Two steps forward – Week 9

So the time for the first outdoor test came and, contrary to my hopes, it was a total failure! Yep, our wheels had too little friction with the slippery wet grass, but it turned out this was the best thing that could happen to me. Me and a friend were discussing what to do in […]

One step back… – Week 8

So after the many test and the poor choice of placement of our sonar, it broke, and the fact that there was a problem with the wiring didn’t help . We discovered this while trying to write a program for the 3d map construction. Rado gave us a seemingly better double sonar, but it was […]

First outside test runs – Week 7

I have ordered a 15 kg/cm^2 servo in case we have the possibility to add the drill. No luck with the software for the 3D mapping. The main event, however, is the firs outdoor test run. Everything went superb, the GPS is very accurate , the shock-absorbers work well and the rover is very fast […]

Software trials – Week 6

So 3D mapping is a very fun feature for a plane, drone or glider because using a data from a GPS and 2D data from a sonar or laser you get a 3D map, but for a rover its a real pain, because the problem becomes […]

A MIRACLE HAS HAPPENED ! – Week 5

Finally new Bluetooth devices have come ! I can’t believe it ! It works and it’s beautiful ! We have ordered sonar for hit avoidance and a backup for 3D mapping. The first model of the drill was mad, I hope it works, but our chassis is small and weight distribution is a real […]

Some progress – Week 4

Half of the week was wasted on attempting to connect with the Bluetooth, so that we could not use the cable every time we wanted to adjust the parameters, but no such luck. The good thing is that we calibrated the GPS and the compass. In theory our Rover is now autonomous. I hope that […]

It’s painful having your wisdom Bluetooth pulled out – Week 3

A whole week was wasted on trying to get the Bluetooth to work. We had a blue-fruit, it was not compatable with our Apm. A few cables came with our Adopter amp, one of them was a 4 pin female cable . So I took another Bluetooth, a 4-pin one, but the cables didn’t quite […]

Setbacks we had in week one and tips.

Most people would think that building the chassis is a piece of cake, and don’t get me wrong, it is, but if you , by mistake, use the wrong screw, getting it out can be a pain ! The servo motor is a very effective way to steer, but be careful before screwing it into […]
