The ER1 is a robotic base that is can be controlled via USB-Serial interface via a laptop as pictured on the left

Player
http://playerstage.sourceforge.net

Player is a linux based network server for robot control. Running on your robot, Player provides a simple interface to the robot's sensors and actuators over the IP network. A client program talks to Player over a TCP socket, reading data from sensors, writing commmands to actuators, and configuring devices on the fly.

Player works with MANY robotic bases out there. The original drivers for the ER1 were written by David Feil-Seifer, a Phd student here at USC. However, when Player was upgraded from v1.0 to v2.0 the drivers no longer worked.

I am currently reviewing the original drivers and attempting to make them compatible with Player v2.0
