Mo' programming, mo' problems- Thank GOD for the IMU

The problem



I think all engineers should play an active part in the programming of any robots they do. I suddenly realize the value of actually and actively sitting down and seeing what your robot can and can't do with the equipment you planned to put on it. A good example might a problem i had with waypoint navigation and the fact that "you have a bearing to head to and an inaccurate compass that updates about once a second" This is not good if your waypoints are close together. If… Continue

Range Video busted for selling illegal video transmitters

You know those excellent video downlink transmitters from Range Video that we recommend? Turns out that some of them are a little too excellent, which is to say that they're illegal (more power and different frequenceis than those allowed by FCC regs without a… Continue

New desktop autopilot simulation software



Mattay does it again: here's an alpha of his new desktop autopilot simulator. The software simulates an autopilot, and you connect it to FlightGear, which simulates the sensors. This allows… Continue

Tutorial: Getting those pesky Atmegas to work the first time

Here's a few quick notes that will help you program your own Arduino-compatible boards for first-time use. This is just for people building their own boards. If you bought ArduPilot or BlimpDuino pre-made, all this has already been done for you, so ignore this.



Here are the necessary steps to… Continue

Programming

Bah...annoyance. Trevor Taylor has been my rope to sanity, i swear! There's nothing like needing just an Int and having to deal with a "list of Ints". which is the right one? you just never know...



Anyways, i'm going to post up what i have done so far. let you guys play with it, incorporate it, comment on it, add it. I think we're decently protected under the creative common license. There are a few things i would LOVE to just make activities, and they REFUSE to compile a such (no… Continue

Cool (and free) waypoint creation software

Mattay has uploaded a very nice waypoint creation application, which uses the Terraserver satellite imagery and a point-and-click interface to create waypoint lists that you can use for your own autopilot. It's everything that PicoGS should have been, and unlike that one, it actually works ;-)

Final (?) BlimpDuino board

I think we're pretty much there on a production-quality BlimpDuino board. It's a beaut, isn't it?

  • Controls two motors and one vectoring servo.
  • Built-in RC compatibility (can read two RC…

The CHAOS of AI

Hey, who out there is coding AI?



My basic assumption is that AI programming today is, at best, a chess program. What I mean is that everything is based off of pre-existing data and a decision tree that handles each situation. In a chess program that means that there is most likely a database of some sort that chooses a move based upon its likely hood of leading to a check mate. Maybe the chess program is capable of assessing which move it should make based upon the chess rating of… Continue

FAQ: What's the difference between a UAV and a RC plane?

I get this question all the time from newcomers, so I'll answer it here as we build a proper FAQ:



Q: What's the difference between a RC plane and a UAV? And why doesn't the AMA allow UAVs on its fields?



A: The generally-agreed distinction is that UAVs have the capacity for autonomous flight and navigation. A RC plane becomes a UAV with the addition of an autopilot.



The AMA doesn't allow UAVs because its insurance doesn't cover them. I actually agree with the… Continue
