The XBC, the RCX, and the Handy Board use Interactive C. IC 8 is provided as a service to educators and the general public. The software was used for the the Botball Educational Robotics Program prior to 2009. We invite you to download and use the software, but please note that it is not actively supported. KISS Institute welcomes your suggestions for added features as well as bug reports. At this time, IC Supports the Xport Botball Controller (XBC), the Handy Board with Expansion Board, the Sumo11, and the Lego RCX using the serial IR tower only. There is currently no support for the USB IR tower.
