About Me:

A farmer with an interest in technology.


Please tell us a bit about your UAV interest

Interested in ground vehicles and have had a few attempts at building them. This is a link to one of them http://clikire.snappages.com/farmboz-3.htm. Also, might have a go at building a UAV plane or coptor at some stage.

"@Hugues,
I built a custom robot for my farm a few years ago. The farm is all grass and has some slopes but no really rough terrain and after a few attempts I found that a 2 wheels driven by 11 amp wheelchair motors worked very well. FarmBoz…"

"RTK is accurate to within 2cm but very expensive costing approx €10,000.
I was at a farm machinery show last week and there was a guy selling a Differential GPS system, FARMNAVIGATOR from SatconSystem. He claimed it was accurate to within .5 of a…"

"I'm also a farmer working on something similar to yourself. I think the ArduRover is a great starting point for this kind of project. The main problem that I'm having is understanding the ArduRover code. Currently I'm using a second Arduino to…"

"@ Thomas
Found the problem, needed a common ground between APM and Arduino
I've also got a slight problem with the Mission Planner. A lot ot the time it seems to think its an ArduPlane instead of a APMrover. I regularly need to exit MP and restart…"

"Thomas - Thanks for your help
I had considered Sabertooth motor speed controllers but I ended up buying from 4QD in the UK and I've been using them for a couple of years with no problems.
In my current setup I'm using an Arduino and it reads the…"

"Hello All,
I purchased the APM 2.5, uBlox GPS and 3DR Radio Kit and got it up and running with the Mission Planner. I now want to use this with an AGV that has tank steering. The 2 motor speed controllers I'm using have inputs for a PWM signal with…"

I'm considering purchasing a 3DR Radio kit for a ground vehicle, which is the best option in this situation, 433mKz or 915mHz ? My understanding is that the 433mHz is probable the better option.Also, I noticed that the 915mHz kit comes with an air…

"I'm in a different time zone so I'm a bit out of sync with the discussion.
I'm currently using  a HMC6352 compass and had to move it 2 feet away from the motors, even at 8 inches away from the 2 * 11 amp motors it was useless. As I said previously…"

"@Thomas
Going for APM1 seems feels like a bit of a backward step and I don't think there's much of a price difference. However, the robot is only intended for a top speed of about 5 miles/hr so that probable leaves the gyro and acclerometer…"

"I'm still undecided about buying an APM2 for my robot. My main concern is that a lot of the sensors and code seem to be redundant for the purpose of using it in a ground vehicle but maybe someone could correct me if I'm wrong about this. Also, I…"

"I'm checking out the Raspberry Pi. It is low cost with minimal power consumption, low weight and speedy boot up. Considering setting it up as a wireless webserver using a wireless mobile dongle or maybe using WiFi. Then it could control the robot…"

"Is anybody here familar with the APMrover2 code? I was looking through the code hoping to find where the speed and steering values are outputed in the hope that I might be able to adjust them for tank steering, but had no luck finding them."
