3DEER... First Seminar.
Alsalam alikom wa ra7mat allah wa barkatoh
Today we held our first seminar at the faculty, we were really afraid cuz we felt we are not ready + we don't have a WOW thing to speak about + we just made the presentation and rehursal yesterday (from 11:00am till 12:30am)...
Al 7amd lellah the seminar was good and the professor liked it.

First Seminar Preparations - episode 1
el salamo 3alikom wa ra7amtoo ALLAH wa barakatoo
Its my first post on 3DEER blog, I really feeling very interesting to work in that project with my team mates that I really respect.
we prepared for that seminar in just 2 meeting, first one was at my home, Haytham was the first one to arrive with our lovely baby robot, It was the first time for us to meet, It was really a shock when I first saw him,as it was small, cuty,tiny little one :D, but we had a deal that we're going to do the mission to gether ISA, and I really trust him.
While waiting for others to come, three of us began to play together with my LEGO toys, as me and Haytham remembered our past experience playing with LEGO, we really had fun :D.
Mustafa arrived but rest of the partners couldn't make it that day, Brainstorming..., to make the presentation.
we made it :D, we gathered all what we need to write in the presentation and we wrote a draft, we said that we need to meet another time with the rest of the team to finalize the presenation and begin the rehearsal, Mustafa and Haytham left with the lovely baby...
Thank you ALLAH

3Deer is moving
Alsalamalikom wa ra7mat allah wa barkatohToday,
I can say 3Deer learnt how to obay its master (Me :D)
I spent few days to figure out how to make it work probably with my MSRS(Microsot Robotics Studio), I got almost all errors found online :D..PleaseScroll down, for some reason, the rest of the Post is down there....
| Action: Connect from NXT to PC Error Message: Line is Busy Resolution: Restart the Serial Port Service from ur Bluetooth Manage on the PC |
| Action: Sending msrs.rbt from LegoNXT Manager to the Brick Error Message: Cannot find needed files Resolution: Manually send the Config file in Samples\Platform\Lego\NXT\Resources to the Brick(You will still get the same error cuz of the start image and such things, u can ignore then or edit the msrs.rbt and choose one of the current images) |
| Action: Starting the Tutorial1 Dss Node Error Message: Invalid Serial Port / Unable to connect to Lego NXT Resolution: 1- Check ur Bluetooth connections to know the port given to you Brick and put it in the config page. 2- Disable the Second Serial Port in ur Bluetooth Stick manager. 3- Manually start the MSRS program on ur Brick.. it'll crash and close, try to start it again... |
| Action: Using Tutorial1 Error Message: The Bumper's message is not sent. Resolution: I couldn't figure out why till now. Howerver, Tutorial4 (which controls ur Motors) works very well.. |
| Action: Building RoboticsTutorialX Error Message: Cryptographic failure while signing assembly 'D:\Microsoft RoboticsStudio (1.0)\samples\RoboticsTutorials\Tutorial1\obj\Debug\RoboticsTutorial1.Y2006.M06.dll'-- 'Error reading key file 'c:\mri\main\share\version\35MSSharedLib1024.snk' Resolution: The default key file used for signing all the assemblies is calledmrisamples.snk and can be found at D:\Microsoft Robotics Studio(1.0)\samples. 1) Check your project properties, right click the project name inSolution Explorer and choose Properties. Choose the Signing tab and makesure the Sign the assembly checkbox is checked and the URL is D:\Microsoft Robotics Studio (1.0)\samples\ mrisamples.snk or..\..\mrisamples.snk 2) Go to the Build Events tab ad check the Post-build event command linehas the following parameter: /keyfile:"D:\Microsoft Robotics Studio(1.0)\samples\mrisamples.snk" 3) In the Debug tab, "Start external program", change it to be:D:\Microsoft Robotics Studio (1.0)\bin\DssHost.exe, and so the "Working Directory" to be: D:\Microsoft Robotics Studio (1.0)\Reference |
3DEER is moving around.. my family is just saying "Hey haytham, call your Baby"
That's all for now..

Ultrasonic Sensor tests
Alsalam alikom wa ra7mat allah wa barakatoh
Today, I've been searching around a little bit to know more about ultrasonic sensors...
I found some interesting tests (done by students for their project too) here...
My doubts :
1- The sensor's accuracy :
if two sufaces with small difference in Z Axis, the robot may c them the same which may lead to bad model..
2- The StepperMotor steps:
if the stepper motor uses large steps, then we will not be able to get accurate results
Conclusion after today's search :
1- The best results taken from the sensor is when the measured distance was over 50cm & below 200cm which is a good sign, the worest case error is +/- 3cm.. which is not bad...
2- No new about motors yet....
