Wireless/Zigbee for PIC Micros

Back in 2009, my professional work involved leading the firmware project of a low power wireless network of sensors collecting temperature and humidity data. Wireless gateways accumulated the information and sent to a data center over the internet. During that project, I fancied my own Zigbee network for my robots and setting up a network of home monitoring sensors. I eventually bought some Microchip MRF24J40MA modules (which is a completely different platform than my professional work).

Juice Box Robot Plan, Needs review

***UPDATE MARCH 11: After reading the comments here I have made a couple of changes to my plans. I have replaced the PICAXE 18 with the PICAXE 28 and appropriate board. I have switched to 3 AAA cells as a power source and I have changed to servos to power the "arms". When I wrote the original post used the word "arms" as a placeholder, but while I always intended to have actuation it was never actually going to be a set of arms.

Can I stream a wireless camera through wireless usb?

I was thinking of wireless cameras since the beginning of time and I've finally come to the decision of buying one. For me, there are two options: a camera that transmits to an rca/composite 2.4Ghz receiver which in turn is connected to a rca/composite to usb converter, or a camera that transmits to a 2.4Ghz USB receiver. In both cases, however, it seems like the stream must first be recorded by some program and that doesn't really fit useful applications for robotics. I want to process the data live with OpenCV and then relay information to the robot.

I have a question, how can I control 10 or more arduinos wirelessly?

I have an idea, but in order to make it possible I need to find a cheap and easy way to control more than ten arduinos wirelessly. Please help :).

Can Arduino RBBB programmed wirelesly by wixel?

I have an arduino rbbb for my robot and i want to upload sketches wirelesly via wixel and wixel shield.. I am asking because at the description of wixel-shield says that it will not work with arduino Leonardo.. and i am wondering if that also happens with rbbb. It's not an official arduino so that's maybe the reason why it is not mentioned if they are not compatible. Any suggestions would be very helpfull.. thank you!

 

Where should I start with wireless robot-to-computer data transmission?

I'm working on a project where my bot collects some information while traversing a grid. I want to send the findings back to my computer wirelessly as the robot is moving. The range is not far (2-5 metres) and I am on a budget (Up to $20 but the lower the better).

The data I need to relay needs only be three sets of three single digit numbers. I could even condense it to be three 3 digit numbers or one 9 digit number I suppose.

[SOLVED] toggle ON/OFF remote LEDs

I can't believe I'm just about to ask this... but it has been a nasty weekend and despite all I've managed some progress. So yeah, now a feel a little silly at throwing the towel at some LED toggling.

So, I have a prototyped remote (TX) that send X, Y info from a joystick plus four buttons. The information is transmitted as an array in the shape of:

[XXX, YYY, A, B, C, D]

feasibility of DIY wireless headphone kit

So, I was searching the market for what my wireless headphone options were and got quite disappointed.

As it seems, wireless used is either IR, RF (on the FM/UHF band) and Bluetooth (also 2.4Ghz seemingly working in the router's norm).

IR ... needs line of sight, small range...
RF... prone to interferences
Bluetooth... small range
2.4GHz... some reviews said they interfered with the home wireless routers

 

how to send sensor values wirelessly

i know how to send messages to another arduino but im not sure how to send sensor values here is code to transmit the word hello 

If you could show me an example code it would be great.

// transmitter.pde

// Simple example of how to use VirtualWire to transmit messages

// Implements a simplex (one-way) transmitter with an TX-C1 module

cheap wireless shields for arduino

I was looking for wireless shields for my arduino and stumbled across      this http://www.kickstarter.com/projects/1608192864/open-source-wireless-inventors-shield-for-arduino 

its a wireless shield for arduino that has 177meters range and is easy to program check out the link above for more info

what is the best way to communicate wirelessly from one arduino to another

I have 2 arduino megas and would like to send the potentiometer values of one arduino to control servos conected to the other arduino and I have never used any wireless things with arduino before I have a 433mhz transmitter and a reciever but havent been able to find any useful code for it and was wondering what other wireless devices i could use for sending potentiometer values wirelessly to another arduino easily . Any sugestions and example code and where to buy it would be greatly apreciated thank you

Wireless surveilance system..

Hi, all, this is a bit of a random night post, but, i need your help...i need a cheap way to make a surveilance system.. 

I have a CCTV camera module that looks like that, and no, it's not wireless, doesn't have a receiver. It only has Audio/Video cables and a power cable. Is there a cheap way to make this work using bluetooth? I only need to spy from 5 meters away. Btw, i want to be able to receive the video from my laptop. 

Transmitting 2 HD-SDI video streams over wireless

Hello all, I've got a problem I've been scratching my head on for a couple days and figured I see if anyone here can help. 

Let me set the scene. 

You have two high definition camera's onboard a robot that have HD-SDI (or HDMI) outputs. 

You need to transmit these camera feeds to a laptop wirelessly to view. 

You have a small "mini-PC" computer on the robot (similar to one of these http://www.stealth.com/littlepc.htm).

Wireless webcam?

Hi,

Does anyone know of a cheap wireless webcam? I found one from maplin, but the reviews aren't brilliant. I wouldn't want to spend any more than £20 ideally!

How to build BeagleBoard based WiFi robot

Some time ago I have announced my remotely (over the Internet) controlled robot. However, there were not too much documentation and details. So with this post I would like to announce the availability of more detailed project documentation and make brief overview of some interesting aspects of the project. The whole available documentation could be found on the project Wiki.

Which bluetooth?

So I am planning on going wireless with my robots and I was wondering which one I should buy. I was looking at sparkfun and I found many blutooth. What qualities should I look for are some better than others? Also I intend to use the bluetooth for only about 100-150 ft and I am mostly going to use it for the arduino. This is what I found so far:
