Thanks for all the good information.

I am going to get back to my create 2 soon.

Here is some additional info about modifying the dust bin to add a caster on the Create 2 (Roomba 600 series)

Hi Rick, Thanks for the update. I'm glad the relay worked for you. I'm going to try that now. I have been using a servo to push the Clean button

I noticed you had reported the problem on Robotics.StackExchange and several others had the same issue. The iRobot employees on that forum just seeem to think its bad cables

Recently I have been spending a lot if time trying to get the BRC pulse method to work per the iRobot Create 2 OI spec

My testing has shown that this does REALLY work BUT ONLY IF

• the robot is sleeping undocked, i.e. not charging
• the robot is fast charging, i.e. not trickle charging as it is most of the time

I could force a docked sleeping robot to respond by turning of the power for 2 minutes for the power supply caps to discharge, but this is not dependable method for a telepresence robot

Thanks, Frank

Hi Frank,

thanks for the link to files for bin mod. Unfortunately I have been buying up used, broken down Roombas and people keep the dust bins!

When I get a dust bin I will print and use.

What is the max weight are you putting on the unit?

@rbonari, I took the inner lid off and here is a picture of what I see

I checked the contacts on SW5 with an ohmmeter and it seems that either set closes on a depression of the switch.

Which contacts did you use?

Not a fun disassembly...

Thanks, Frank

As I'm working on my Roomba based telepresence robot, I noticed that most of the commercial telepresence robots just rely on a remote operator to drive them around... no SLAM until you get into the expensive models.

and my current design supports remote operators just fine... but not much fun navigating remotely through a limited vison camera located 1000 miles away

While I wait for the availability of the EZ-Robot Lidar with SLAM, I thought I'd play with a simple waypoint to waypoint navigation approach.

Nothing really exotic here, just using multiple Roomba docking stations... not a practical solution for a large environment, but possibly OK for getting from a charging dock located out of the way of foot traffic to a location near a senior on a couch for a 2 way video chat... just manually back up a bit from the final dock to get a good video chat view

A great feature of Roomba is its ability to find and home in on a dock with a 6 foot radius... and the dock can be moved without remapping.... not easy with SLAM

@faengelm,

Check and make sure to use the side of the switch that when you press it you get the lowest ohm reading and when you let up it reads open. It has been awhile since I did this. Just make sure and test before you put back together. Also I would use thin wire like wire wrap wire so that you can route it up through the top cover easily....Rick

Nice work @Frank. I wonder if it is possible to tap into the iRobot virtual wall and that way you can put them in various locations to resync your location.

In reality what we really need is the LIDAR working and a SLAM of the environment and then feed that data into the Unity plugin the team is working on in the other thread. There are commercially available LIDAR now for < $100 so I have to imagine EZ-Robot can just take one of these and adapt their plugin to work with it.
