Then connected the robot's serial to the serial of the BOX.</div><div><br /></div><div>BOX description: </div><div>port 1 - still waiting for the Arm </div><div>port 2 - still waiting for the LRU</div><div>port 3 - Robot</div><div>port 4 - Laser</div><div><br /></div><div>Then installed the windows drivers for the BOX and saw that it maps the ports to COM13-17</div><div>After spending 2 hours the previous day, trying to figure out why ARIA can't connect to the robot, even thought i was specifying the ports ( -rp COM17) when running the .java</div><div><br /></div><div>Rolf discovered the problem. Windows is not happy when the port number is greater than 9. </div><div>So today I went into the Device Manager -> Advanced and choose ports 1,2,3,4. Some were showing In USE, but do not worry just choose and confirm. </div><div><br /></div><div>First found the Robot and then the laser, there is a soft restart for the laser each time ARIA connects to it, so waiting for 10-15 sec. </div><div>I was able to log the laser reading using ArLasserLogger() - it takes the robot instance, filename, start_angle, end_angle, see Docs for more explanation. </div><div><br /></div><div>I was not able to get the robot to wander, not relying on the sonar sensors, but I got it working on the Aria Simulator and I want to try if the recorder map can be read by MobilEyes. </div><div><br /></div><div>For now I am using my 6 years ACER Laptop running Windows XP, SP3, the battery is bad and It heats up a lot. I am looking forward to the new laptops as well as for 2D Robotic Arm and LRU. </div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2659266551585619375.post-33602193629413717582010-05-04T05:50:00.000-07:002010-05-04T05:59:29.481-07:00Building Aria in Java ++I thought building the java examples would be a 5 min task, but it turned out that in NetBeans creating a library and including the library path is different than adding the jar as library ?!.<br /><br />The other obstacle was having 64 bit Windows 7, I tried forcing Windows 7 to run NetBeans as Windows XP, but Java is too smart and still used the 64 bit, where Aria's jar is 32 bit.<br />To solve this problem I tried 2 things:<br />-recompile aria's jar to 64 bit - FAILED<br />-force NetBeans to use 32 bit - GOT too LAZY<br /><br />so my solution was to switch to my other computer (32 bit Windows XP SP3)<br />There was no problem there.
