Roomba 535 Movement Panel

Skip to comments   Jump to end

Hi Again

I have a roomba 535 and I hooked up my EZB v4 to it per the instructions on the website and started the ARC software with the Roomba Movement Panel. I took the PS/2 wire and connected to servo wires at 3 & 7 ports mentioned in the instructions. Also, I have the EZB v4 connected to my existing Wi-fi network as a client. As I clicked on init in the roomba movement panel, nothing happened on my roomba and I am unable to move it using the controls. I checked the connections and everything seems to be connected ok. Can someone please help me diagnose this and help get my roomba working on the EZB?

Thanks!

Upgrade to ARC Pro

ARC Pro is more than a tool; it's a creative playground for robot enthusiasts, where you can turn your wildest ideas into reality.

Good idea R.R. However I'm wired up and committed to a Dirt Dog for now and quite happy with the results so far. Further tests will reveal what is really going on with the higher baud rate and TTL interface in the 500 and up series Roombas.

I switched over to sending commands to the 500 Roomba using Serial port 0 with much better success.

@Robot-Doc - Can you please let me know how do I manually change the port in the roomba Movement Panel to the Serial Port? It shows D0 and does not allow me to change it in ARC. Would I have to create a brand new Movement Panel and if so, I would then loose the ARC. automatic buttons for clean, dock etc?

@DJ - Appreciate your guidance on this as well.

@SarajG... You can send serial on all of the 24 ezb4 ports... If you want to send and receive you can use the UART ports... There is a black dedicated UART Port (0) on the ezb already (see the learn section for it's location) or you can send on D5 and receive on D6 (UART port 1) or (UART port 2) send on D18, receive on D19....

Edit Never mind, I thought he might want use the custom Movement Panel where he can change the post designations to anything he wants...

@SarajG, presently there is no option to change the Roomba pre-defined Movement Panel port that the commands are sent over.

What can be done (I think) is to use the UARTWrite commands with the right values to perform similar actions like the present Roomba movement panel.

Richard & Robot-Doc,

Thanks for the feedback. I was just wondering if there is a tutorial on the UART Write commands I can go through to familiarize myself. I would have to modify my servo wiring cable (as in my picture on post#1) is currently on D0 and I wasn't sure how to wire it to the black UART port on the EZBv4. It would be nice to have a snapshot of the wiring diagram :)
