I just stopped by and it's crazy to see everyone who is still around. Feels like it's been forever.

I currently don't have time/money to put together a new mech project, but if somebody wants to...

I'm hoping to bring my mech to this one. I've got significantly more resources at my disposal now thanks to my university; most importantly a machine shop and a couple comp-sci guys who volunteered...

I won't be able to get my mech up and running by then unfortunately. I keep getting sidetracked trying to optimize my gait engine and I never got around to milling the other three Tibia's I need. Ah...

The analog discovery is pretty nice. Does what it's supposed to; super user friendly documentation. I got it and a decently sized kit of components for all of $150 because my college uses it for...

I think it could be interesting to remove the 1 hit/s cap on the panels and instead imposing a rate of fire limit on all mechs. My thinking being that getting in close and unloading in bursts would...

Experimenting with aluminum brackets:

5952

This was my first attempt, I used some leftover 0.050" T6. Bends were done with a break I made out of angle iron. The main issue looks like it's going...

I second tician's response.

My panels just have the velostat stuck down with double sided tape on the edges and rest on the traces. The sensitivity worked out just fine, there is plenty of difference between resting and a bb...

What panels will you be distributing? I stopped working on mine because I liked tician's panels more and I was getting ready to see about getting my hands on some.

Oops I meant to take that out :). Definitely my brother's fault. Yeah, pretty smooth :).

Sure! Github. Good luck understanding that :p. It is the result of two incredibly lazy programmers at 2:00 in the morning. It's going to be reorganized, cleaned up and commented soonish (probably).
...

Well, took a little longer than expected, but with some help from my brother it's walking. Using an Arbotix-M for now. Beaglebone Black was looking like it was more work than I wanted to do at the...

These are looking great! Do you expect to have them ready for March or should I finalize my panels for competitors at the WV event?

I'm in if Chicago isn't happening this year (if it is then maybe). I'll be able to show up on Friday to help out as well.

My panels will likely be ready by then, I can send some to you, sthmck, if you would like to review them in lieu of official approval from Andrew. I've just been swamped with school/work, but I'll be...

There are mounting holes for an AX-12 on the top of the PhantomX quad, and like Jwatte said you don't need two Arbotix's. I'd recommend just mounting an AX-12 to top, and purchasing a couple brackets...

From the AnalogInOutSerial example:

The circuit:
* potentiometer connected to analog pin 0.
Center pin of the potentiometer goes to the analog pin.
side pins of the potentiometer go to...

Ah, I did not mean to say that the modification of dxl_hal.c was causing the issue, simply that if one were to make the modifications required to use the USB2AX (which I assumed was what arman had...

The linked thread is mine, and discusses modifying dxl_hal.c so it works with the USB2AX, what am I missing?

True, however I do believe that there are other modifications in Xevel's version (such as changing the serial port name to ttyACM instead of ttyUSB or whatever) that would need to be left out if you...

Also, you should not change dxl_hal.c if you are using the USB2Dynamixel. You only need to modify that if you are using Xevel's USB2AX.

Updated to include Onyx Fire II board. I'll add a bit about R-Team's setup soon. Though, if you wanted to write up a quick guide about your setup I'm sure you'd do a better job of it than I could....

How is the mech warfare committee coming along? I think it would be very beneficial to get that going as soon as possible. Having some leadership to coordinate community efforts on MW related...

Looks very thorough, nice job!

One thing you may wish to clarify: On page 4 (in the table) minimum input voltage is specified as 7V, but on page 6 (paragraph 1) it says:

Since I intend to power...

The retaining screw did the trick, thanks!

Progress:

Everything went together fairly smoothly so far! Just one thing i'm having trouble with: I can't figure out how to get the horn onto my MX-28 :p, it's really, really difficult to...

I'd go with interpolation, it seems to be the preferred method. The Bioloid library has interpolation functions that are really easy to use, so you probably wouldn't have to write too much code.

You may have mentioned this already, but is it possible to power the guns with a separate power source (2s lipo) instead of the dynamixel bus?

If so, I'll get one too!

It's mentioned in the Arbotix manual under "I2C and Serial Headers", the getting setup page under "Upload Pypose Sketch", and the Arbotix hardware overview under "FTDI Serial Port / Programming...

I believe they are micro metal gearmotors from Pololu.

Edit: Also says so in the agitator description on shapeways.

I did a quick latency test with the following system:
FatShark "CCD Killer" 600 TVL CMOS camera
FatShark 250mW TX
ImmersionRC Uno5800v2 RX
Rubber Duck Antennas (Circularly polarized antennas...

Those are the frequencies that Tybs said he will be using. So probably a good choice. (See here, and here)

I just did a quick test of my camera system, (details here) and I'm really happy with it. The only thing that's missing is the circularly polarized antennas, which have yet to arrive.

The video is...

I heard that someone else seemed to remember claims that the servos tend to overheat if you use the speed control instead of interpolation (see here). I haven't actually tried it, just something I...

Two byte registers will have a low and a high byte, indicated by _L and _H respectively in the preprocessor directives (in the bioloid library) or by (L) and (H) in the ax-12 manual. You should see...

First of all, you should use code tags when posting code so that we can read it.

void loop() //Main program - infinite loop
{
LineFinder = digitalRead (52); // voltage measurement of sensor...

Very impressive!

The only thing I might be worried about is the angle of the hopper. If you have to aim too high (at giger for example) gravity will no longer be your friend ;).

Looking forward...

For the pins, a little google powers or just looking at a breakout board should get you what you need:
5332
Just match GRN on the breakout to GRN on the arbotix. Keep in mind that the breakout's tx...

That TX/RX kit uses a different channel group than the one Tybs said he would use at the event. I don't know if that will be a problem but at the very least you won't be able to use any RX that Tybs...

I might wait until the guide is a little more complete and refined. It's no fun to update and edit things in two separate locations :).


I believe you can attach files to a post using the paper...
