Wireless Servo Widgets allow you to control up to 64 slaves, with each slave controlling up to six R/C type servos. In addition, each slave can return 3 analog input values to your Raspberry Pi. Slaves have a range of about 50 feet from the master. Use them for home automation, robotics, model train controls, or whatever you want!
Free Software for controlling your servo widgets. Python classes, tutorials and HTML5 demo applications for your Raspberry Pi. Note: the widgets will work with most hosts, Windows, Mac and Linux.
I'm working on a more advanced, longer range version of this project, you can find details of it here.
