > constantly restarting vol2.

I think I got rid of it by not executing roscore!

What happens now is that dashboard opens with the first 2 buttons green and Breaks and batteries grey. when I click on breaks, it says: Cannot control breakers until we have received a power board state message

Also it gives the following log:

File "/opt/ros/electric/stacks/turtlebot_viz/turtlebot_dashboard/src/turtlebot_dashboard/power_state_control.py", line 111, in set_power_state self._char_cap = 0.8self._char_cap +0.2float(msg['Charge (mWh)'])
KeyError: 'Charge (mWh)' Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 14636, in <lambda> lambda event: event.callable(event.args, *event.kw) ) File "/opt/ros/electric/stacks/turtlebot_viz/turtlebot_dashboard/src/turtlebot_dashboard/turtlebot_frame.py", line 274, in new_dashboard_message self._power_state_ctrl.set_power_state(battery_status) File "/opt/ros/electric/stacks/turtlebot_viz/turtlebot_dashboard/src/turtlebot_dashboard/power_state_control.py", line 111, in set_power_state self._char_cap = 0.8self._char_cap +0.2float(msg['Charge (mWh)'])

Any ideas? please help! :)

Hi, I'm aware of the previous topic about it, but still know what to do. When I execute $ roslaunch turtlebot_bringup minimal.launch

I'm getting:

2012-03-29 05:22:13 -0500 answered a question Turtlebot Restarting Continuously

Hello, sorry, I don't understand the Answer. What do I need to run then if not minimal? The Bringup tutorial suggests minimal.launch too.

sudo service turtlebot start > does not work. It says that the process is running but sudo service turtlebot status > says it is not

Anyone? Thanks
