Any New Community Ezb4 Robots?

Question

Just checking to see if there are any new EZB4 Robots or conversions? I know it is just starting. I have been following Dave's posts. Can,t wait to hear from Richard R. I know it is a major upgrade. I have watching the tutorials. Just excited and looking forward. Waiting to learn more from the actual builders on the community. I wish I could follow older posts without remembering all the details. No second or third page on posts? Thank you

Hey Steve... Actually my first project with the V4 is to see if I can get 2 way serial (using the UART port) to work with the Create... I will post once I get it working... To be honest I am so excited about getting the V4 I really haven't thought much about any real projects with it yet... It's so elegant and pretty, kinda' makes me want to build a shrine for it instead of using it...

DJ Sures · Answer

There will be a 2 day control for the iRobot pretty soon. it's on my list - but time hasn't been my friend

Rich · Answer

Keep watching... I'm currently working 20 hour days at the moment (a few of those hours are spent taking breaks coming on here mind you) to catch up with a massive backlog I have but once that's done I plan to put my V4 to very good use I am currently torn between fitting it in Melvin (he could really do with it and it would give me the motivation to finally finish him) or using it in my Wall-E I stripped apart a few weeks ago (would be easier and quicker than doing Melvin). Either way, it'll be off of the coffee table and in to a robot soon.

No worries DJ, I was just going to play with scripts and the UART commands for now.... Funny... Once I migrated from basic controls to scripts (and thanks to you and Rich's help on using them)... I was hooked.... And If you can believe it, I am teaching a neighbours kid (he's 11) how to use ARC and the ezb... Up until this point RC was all he knew... I think I got him hooked... He's probably bugging his parents right now to buy him a Six....

Robot Doc · Answer

I know there are a couple of us with the EZB(4)s that want to use the Roomba and take advantage of the two way serial port to not only send commands but to also receive informational packets from the robot. This sounds simple but there are several steps involved in receiving data packets, decrypting the information into usable form and displaying understandable results. Simple reports like wheel tachometer readings and battery status that would include temperature and voltage level would be nice.

Dunning-Kruger · Answer

Hey Doc... Packets are sent back in 1 or 2 bytes (as you know)... I don't think I will have too much trouble with the 1 byte packets, however the highbyte and lowbyte (2 byte packet) probably will trip me up... I did get it working with my old controller (AtomPro)... Even the two byte packet too... However, I did have trouble until I got help from Basic Micro forum on how to do it...

Rich · Answer

@Richard, just think about what's happening with it logically, look over what commands are available and what they do and you'll figure it out. Although if there is a native control coming for the Roomba/iRobot then, other than as a personal challenge (some of my best work comes from me challenging myself to achieve something that's totally pointless) you may as well just use the control.

Robot Doc · Answer

Richard R, yep, I think we may get a whole bunch of help from DJ as time goes by. In the mean time I've decided to upgrade to the R3 7XX model Roomba which has no documented information at all but has some similar input commands and may still use some of the same data packets as the R2 Roombas and the Create. And I know Rich will help out if we ask him. We may have to bribe him with a Roomba, lol.

Richard R, You have been great on the EZ Robot forum and your builds. D.J.Sures. I can,t wait to see what you offer the community, thank you so much for your great work! So exciting! Rich, you are always helpful and very resourceful, thank you, I have wondering about MELVIN and how you might incorporate your experience into your interest? Robot-Doc, many great interesting builds, can,t wait to what you add? So many great people that will jump on this new technology.

Dunning-Kruger · Answer

Thanks Rich and Doc... And Doc, keeps us posted on your progress with the R3s... And Rich... Eat more fish buddy... We don't want to lose that brain of yours...

stonewolf · Answer

Well I am just waiting on the V4 kit and other parts I have on preorder, once things arrive I will be able to bring some life into my robot ROAMIN, I am very anxious to get him up and moving and then I can post some videos of my creation :-}

Jeremie · Answer

ROAMIN looks pretty good @Stonewolf can't wait to see him in action! The chair makes him seem monstrous but I'm guessing that without it, he's probably still 3 feet or so tall.

stonewolf · Answer

@Jeremie He stands around 3ft tall maybe a abit taller, but he solid and sturdy build, it well be something to bring him alive and to show others :-}

Steve S · Answer

Richard R, Your last info with EZB4 was you could not communicate with IRobot temp, rec. packet? I could not find your last post. Was there any response from EZ robot? Any new info about anyone receiving info from IRobot Create/Roomba using the EZB4? Robot-Doc also had some issues with IRobot. This is what I have looking forward to. Any details on wiring connections and new information? Thank you for any help. Looking forward to my EZB4. Steve S

