I've been told that originally you could turn on the Powerbot, and then you could start the PC with a separate switch if you wanted. I would like to return it to this, and would like to know if there is configuration parameter to set this, or if there is some hardware fault, e.g. a relay has gone.

Has your Powerbot ever been modified or repaired? If so perhaps the computer switch was bypassed. You can also examine the computer power switch to make sure it has not been damaged or modified. What is the serial number of your robot? Thanks Reed iiw at deakin.edu.au wrote: > Hi, > > I am using a Powerbot, and the PC turns on when the Powerbot is turned > on.

Here is the test: the P3-X is commanded to rotate one round. For this purpose, the linear speed is set to 0 and the turn rate is set as non-zero. I am using Player and wrote the client program with libplayerc++. The quite mysterious phenomena is when the turnrate value is 15 degree/sec or less, the robot moves in a jerky way, i.e., it suddenly stops a while roughly every 2 seconds during the rotation. If the turnrate value is above 15, then the robot moves smoothly throughout the whole round turning. Furthermore, every time when the P3DX robot jerks, it also gives a beep sound. After searching threads in the nabble forum, I thought that was the safety watchdog inside P3DX is working, so tried to set pulse value inside .cfg file to different values like 1, 0.5, 0.1. Yet no any luck. I keep wondering whether the P3-DX robot has any further safety mechanism other than the safety watchdog, which exerts special constraints on pure rotation. I tested the same program on two P3DX robots and the jerks appeared in both cases. Here I attached the program I used (they are very simple in terms of player programming, no sensor reading, just keep sending command to robot using SetSpeed(vx, vw)), hope that somebody could help to test this on a real P3-DX robot and check whether the jerk appear or not during the rotation. thanks in advance clark -------------- next part -------------- An HTML attachment was scrubbed...

When a stall happens the robot will beep and try to stop. There are stall parameters in the firmware that you can find in the Pioneer 3 operations manual. There's also more details on what stalling means and does. There are bits that indicate if things are stalling, but I don't know if/how those show up in player (Reed probably knows but he's on vacation this week). You may also be able to adjust the rot PID parameters to avoid the stalling, there is more information on those in the user manual too... you can set them in the firmware CF program or with direct commands, but again I don't know how you'd do that with player. I didn't try your program, but I did fire up a DX and try and rotate at 5 degree/sec and 1 degree/sec and both worked fine. I did get beeping because the battery was low, but it wasn't at all jerky. The low battery beep and the stall beep also sound different (there should be more information about that in the user manual too). I did this test using the Aria demo in microcontroller command mode (d) and then doing '9 5' for 5 deg/sec and '9 1' for 1 deg a second (or '9 -5' and '9 -1' for negative). This was an unloaded DX though, and if you had a lot of weight it might be a different story.

From muhrix at gmail.com Thu Aug 27 16:34:15 2009 From: muhrix at gmail.com (Murilo Fernandes Martins) Date: Thu, 27 Aug 2009 21:34:15 +0100 Subject: [Pioneer-users] usb to serial and ARCOS Message-ID: Hello all, I was just wondering if I'm the only one who is experiencing some problems when trying to use ARCOS with a USB to serial converter (FTDI chip) on linux. I managed to connect to the robot and retrieve (corrupted -- with funny characters) data from the firmware. However, the first attempt to write caused ARCOS to crash and I had to flash the whole firmware from another computer using a "proper" serial port. For the records, the same USB to serial converter works fine to connect to the robot using ARIA. Many thanks! Murilo -------------- next part -------------- An HTML attachment was scrubbed...
