SapienIRCtl provides an IR control of robot devices that are normally controlled by hand-held remote control, such as RoboSapien V1, V2, or i-Sobot. It is a follow-up on a similar project where these robots can be controlled using LEGO serial IR tower, however, these devices are not produced anymore, and they are not very suitable, since the host PC must control the whole signal. In our case, the ATtiny45 receives the code to be send to the robot over USB line, and then generates the signal using two timers, one used for PWM and one used for the 1200Hz/1800Hz time-unit frequency interrupt. We used the low-cost 8-pin ATtiny45, which seems to be sufficient

This device is derived from AVRUSB project

After the device is plugged to USB port for the first time, you need to tell Windows to use a specific driver that is located in the commandline/windows-driver subdirectory. Once the driver is installed, you can use the commandline utility sapienirctl.exe to emit the RoboSapien V1, RoboSapien V2, and i-Sobot codes.

You can download the last version of the release from CVS release directory, and check for the last CVS files in the CVS repository.

This device can in principle control wide range of remotely controllable devices - such as TV sets, HiFi, other remotely-controlled robots, etc.


We have some spare devices that we can send you for the cost of parts that is about 15 EUR. Please let us know at ppetrovicZavinac.gifacm.org.