Hey Steve, this was my attempt... I am able to send commands to the Create using the UART, but still no luck receiving packets back like batt temp and such... Below is/was my code... I haven't got back to it in a week since the post, so maybe a little tweaking might get it to work... Or maybe I am a way off base... LOL... To my knowledge, I don't think DJ or EZ Robot was able to look at it yet... Not complaining as and I know the EZ Robot team has bigger fish to fry right now. I know he has the Roomba stuff on his list so we need to be patient... Anyway, here is my code...
 # Using UART port 1 TX on D5 RX on D6 $x="null" $y="null" uartinit(0, 1, 57600) sleep(1000) uartWrite(0, 1,128,132) #Init iRobot create and place in full mode sleep(100) uartWrite(0, 1,142,24) #Query Roomba Battery temp in DegC... single byte sleep(100) #$x=UARTReadAvailable(0,1) $x = UartAvailable(0, 1) print("Bytes in buffer: " + $x) $y = UARTRead(0, 1, $x) print("Received: " + $y)

Steve S · Answer

Richard R, I appreciate your update. Thanks, Steve S

Dunning-Kruger · Answer

Ok, so I tweaked the code a little... Might be making some progress... I am at least now getting a response back from the Create, but the characters sent back are jibberish... it's like the baud rate is wrong or something. When I query the Create's battery temperature (as per a tweaked version below) I get back what looks like the letter Q instead of a number between -128 and 128... The baud is set at 57600 and works no problem sending the Create drive commands...The Create's default baud is 57600, which it is set at....
 $x="null" uartinit(0, 1, 57600) sleep(1000) uartWrite(0, 1,128,132) #Init iRobot create and place in full mode sleep(100) uartWrite(0, 1,142,24) #Roomba Battery temp in DegC... single byte from -128 - 128 sleep(100) $x=UARTReadAvailable(0,1) print($x) Halt()

I'm working on a throw it together style robot with a planned penguin paint scheme. It can be found here: synthiam.com/Community/Questions/5636 I'm getting votes on the name and on the head and now arms too. If you have any ideas let me know!

Dunning-Kruger · Answer

Ping Steve... Some success (thanks to DJ) ... Below is working code for the 1 byte Roomba/ Create data packets.. Still working on 2 packet data...
 # Using UART port 1 TX on D5 RX on D6 $x="null" :top uartinit(0, 1, 57600) sleep(1000) uartWrite(0, 1,128,132) #Init iRobot create and place in full mode sleep(100) uartWrite(0, 1,142,7) #Roomba Bump and wheel drop sensor sleep(100) $x=UARTReadAvailable(0,1) print(GetByte($x)) goto(top)

I will be powering Sunshine with the EZB4 (if it ever comes in).

Steve S · Answer

That is Great news Richard R getting some code operating that receives packet info from Create using the EZB4. When you sent the optcode 142 for sensors packet member 7 what value did it return? Was it 1 for bump left or 0 for bump right? I have never used something like "Realterm" before, only EZ Robot send serial commands. I always wanted the bumper sensors to be an emergency stop for my robot. If bump is detected then sendserial(D0,57600,137,0,0,0,0) #STOP The opcode wait for distance, angle, work great, but ignore all other commands until the wait is complete. The cliff sensors still operate when I move my robot with serial commands, telling it to drive forward stopping at the edge of a table while I waited to catch it. The IRobot Create and Roomba have many great sensors built in. Are you still using the small Create plug, but with the extra receive wire added? I know you are using UART port 1 TX on D5 RX on D6. Can you sometime show a picture of your wire connections on EZB4 side and Create plug. Thanks for sharing your info and helping. Steve S

Dunning-Kruger · Answer

Steve, I got 1,2,3.... depending where I hit the front bumper... bumper is something like left=1, centre =3, right=2... something like that... never tried wheel drop... You'll have no problem using my code to detect a bumper hit and as you stated to stop the Create or turn, backup or whatever ... I'll get you a picture tomorrow... but it is only 3 wires... ground on D5, send on the signal pin of D5 and receive on the signal pin off D6... I have made both a 7pin plug and a 25pin plug... both work perfectly for this.. in the meantime I am still working on getting the 2 packet info back...

Steve S · Answer

@steve, Captain Anne is Uptown! The thing I would add to her is her own win7 or 8 tablet. They will shrink them more someday soon so it will fit. I have one that might fit, but it needs to shrink some more. Well done.
