Re: GELway - Self Balancing Robot with Self Reset

Hey, sorry haven't been on here in ages. The source code for the robot can be found at http://code.google.com/p/gelway/ As for disabling the EOPD sensor, let me know if you still need help, and I can revisit my code, it's probably written in my thesis somewhere, it's been a few years

Hey Phillip, the LQR was one of the harder things for me to understand. I best it off the NXTway-GS documentation, it should be floating around in one of my references. My superviser for the project was like a Control Systems guru so he sought of steered me through the LQR. I used Matlab to determin...

Hey All

Hey Phillip, First off sorry for lack of replying. I've since left uni and have started an engineering course down in Melbourne, and have very little access to the internet. Also I had to hand over my robots back to the school, so I am not programming with them anymore. Just quickly reading over you...

Hey helifreak (always feels weird using user names haha), I am glad you got it working, makes me happy to know the robot is getting out there, since I put so much time into it. For anyone interested I passed my thesis =). Results came out yesterday, and got the marks I was after so I have been celeb...

Hey kellogg, I am really unsure as to what the problem is now. I have had a few people load my code now and they haven't had too much trouble getting it to balance. It is true that every motor is slightly different but they shouldn't be so different that they are not getting enough power sent to the...

Kellogg, Just to clarify, when you run the gyro calibration make sure the robot is perfectly still, i usually leave it flat on the ground. You should get similar gyro readings each time. In the GELway.java class file all you have to do is comment out the Bluetooth lines. You will also need to remove...

Hey kellog, My first suggestion is to comment out the Bluetooth connection. You don't need it to actually run, just to see if you can actually balance the robot. You should go straight into the gyro calibration, and enter should start the balance (also if your gyro calibration returning an actual va...

Hey kellog, Not sure about the 5kb smaller. It's probably to do with what behaviours I had active when I compiled. In regards to the Leight Sensor and EOPD sensor, you will need to pay attention to this value private final int eopdThresh = 1022; I haven't use the lightsensor. What you will want to d...

Hey kellog, It doesn't actually matter what bluetooth connection you use with the robot. I have included a PC controller that should be able to be loaded with PCCOMM.jar file. I used leJOS 0.8, I don't think there will be any issues with leJOS 0.85, however I beleive some things maybe in differnet s...

Hey Egone, I recently just finished my university thesis. I modified an old Java mobile application to sent integer commands to the NXT. You can check it out here, go to the downloads section to get the Bluetooth stuff. http://code.google.com/p/gelway/downloads/list The application basically connect...

Hey Hey, A bit more info might be helpful, but I am assuming a few things, if it is otherwise you can correct me, - The pellets are all the same - The robot knows where the location is to stack the pellets LeJOS has a behavioural system which may be useful for this task, this is how I would see your...

Do you only have access to one NXT. I am finishing off my thesis in a few weeks time, I worked on building a balancing robot, implementing a behavioural system and Master/Slave control of two robots. Towards the end of my project I started looking into joint decision making of two robots. So basical...

Hello, In regards to the phone I have had no problems at all with communications. I used a program called NXTSymbian that I found from the net and modified it to send integers to the NXT instead of byte commands. The phone I am using is a Nokia 6220 with Symbian on it. Although the install file is a...
