Hello All,I'm currently trying to develop an autonomous rover that is capable of running in a straight line following a perimeter without the use of a perimeter wire (using a preprogrammed route). The chassis I am wanting to use is hydrostatic driven ZTR using servos to control the pump valves that adjust the speed and direction of each drive tire. It also needs to be able to run a line pattern over the entire surface of the area (run a straight line from the south perimeter to the north perimeter, do a 180 and run another straight line parallel to the first back to the south perimeter). I would like to use the pixhawk or similar controller such as the HKPilot32 and the Piksi RTK GPS paired with a Ublox Neo-m8n. Is this something that can be exicuted without wobble in the lines using a Piksi RTK GPS or will I need other guidance modules? I'm not sure what I need or if the Pixhawk is even capable of doing what I want. Any help would be greatThanks

Ok, so should I ditch the Ublox GPS and go with 2 Pikis RTK GPS to get the best signal lock I can? Would creating a base station help at all? Is there a way to incorporate the compass on the Ublox GPS to help keep the rover on a straight path? Sorry for all the questions, I just don't want to drop $1,000 + on equipment just to find out it won't do what I'm wanting.
You have to remember that your straight line is limited buy the GPS signal on any given day, including your locations and ground clutter.
Gps does not work as well on the ground as it does in the air.
You also have manometer that will help with guidance but again, depending on geographic location and what is under the ground will determine the accuracy of your straight line. .
One last thing, , there is no evade and avoid system at this time that is a simple plug and play that will work with the pixhawk or its clones.
Now you will have to get into programing, and writing code and make your own system.
The mechanical part is easy,, it's samplings the surroundings and having a computer control the pixhawk around obstacles...
It is being done but not so much on the hobby side of things..
Join NASA and or the Military they have more money for R&D. ... LOL..

Thanks again.
