SRV-1 / SVS Blackfin HTTP functionality extended to support most SRV_protocol robot control functions -
The latest version of SRV-1 / SVS Blackfin firmware adds most of the SRV_protocol functions to the HTTP interface, enabling more complete robot control via a standard or mobile web browser. Motor control functions are provided for the existing SRV-1q PWM, the new SRV-4WD controller, as well as RC ESC controllers such as Sabertooth and pan/tilt servo interfaces.
Camera resolution and JPEG quality can now be set via HTTP. Also supported are the SRV-NAV gps, a/d, tilt and compass interfaces, generic I2C devices, SRV-1 vision processing functions, and laser pointer controls.
Using the SRV-1 HTTP interface is really simple. To test these, you can point your browser to
http://robot-ip:10001/robot.cgi?____
where ____ represents the SRV_protocol function, e.g.
http://robot-ip:10001/robot.cgi?V
will display the firmware version string
As before,
http://robot-ip:10001/robot.jpg
will capture a new JPEG frame. We have also provided a simple webcam script using this capability.
Surveyor Robot Forum discussion with additional details is found here - http://www.surveyor.com/cgi-bin/yabb2/YaBB.pl?num=1265742063. Example code for a simple webcam interface is provided.
The new firmware has been posted to http://code.google.com/p/surveyor-srv1-firmware/
