Help Deciding, and other dillemas

Haldo everybody,

I was dragged into robotics by my brother, Red Fox Dude. Anyway, I want to get a RoboNova with Matt Bauer's grippers, but I've got a problem. How do I get the robot to be controlled by RC or BlueTooth? Or should I just go with a KHR-2?

EDITTO: Okay, I just noticed the topic about RC controlling. Umm... Yeah. By the way, it's pronounced (ed-DEE-toe)

EDITTO V.2: Oh, and where can I get gyros for a RoboNova?

Hi,

As you've noticed there is lots of stuff on the forum here such as threads for :

RC
http://robosavvy.com/modules.php?name=Forums&file=viewtopic&t=206
Bluetooth
http://robosavvy.com/modules.php?name=Forums&file=viewtopic&t=125

These are just examples I know there are many threads with lots of info. I have run RC control and now run Bluetooth with a PDA and .net app as the control for it.

You can definately get both to work and the forum will tell you how.

Hope this helps

Pev

I was looking around, and it looks like you can't have gyros and an RC control... Darn it. Is there any other way to set up a controller that doesn't take up a port, or something? And again, where can I buy gyros?
:O

Hi,

As I pointed out near the end of my R/C message ... there are enough A/D ports for R/C control and one gyro ...

I don't see a need for a side-2-side gyro ... so I'll save those two ports for the R/C link ...

I use a bluegiga bluetooth module in my robot and a cell phone for my controller. All the tools to write java code for the cell phone are free.

java tools:
http://www.netbeans.org/downloads/
get netbeans IDE, Mobility pack and Profiler
make sure to get J2SE 1.4.2

You need to have a cell phone capabile of CDLC 1.1 with bluetooth
I use a moto Razr V3X so I also use the motorola SDK
http://developer.motorola.com/?path=1.2.6.25.768

I have also a three axis accelerometer and 2 gyros.
The accelerometer I purchased from http://www.sparkfun.com
The gyros are the pg-03 gws gyros.

The phone gives me robot stats such as gyro state (which axis has the gyro enabled), accelerometer readings, command status such as in motion and move complete. The phone displays graphics to remind me what page I'm on, fighting, acrobatics, salute etc...

My phone java code I'd be happy to share. It will likely need to be modiifed for other phones. PM me and I'll be happy to send it along.

I find a phone to be an ideal controller because I always have it with me (I don't have to look for it or remember to bring it with my robot), I already had one (so it didn't cost much), it can do much more then an r/c transmitter or play station remote (transmits and receives) and it doesn't take up my valuable MR-C3024 ports.

Hi,

Lots of talk, but no demos, no posted code, nothing but talk ...

If you have solutions, post the solution, how it's made, how it's done and the working code ...

The R/C solution works and most people have an R/C radio so it's much cheaper than buying a cell phone, figuring out new programming etc ...

The next cheapest solution would be a ZigBee with a PS2 controller and I still think that is the best solution ...

Monitoring all the other stuff is for people who don't have time to control their bot ... When playing soccer I concentrate on the soccer game, not my bots status ... when the bot stops, then I look at its status ... when it's moving I'm playing the game or concentrating on the bot performing other tasks ...

Status is for when the bot is down ...

PS2 controller? That sounds awesome. What's ZigBee?

Hi,

Goto the R/C Control forum thread and read the whole message ... click on the blue ZigBee link to read more ...

Good news I was running 4 Channel RC, Bluetooth and a Gyro (think I still had room for another gyro too but would have to check it again). So don't be disheartened you can run RC and Gyros no problems (Although I had definately removed the IR remote receiver)

Hmm, is it just me or do other find this post ironic?

And besides routine demos that I test with no controller/my computer, I also use bluetooth with a cell phone which enables me to use two gyros and a three axis accelerometer. I have two hole cutouts in my chest so i can adjust the gain of the gyros at any time. It is also possible to change a speed varaible via the phone, and have a nice gui so that i can have a huge variety of moves so unlike a ZigBee linked PS2 controller and R/C i am not limited to a few moves or many combinations.

