Hi all
I thought I should give a shout out to say :
I. put some ideas, tasks, example code on the wiki - see the remote team page that links from this page http://wiki.xinchejian.com/wiki/Swarm_robots/Soccer
2. As you all know I am leaving the country, so this week is your last chance to get me face to face, after that it is web only!
3. Please also keep a close eye on what ALL the other teams are doing as we need to work closely with them to get the remote control parts working with their parts.
We really need to take care to know which team is doing what bit as a LOT of what the Remote team is doing has to be integrated into the work of **ALL** the other teams!
This even includes the design team - for example if they COVER the field with some material as seems to be in the proposal, then can we transmit IR through this material?
4. It seems like the proposal for the central controller/communications is going ahead - again see the wiki. Also Edward knows more detail on this.
5. I can probably make it to one or maybe two more sessions, but it is really up to ALL OF YOU ON THE REMOTE TEAM to organise (including when/if you need me this week) and deliver!

Thanks Spencer,
yes I/we will update the Wiki as soon as we find the time.
Wednesday and Thursday (if you have time please join on one or both days) we need to nail down how to merge the teams more or less. As you mentioned, there is a demand to share all the information with each team.

I got one and I am also in the XCJ group...i guess ;-)
However, I never got the system running smoothly, so I abandoned it ;-)
I will install it again on my machine if we're going to use it more often.

Please do! Ask for help if you need. It's a bit painful at the beginning but much better for teamwork.
I'd really like if we could put the insectbot code (for example) and maintain it there... I had to clean up the code from a copy on a USB key in Beijing and it was not fun ;-).
Pro-tip Lutz: in Arduino IDE, CTRL-A, CTRL-T ;-)

Ok, will try this these days.
Haha, got it! Auto-format is not always aprecciated when I write code since it's confusing me when the machine is doing something without my permission ;-)
But you are right, some improvements could be done in my code design.

Hi guys,
I've manged to do a very simple IR seeker tonight, doesn't work too great yet, but good enough to reveal some problems:
1. The IR receiver modules are very good at picking up the IR signal, all 4 receiver facing all directions are all picking up the signal, I need to warp a paper over the small remote control to allow only one receiver to receive it at about 30cm.
2. Everything reflects IR, ricky's face reflects enough IR to allow the receiver to pick up the signal at a distance of 3~4meters.
Let's discuss the details tomorrow.
Regards
Edward

Well, i was not that successful last night because I do not have a device which is measuring frequencies. The setup with an IR receiver and an Arduino did work for my TV remote but not for the selfmade beacon. Probably the voltage have to be stabilized to 9V in my setup but I could not power it with others than an used 9V battery.
I got the breadboard in my bag for tonight, lets see if we can improve your setup to take the next step.

Sure, let's hack it out tonight. I need a good beacon with a good protocol to allow it to interpret the difference between different beacons.
A power supply what you need it is...

I have an idea about how to counter the reflection, but not sure if we have enough bandwidth left for that.
We cannot measure the signal strength from the receiver side as the integrated receiver amplify the IR signal to digital signal. However, we do have control over the intensity of light we are sending out from the beacon.
So what we can do is sending increasingly stronger beacon signal (3~5 intensity levels) and there should be one level which not all sensors can pick up the signal, so the robot can make use of this info to find the direction of beacon. And we also can figure out the rough distance between the beacon and the robot.
The downside is we will have to transfer multiple times of the same beacon signal which takes up valuable bandwidth.

Edward

if you increase the speed the intensity will drop, hence more bandwidth

We can't change the carrier frequency which is 38k... we can increase baudrate, which essentially decrease number of carrier wave per bit, which increase the error rate, which is as good as dropping the intensity maybe, i think you are right, i'll certainly try different baudrate tonight!

I like your idea.
I'm not sure about your current circuit, but your first transmitter I saw was driving the LED very very hard, probably get 10-15 plus meters range, so there would certainly be room to reduce the strength!
In addition to your idea suggest it is most likely that you can reduce or even remove the extra transmit signals if the ENTIRE transmit - receive system is tested and calibrated in:
- the actual field, with the actual paint
- and especially any cover OVER the field as seems to be shown on the proposal (ie more chance of reflections)
- and once again, against the ACTUAL shopping centre lighting conditions
I actually have a test PCB for changing the base & collector resistors via jumpers - I made it because I thought that breadboards might (do?) interfere with the relatively high current pulses (1-4+A) that can be sent!
Attached is my circuit and a link to the forum where I discussing testing. I can drop of this test board if you need it.

btw - in emails sent after the one below - changing the BAUD rate might help, but it is MUCH easier and more precise to control the the transmitter LED current!
I like your idea.
I'm not sure about your current circuit, but your first transmitter I saw was driving the LED very very hard, probably get 10-15 plus meters range, so there would certainly be room to reduce the strength!
In addition to your idea suggest it is most likely that you can reduce or even remove the extra transmit signals if the ENTIRE transmit - receive system is tested and calibrated in:
- the actual field, with the actual paint
- and especially any cover OVER the field as seems to be shown on the proposal (ie more chance of reflections)
- and once again, against the ACTUAL shopping centre lighting conditions

I have an idea about how to counter the reflection, but not sure if we have enough bandwidth left for that.
We cannot measure the signal strength from the receiver side as the integrated receiver amplify the IR signal to digital signal. However, we do have control over the intensity of light we are sending out from the beacon.
So what we can do is sending increasingly stronger beacon signal (3~5 intensity levels) and there should be one level which not all sensors can pick up the signal, so the robot can make use of this info to find the direction of beacon. And we also can figure out the rough distance between the beacon and the robot.
The downside is we will have to transfer multiple times of the same beacon signal which takes up valuable bandwidth.

Sure, let's hack it out tonight. I need a good beacon with a good protocol to allow it to interpret the difference between different beacons.
A power supply what you need it is...

Hi guys,
I've manged to do a very simple IR seeker tonight, doesn't work too great yet, but good enough to reveal some problems:
1. The IR receiver modules are very good at picking up the IR signal, all 4 receiver facing all directions are all picking up the signal, I need to warp a paper over the small remote control to allow only one receiver to receive it at about 30cm.
2. Everything reflects IR, ricky's face reflects enough IR to allow the receiver to pick up the signal at a distance of 3~4meters.
Let's discuss the details tomorrow.
RegardsEdward

I'd really like if we could put the insectbot code (for example) and maintain it there... I had to clean up the code from a copy on a USB key in Beijing and it was not fun ;-).

I didn't use my own LED signal generator this time, i used one small IR remote control i got from lutz instead, didn't get a chance to build one myself, which we may need to make tonight.
I totally agree we should have a trip down to the mall and do some on site measurement.
Nice article you've written on the IR circuit, really detailed documentation. The circuit you saw me used the other day was actually driven by a Mosfet 2n7000, way more powerful than any transistor / darlington, basically it is hard switch on / off with little resistance, currently is only controlled by the current limiting resistor. But I need to switch back to a transistor for a better linear power control or else i'll have to design a feedback circuit.

The IRToy project has now changed to a " 100mA constant current
IR transmitter with improved range". Their circuit is here:
http://dangerousprototypes.com/docs/USB_IR_Toy_v2#Infrared_transmitter
Swarm robots may only need 10mA if the LEDs are similar for the smaller range and less reflections!
