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).

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
