After opening TISensorBrowser solution there in no Monkey.Robotics. I unfortunately cannot add it:
Could not install package 'Monkey.Robotics 0.5.2'. You are trying to install this package into a project that targets 'portable-net45+wp80+MonoTouch10+MonoAndroid10+xamarinmac20+xamarinios10', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
I will be glad for help.
