I'm glad I could be of help.

Just a reminder for all people that have developed new stuff with their ER1, please upload to Dropbox so the other members can try it out. If by any chance you don't have an invite to the Dropbox account, let me know and I will add you.

Thanks to all,
Gabriel.

Can anyone tell me where I can get a copy of the software to run the ER1 as well as the ERSP software. I have an Er1 with gripper arm and all the extras but during move I lost software somehow. ER1 site isn't of any help as no emails are returned to me. HELP please.

Hello All,

I have been following this forum for quite some time, but this is my first post. I have owned an ER1 since 2004 and I think its a great robot. I am currently running it on a tablet netbook and a custom frame. My question is, in the API, the software does not recognize the 'er1' command. It gives an error message saying something like "Error- *<er1> expected: <move>, <set>, <play>, <speak>, <sense>, <etc. etc.>". In the manual, the first command in the API is the ER1 command which is supposed to allow you to run .rbt behaviors while in API mode. I have no trouble running all of the other commands, but that one has never worked. I have reinstalled the software many time since owning the robot and I am running the most current version of the software (thanks for the download link, btw). Has anyone run into a similar problem or am I just doing something wrong? Any advice or suggestions would be greatly appreciated,

Thanks

Hi GregoryL
I agree with you, the ER1 command is not recognized by the API.  Itís really too bad as it would be useful.  I wonder if earlier versions of the RCM software had this command enabled.

Hi GregoryL and Chewy,

Long time since I used ER1 API for the last time (now I use ERSP), but I remember that I was also fooled by the missing er1 command.

I realiced that er1 is not a command but the ER1 Control Center executable, so you can launch it with a behavior as argument. I called if from my Java client with

  Runtime.getRuntime().exec("er1 " + bhvName);

Cheers

Ron Berkowitz, author of ďAn Integrated Environment for Simulation and Control of Mobile Robots" (http://mss3.libraries.rutgers.edu/dlr/outputds.php?pid=rutgers-lib:30992&mime=application/pdf&ds=PDF-1) , has discovered an undocumented ER1 API command:

"move x (value) y (value) cm"

where the (value) was the distance you wanted the robot to move in the x and y directions, respectively.
I actually lucked out with this command. I had been having trouble getting the robot to move to any x-y coordinates without making it look choppy and was stuck on this problem for a few weeks. Then a light bulb went off in my head.
I figured the command out after looking at the given commands in the ER1 manual and deducing what the syntax would most likely be.


I gave the new command a try and am happy to report that it works.

Found my old ER1 in the basement and decided since I have a working laptop that has no screen, it may be fun to fire it all up again and see what I can do with it.

I just can't find any of the old software nor find any way to get it via Evolutions website etc.

Can anyone point me in the right direction?  Your help would be sincerely appreciated.

Thank you

I have an ER1, very gently used, with all the pieces (gripper arm, sensor pack, expansion pack, manuals).

Is anyone interested in buying it off me?

Hey everyone.  I am in need of the software updates for the ER-1, especially the power patch that keeps the bot from complaining about the laptop charger.  Is this in the drop box?  If so I guess I need access or someone to email them to me.  A bunch of 3rd graders depend on it!  ;D

Hi Griff

  You can easily stop the ER1 from complaining about the charger by adding a config.txt file.  Here is a post from the old Evolution ER1 forum which explains it:




Re: [charles] Advanced configuration options. [In reply to]  Can't Post 

--------------------------------------------------------------------------------
 
You can customize the configuration of the Robot Control Center by adding a config.txt file in the C:\Program Files\ER1 directory. You have to add the following section in this new file called [hardware] and add your directives underneath. For example, to log all movements that the robot makes, I'd add:

[hardware]
log_move=1

Here are all the configuration options that can be added under the [hardware] directive. There is no limit to the number of directives (you could have all of them if you wanted) Attached is a simple example configuration file.

------------------------------------------------------------
fov=(double): camera field of view in degrees(defaults to 42 degrees).

baud_rate=(integer): The baud rate of the command serial port (Defaults to 250000).

wheel_base=(double): Distance between the wheels in cm (defaults s 38 cm).

stop_when_charging=(0/1): If 1, prevents motion if the robot is charging.

disregard_low_robot_battery=(0/1): If 1, does not prevent motion even though robot is low on battery (defaults to 1).

disregard_charging_laptop=(0/1): If 1, does not prevent motion when the laptop is charging (Defaults to 0).

default_accel=(double): The default acceleration used for robot motion, in cm/sec^2 (defaults to 70 cm/sec^2).

left_motor_board=(0/1): Indicate which motor is connected to the left wheel (Defaults to 1, corresponding to the construction photos in the manual).

right_motor_board=(0/1): Indicate which motor is connected to the right wheel (Defaults to 0, corresponding to the construction photos in the manual).

left_motor_position_factor=(double): The position factor of the left motor. Should always be negative for the motors we're using on ER1. (Defaults to -1711).

right_motor_position_factor=(double): The position factor of the right motor: Should always be positive for the motors we're using on ER1. (Defaults to 1711).

log_move=(0/1): If 1, log all motion commands to the hwlog.txt file. (Defaults to 0).

-----------------------------------------------------------

-Charles

Worked like a charm, thank you!.  I took the liberty of adding a web control I found a few years ago to the drop box, hope someone finds it useful.

Hi,

I was wondering about two things.  Hopefully the second has not be rehashed to much...

I was wondering if anyone knows what the system dynamics of the er-1 are.  Maybe there are some papers or articles about it?

In addition, if anyone has used a recent version of Player with the ER-1, I'd love to know how!  I can't seem to get my robot working with Player.

Hey Guys, not sure who is still around tinkering with the ER-1.  as I have been reading this forum, and trying to locate some of the software i.e. python mapper, for one.  I noticed that there are some people are looking for a "gripper" sub. I have been thinking of an idea and wanted to throw it out there for you guys to think about.  using a DIY servo driver, and a simple software program to open or close the fingers ( with a switch on one of the fingers to stop the servo from crushing item ), attached to the "hobby ports".  I know the GUI allows you to run "external" programs... maybe we can make something to suit our needs.  I have most of the electronics figured out, the mechanical is still on the paper stage, and the software is on the back burner.... figure once I have it built, I can figure out how to drive it.  Any thoughts.  Also anyone got any current links to the latest RCC? as well as the python mapper???

thanks

Hey all,

My name is Snode2, and I'm working on a project over the summer that uses the ER1 robot, as well as some other modifications that include using other sensors such as motion sensors, light sensors, and others, as well as attaching a different webcam. I'm a high school student enrolled in some AP Computer Science courses, as well as some PLTW Engineering courses. I've been doing quite a bit of research, and I've found that a lot of the ER1 bots that have been built have used Player on Linux. I was wondering if there was a driver for Windows 7 at all, or even XP for that matter. Either one can work for the computer I would like to use with the ER1. Any help would be greatly appreciated.

Thanks,
     Snode2

I would like to be added to the dropbox too!!  I have an ER1 in the basement that I am going to bring back to life.   Anyone still tinkering with them?
