First Robotics Assignment - getting close!!

Here you can see the scenario. The robot has to take one cube of each color an put them in line on the right side. At the end there should be 12 lines of cubes of different colors on the right side.










Here are two robots. At the bottom is one following the black line and sensing distance to detect the presence of cubes.
Above is one trying to load some cubes.
Each robot has to do the work by itself, but while we try each group tries its robot on different places.












A look from above. The robot on the left is sensing the color of the cubes and the robot on the right is following the black line.










 This robot took 3 cubes and is taking them to the other side.

Export to Excel with spreadsheet gem

While using the spreadsheet gem to export data to a Microsoft Excel file I encountered various problems and lack of proper documentation forced me to dig pretty deep.

Keep sidekiq running using monit

As an application grows it starts taking care of more and more work. At some point the first task comes that needs to be processed in background and one of the usual suspects for ruby is sidekiq.

Install monit Depending on your package manager this may differ: apt-get install monit yum install monit brew install monit Configure monit Edit  /etc/monit.conf or  /etc/monitrc Uncomment(or add) these lines: set httpd port 2812 and use address localhost allow localhost Add sidekiq entry Create the file /etc/monit.d/sidekiq.monitrc with: check process sidekiq_application_production0 with pidfile /path/to/shared/tmp/pids/side
