1  Using Arduino / Networking, Protocols, and Devices / Re: WifiFly RN171 Receive data from web browser on: April 08, 2014, 02:34:54 pm
I don't want to run this on Arduino. I am running this on a Xilinx Spartan 6 running a microblaze. I came to this forum because i know alot person use this in the Arduino community. But the code set I found for arduino was not easily portable. This set of codes are.

Also the I am running this on top an RTOS and the. I'll just create a wrapper function for the serial calls they have. And replace all the memory allocation with RTOS specific memory allocation.

I found what I need so this post could be closed.

Thanks

Ok I think I found a code set that was better written. This is much more portable than the one presented below. All i need to do is write a wrapper function for my serial calls and timer.

Hello pylon,

The module datasheet is attached. The code that I found is attached.
Also it key to note that I am not using an Arduino I am try to use code from the libraries provided by the Arduino to write my own driver code. But I am little confused how they setup the web server. I can't find where there sending the specific commands to the RN171 to set it up as a web server.

Also the other thing I want to do is resubmit data from the web client (browser) using a form.

Hello All,

I am trying to setup the RN171 to receive data from a web client. That is I want to create a web server on the RN171. So that I can load the HTML code from a browser and send data via the browser to the WiFi module.

I can't figure out how to do this. Has anyone done this. I have read through the manual but doesn't offer any help pertaining to this.
5  Products / Arduino Yún / Using realtime operating system with the Yun on: April 04, 2014, 02:11:55 pm
Hello All,

Been a while since I posted on this forum.

I am interesting in using the Yun but I need to know if there any real time operating system support for it. I want to run the RTOS on the Atheros AR9331.

Any help is much appreciated.

Thanks

Yup, I will be removing the mega from the board. That was the plan.

Hey,

Quick question when uploading a program to the Ardunio Uno or any Ardunio the data is routed through the RX/TX lines to the MCU. The reason I am asking I am trying to hook my Atmega168 to my Uno board so I can program it. The Atmega 168 already has a bootloader on it.

If the object is known, you can use readily available AR libraries to establish its

Could you point me in the direction to where I can find these libraries, for android cable device.

The object will be unknown when it comes to 2D space for now because it will always lie on a surface "Y" (height) distance away from the arm. Once I get that working I will start to work in 3D space. For now the object can only move around in an X and Z plane that is left and right of the camera and up and down in depth view of the camera.

I am planning to use my android phone to do the camera tracking, for now it won't really be tracking anything it just going to find the object and try to figure out where it is in real space. If I can't do this I might have to mount the camera on the arm as you said.

Well the arm is just basically used to pick up things. But first got to get the arm to go to right place before I can get it to pick up things.

In terms of writing a arm solution library. I done work in my university with writing libraries for vector analysis using IR sensors.

In terms of the arm solution library there will only be one unknown as I see it that is the object which is not moving.  The camera and the arm will always be set into know position for X,Y,Z planes. The camera will not be mounted on the arm though.

I then need to use sensor to measure where the object is relative to sensor (if I can use the camera it measure the distance that would be good but I don't think I can do that would good enough accuracy). Once I get that data since the arm and sensor are in a know position relatively to each other I can then figure out the vector between the object and the arm. Doing this will allow to get the arm to traverse the vector that i created in 3D space. I could do 2D space and then for the 3rd dimension which is depth in my case calculate another vector for this and this should allow me to move the arm to correct location.

The arm will have sensor on it which will give me angles relative to it's start position which is always know. Since I know the length of each section of the arm and the angles I can calculate where the arm should go.

The hard part I really see if getting the sensor to measure the object since I will need to aim the sensor directly at the object which is relative to camera that will be looking at the object. If I can get the sensor data good. The vector won't be hard to calculate that first year university mechanics. smiley

I will work out the math tomorrow. Once I get my model correct I'll start to build

I am also thinking of using the android to do depth measurement that is distance in both X and Y plane. So I could figure out how far the object is. Any thought on that I have no idea where to start on this one.

Hey All,

So I'm getting bored since University is out for the summer. I want to build a robotic arm that can pick up objects using the android as a camera. Has anyone done anything like this before. If should any help would be much appreciated.

I know about a year back I came across some projects online where person were able to do optical tracking using the android. I trying to find this desperately but I can't does anyone know where I can find this.

Then I would need to work out the vector analysis for the arm relative object so the arm can traverse the imaginary vector in real life, the general idea is after I work out the vectors I will make the tip of the arm follow the vector and if it follows the vector it will aways come in contact with the object. At least that how I see it. Unless I can mount the camera in a position where I can get it to see the robotic arm and the object and track them together.
 
All ideas are welcome. My first way of doing it might be very computational, better idea are very much welcome.

No i will store it. But that not hard I have done multiple projects with arduino and android. I just have not worked with may microphone and thus I don't know any good brands and so on.

I know how to build the circuitry I already have a rough design.

I think you miss understand how the system works. The Ardunio must never stop counting it must count all the time. I am recroding count per hit or counts per blow so I will know how far the pile has been driven into the ground.

The only way to measure the number of feet you sink is to have someone look at the pile while it sinking, the pile has marking on it the marking are made before the pile is raised by the crane and these marking arn't made in any special way someone would either just draw a mark on it every 6 feet or so. Every time the piles sink 6 feet he would press a button on the device which would record it. So I would get hit per blow as a unit. I have owned one of these before it's just that they are very expensive to buy they cost 7000us or so and the type of piles we drive into the ground at our company doesn't require those advance one. Usually the pile we drive are driven in relativity hard mud so the sound is very unique. Most these meter compensate for oil rig pile driving.
I don't need one of those.

So yes I would need someone to press a button because there no one way to measure the amount of feet the pile has sunk. And i cannot put anything on the pile it will be destroyed buy the impact hammer the amount of force the hammer generates make the ground about 30feet away feel like a earthquake trimmer.

I can't turn off the device because the hammer doesn't stop until the pile is driven all the way into the ground. I need it to keep recording until the entire pile is driven into the ground every few minutes the pile would have sunk to 6 feet the operators just press a button.

I worried that when the operator taps the device to record the number of feet the pile has sunk it will create an extra reading on the pizeo meter. Since the operator hold the device every x number feet the pile sink he press a button that records it on the device.
So basically if he does that and the piezo meter think it actually a hit it will record false data.

I'll look into the piezo element thanks by the way
