"I'm impressed that you are down to around 1.5M, and I think what you are doing is great.
The gyro heading should be to within .5 of a degree? Are you happy that the GPS speed and distance derivation is accurate enough? I wondered about an…"

Derek commented on Thomas J Coyle III's group ArduRover User Group"Thanks for the discussion links and input. I know that if we setup a high quality GPS station at the start point and have good enough software to calibrate the Bot GPS offset, we can be accurate to less than 4 inches over a course. I have seen it…"
Derek replied to heliboy's discussion ArduRover 6x6 works ! in the group ArduRover User Group"Congratulations Vijay. Very Impressive. Best of luck."
Derek commented on Thomas J Coyle III's group ArduRover User Group"A cheaper option may be set out a marked number of waypoints on your own test course and beg,borrow or steal an accurate D-GPS to mark your start and waypoints. Whatever your own setup for GPS, heading and hardware you can then test and tweak…"
Derek replied to Andrew Tridgell's discussion How should we handle reverse in ArduRover? in the group ArduRover User Group"Hi,
Just some thoughts on reversing.
Driving Remotely by Camera - you would need to pan 180 to follow the reverse path and then steer the wheels in reverse mode.
Loss of GPS - on trails, canyons, in wooded country makes the use of the heading and…"
Derek replied to Derek's discussion Waypoints and Gridding"Thanks Michael. I am trying to mechanize my geophysical search equipment. It has a lane width of between 1 and 3 yards, depending on setup. To get 100% coverage of a field I need to be able to specify the grid size and waypoints. An analogy is…"

The Ardurover has a capability of being in the 'field' much longer than flight equivalent missions. What are the limits of waypoint numbers and grid size available? If there are limitations, can they be extended and is it a complicated fix?Thanks See More
Derek replied to Carlos's discussion Gps guidance in the group ArduRover User Group"The software on this site has taken thousands of hours to write. The investment in hardware and firmware has also been colossal and I am truly amazed at the effort and dedication that has, and is going into these projects.
Software mods have to be…"
Derek replied to Carlos's discussion Gps guidance in the group ArduRover User Group"I suspect that we are all going to have the same problem, so please let's keep in touch about this. My initial thoughts are that the Mission Planning software will require code that automatically pre-loads the waypoints dependent on parameters…"
Derek replied to Carlos's discussion Gps guidance in the group ArduRover User Group"Hello Thomas/Carlos,
We need as much accuracy as we can squeeze out from a system. preferably less than 12 inches. If the need is for a more accurate GPS then it will have to be paid for. The LEA-6 spec is quite impressive. GPS accuracy may not be…"
Derek replied to Carlos's discussion Gps guidance in the group ArduRover User Group"Hi Carlos, I'm new and was about to ask similar questions. I'm interested in amateur geophysical survey which needs GPS guidance to have lane discipline as required in harvesting together with constant speed over ground.
This needs a…"
