After months of beta testing Rover-3.5.0 has been released as the official/stable version and will be available for download through ground stations including the Mission Planner and QGC within the next few hours.

The changes are listed in the ReleaseNotes and also copied below.

    a) Follow mode (allows following another vehicle if connected via telemetry)
    b) Simple mode (pilot controls direction regardless of vehicle’s heading)
    c) Loiter can be configured to always drive towards target (i.e. does not reverse) (see LOIT_TYPE parameter)
    d) Guided, RTL, SmartRTL will reverse towards target if DO_SET_REVERSE command received (via telemetry or as mission command)
    e) Boats hold position after reaching target in Auto and Guided (also see MIS_DONE_BEHAVE)
    f) SmartRTL default num points increased to 300
  6. Auxiliary Switches expanded to many channels (see RCx_OPTION parameters)
  7. External position estimates accepted from ROS and Vicon systems
  8. MAVLink message interval support (allows precise control of mavlink message update rates)
  9. Safety Features:
    a) RC and GCS failsafe timeout shortened
    b) EKF failsafe added and checked before entering autonomous modes
    c) Object avoidance enabled in autonomous modes (Auto, Guided, RTL)
    d) Safety switch ability to arm/disarm vehicle now configurable (see BRD_SAFETYOPTION parameter)
  10. Bug fixes and small enhancements:
    a) Object avoidance fix to include all sectors from proximity sensor (aka 360 lidar)
    b) Onboard OSD support (for ChibiOS-only boards)
    c) Gripper support
    d) Sprayer support
    e) Wheel encoder offset fix
    f) Avoid potential divide-by-zero when waypoints are almost in a straight line
    g) Cruise speed/throttle learning always runs for 2 seconds (saves user from having to lower switch)

There is still at least one known issue (DShot support) that we will resolve in a follow up “point” release. Some wiki updates are also required which we should get to in the coming weeks.

If you have any issues with this release please post below or create a new topic in this Rover-3.5 category

Thanks to those in this forum that helped out with beta testing, it was very much appreciated!

By the way, if anyone has a video of their rover or boat I’m looking for a better video to put at the top of the announcement blog post. No pressure of course!

I will give it a test Randy, thank you.

Do you think this will resolve my boat wobble problem?

(David Boulanger) #5

I might have one for you in 12 hours or so.

(David Boulanger) #6

I did not get anything worth editing worthy of this community. Sorry.

This release doesn’t include any changes that will help with the wobbles I’m afraid. That will come with Rover-3.6. Until then though i have an idea which I’ll post in the other topic.

(John Easton) #8

So should I do the update or stick to the old version?

Hi John and Randy

Would a mode or feature like Boat mode for Copter be relevant for Rover? Maybe helping with problems of powering and arming boats on water. I get gyro warnings a bit when arming on water. I like doing it as it sets home in a good spot for retrieval.

The parameter for setting up boat mode. Shows up on rovers full parameter list in docs. You could try setting it. Se if it works.

(rmackay9) #11

Hi @John_Easton,

it’s up to you whether to upgrade or not. i think it will do no harm and should be an easy upgrade (please tell me if it’s not).

(rmackay9) #12


Copter’s “boat mode” is available in Rover as well. It’s not really a “mode” (like Loiter or Acro), it’s more about how to ensure the gyro calibration completes. Maybe we need to do more to make it work reliably? It’s a good point and you’re the first person to bring it up I think.

Randy and hdtechk

I will give “boat mode” a try on the weekend, I wasn’t aware of it in rover. The thought came to me after reading some of John’s thread with his trimaran.

(Kurt shaw) #14

More important though is home is set when you arm unless you set up always armed
