JavaBots Revision History

• 25 July 98JavaBots 1.9b
  • Bug fixes.
• 20 July 98JavaBots 1.9a
  • Added capability for soccer robots to detect scoring events (see SocballSim).
  • Bug fixes.
• 6 APR 98 JavaBots 1.9
  • Now includes support for real TCP/IP communication between robots. Implemented using a client/server approach. RoboComm is the server, client is implemented in TransceiverHard. The Transceiver interface also works in simulation.
  • Reworked much of the code in the abstractrobot package. This should be transparent to most users.
• 1 MAY 98 JavaBots 1.8b
  • Includes entire source tree. Previous releases did not include JavaBotSim.java and a few others.
  • Distribution 1.8b includes a few additional soccer teams in the JavaSoccer/teams directory.
• 23 FEB 98 JavaBots 1.7
  • Added the JavaBotSimNoGraphics application. It allows you to run a simulation without the overhead of graphics. It's about ten times as fast as with graphics.
  • Some incorrectly named methods, like "TakeStep()" were deprecated. The first letter in these methods should be lower case to conform to Java coding standards. The old names still work, but you'll get a "deprecated" warning when you compile.
• 4 FEB 98 JavaBots 1.6
  • Added the ability to view robot ID numbers, robot state and robot trails in JavaBotSim. For example use of state, look at the Forage and Pebbles demos.
  • Implemented an inter-agent communication interface for SocSmall and MultiForageN150 robots. For an example of robot-robot communication, look at the CommTeam in JavaSoccer. For a definition of the communication interface, look at communication.Transceiver .
  • IMPORTANT NOTE: if you implemented your own SimulatedObjects or simulated robots, you will need to implement a few new methods described in the SimulatedObject interface. Robot control systems are upwardly compatible.
• 2 FEB 98 JavaBots 1.5
  • Fixed bug in JavaBotSim that sometimes caused objects to be created twice.
  • Added feature that enables developers to extend control systems and robots defined in the abstractrobot package. Previously, if they wanted new functionality they had to revise the existing classes.
  • Added a communication package that defines Messages and a Communication interface for robot hardware. The next release will include an implementation of communication in most of the simulated robot types.
  • Created the JavaBots FAQ.
• 29 OCT 97 JavaBots 1.4
  • Fixed problems that may have been causing NoClassDefFoundError errors in JavaSoccer. We'll see...
• 27 OCT 97 JavaBots 1.3
  • Added "maxtimestep" variable in description files. This enables the user to limit how far forward the simulation can go at each step.
  • Corrected comments in description file examples.
  • Cleaned up learning package.
• 13 OCT 97 JavaBots 1.2
  • IS Robotics Pebbles simulation support. To see this capability demonstrated, go to the Pebbles directory and type "demo".
  • Fixed problems folks were having with corrupted zip files. This could have been caused either by an older version of zip that we were using, or our Apache web server. We've addressed both.
• 9 SEP 97 JavaBots 1.1
  • Simplified CLASSPATH, now you only have to point to your java directory.
  • Improved the troubleshooting section of this page.
• 20 AUG 97 JavaBots 1.0 initial release.

• A real manual.
