The ardupilot development team is proud to announce the release of version 2.47 of APM:Rover. This is a minor bug fix release. The most important change in this release is the fixing of the skid steering support but there have been a number of fixes in other areas as well.
Full changes list for this release:
- add support for controlling safety switch on Pixhawk from ground station
- prevent reports of failed AHRS during initialisation
- fixed skid steering that was broken in the last release
- report gyro unhealthy if gyro calibration failed
- fixed dual sonar support in CLI sonar test
- fixed Nuttx crash on Pixhawk with bad I2C cables
- added GPS_SBAS_MODE parameter - turns on/off satellite based augemtation system for GPS
- added GPS_MIN_ELEV parameter - specifiy the elevation mask for GPS satellites
- added RELAY_DEFAULT parameter to control default of relay on startup
- fixed bug in FRAM storage on Pixhawk that could cause parameters changes not to be saved
- better handling of compass errors in the EKF (Extended Kalman Filter)
- improved support for linux based autopilots
- added support for PulsedLight LIDAR as a range finder
Many thanks to everyone who contributed to this release, especially
Tom Coyle and Linus Penzlien for their excellent testing and feedback.
P.S. Hi all - I am helping Tridge with Rover development and this is my first release announcement.
Happy driving!

Hi everyone. I too am trying to finish up some work but from 15 December there is going to be MAD amounts of APMing :-) I've got so many things to try and get up and running - we are going to have a great time!
sorry guys, I was a little absent and look forward to future adventures with the rover and you!

Yes, it is quite impressive and the 3 degree beamwidth is nice. It could tell the difference in distance of the empty shelves on our TV stand and the stand itself from 3 meters away. It's quite the nice sensor at a very affordable cost. I thought about giving it a try with a robotics project over the winter. I don't have any 3DR gear at the moment as I just don't have the time to tune it all with 4 little kids but I'm saving this sensor for when I have a little more time in the future. Might as well sell of what I had when I could get something for it. When I get back into things, the hardware will be even better. Lucky for me, I get to play with this stuff at work so I still get my fix!
@healthyfatboy,
I just received my LIDAR-Lite also and recently tested it on an Arduino Duemilanove and it works most impressively. Next will be to incorporate it on a rover, however the beam is so narrow that it will require a servo to sweep the module across the path of the rover.

Hi Grant,
Welcome aboard the ArduRover2 Team.
A most impressive list of fixes and improvements!

I just got my LIDARLite in yesterday from PulsedLight and did a quick test of it on the Arduino and have to say it's quite amazing! It'll be perfect for using on a rover and it's great there is support for it in the code now. Congratulations!
Thanks Grant!