As for the monitering, what? The gyro settings and accelerometer readings would be of utmost importance, lets say for example your playing robosoccer and you keep getting knocked down by other robots. (because:

I don't see a need for a side-2-side gyro

) But why not have a setting that you can switch on via the phone that could up the gain of the gyros if the x (or y if you had that port...) axis of the accelerometer is hit too hard (ie: above 1g). This could give your robot ample time to react next time he was hit, and then, even if he did fall over you still have the port open, so using a three axis accelerometer it can stand up on his own. (wow)

Even Pev runs bluetooth via a PDA, and i would guess that he would have the robot sending back a constant status report including the accelrometer readings, gyro gain,perhaps eye colour, and why not? It is a highspeed connection for the robot to a cpu which can handle much more complicated algorithms. You could be using the accelerometer and gyros anti-derivative and trace the robots position from a starting point. Could you do that with R/C? I shudder to think of the lines of code and the lag time of the robot if you tried.

So CaptKill4Fun, where are your demos? Oh wait, they are amazing, in fact, great job on the shovels second try. The finger.

No really.

It's not always easy to find all the stuff on forums but even a quick scan I managed to find the following solutions and information and that excluded items like sonar and IR distance sensors, C3024 microcode discussions and much much more. Think its unfair to say there is just a lot of talk on here. There are many people working on and sharing a wide variety of solutions and information. I, for one, am indebted to the likes of SubPilot, BauerMech, Dhinsel, Morbious, Hivemind, Inaki, Barbar and so many many more (appologies if I have missed anyone out take it as my bad memory not a lack of gratitude).

It does take some looking for but it is here and then on top of that there is the WIKI (http://www.robosavvy.com/phpnuke/modules.php?name=Wiki&n=RoboDocs.HitecRobonova-I)

Sounds just a bit arrogant to me too.
Mr Bullit may have created all that software for personal use and doesn't have to prove anything if he doesn't want to. Why post all his hard work on a forum for some dumbass to find it ready served on a plate and criticise it. Even so, if you bothered to read his post to the end:

There is no place for comments like CaptKill4Fun's in this forum.

P.S. 1: Captain, is there any way you can post a reply that doesn't involve advertising your work? This specific post was probably by miracle an exception, but in the future, if you want to advertise fine, just start it in your own topic.

P.S. 2: Mobile phone control sounds awesome and has many advantages over R/C.

Well said Pev, thank you very much for saying that. Captain's words are somewhat offensive the first time I read it. I can't almost believe it, but maybe he did not intend to be sarcastic . But then I continue reading and found your greater wisdom. I like that. I learned so much from all of you people by just reading the forum every now and then.

Please continue talkin no matter what! That is the very life of this forum anyway.

Eh Bullit,

That is brilliant! First time I heard that. Thanks to you. It will be great if all of us would be able to use our celfones and smartphones for this purpose. I mean everyone must have a celfone these days to control our RN-1. Geeh it's really cool. I can do away with my PS2 controller (which is rather bulky if I go places) if I could have this one.

Please keep us posted

Hi,

Yes, lots of talk ... but bottom line, if he has a new solution why not share it with the robot community? Or does he think he's going to get rich? Or just impress folks? My demand was in response for his telling me to post all my bracket designs in CAD format on this forum ... but where was the support for that? RoboSavvy.com seems to harbor too much hate and too little support for new ideas! Why?

We need solutions to keep robotics growing as a hobby and as products ... NOT DERIDING each other which seems to be the only solution on this website!

As for talk:

The kit contains all the components and small items required to build and operate the robot. No particular computer knowledge is required in order to handle and program the robot, while excellent mobility is provided by its 19 joints: 12 leg joints, 6 arm joints and 1 neck joint. This high-quality model is assembled from a set of robust components to produce a modern, attractivemachine with more than twenty pre-installed movement sequences.

These standard functions enable the robot to carry out basic movements directly, such as walking and turning, as well as special functions including hand-waving and various poses, without requiring any programming. The robot can also be controlled using an optional 40 MHz stick transmitter with at least six functions, together with a suitable receiverand accessories.

Can anybody guess what the name of this bot is? The demo video was impressive ...

This might be a better choice than the Manoi ...
