Mark Crosbie over at www. The article provides detailed information how his NXTBee library works and Sample Programs to try out a few behaviors. The article also provides a nice explanation of how communications protocols are structured, and also talks about data types. Bluetooth is one of those harder behaviors to program. Based off a modified version of the NXT shoot bot, the automatic tortoise feeder has three main components: The touch sensor has a colored ball mounted in it which entices the tortoises to bite at it.

Once that happens the robot dispenses the food, and then executes the line following program for several seconds and stops. I found out about NXT after watching a lego nxt sumo bot instructions for formatting sent around at work lego nxt sumo bot instructions for formatting the cubestormer robot and thought immediately it would be fun to do a robot that could interact with our two pet redfoot tortoises.

Hard to say as I started and stopped several times? I tried a few different designs before the current one that all had various problems.

It took a while to figure out a way to mount the touch sensor in a way that would allow a tortoise to trigger it. The vertical mounted hopper and the irregular size of tortoise pellets makes the amount dispensed each time really difficult to control. My current idea is to try mounting the dispenser horizontally and use either one of the rubber treads or maybe a track from a lego technic set to dispense the foot more like a conveyor belt.

Also might try a different lego nxt sumo bot instructions for formatting to move the robot around than using a line follow, possibly the distance sensor and some simple wall avoidance?

Posted in Cool projectsNXT. I was hoping to have it finished over the Christmas break but had hit a small issue with driving the wheels with the new weight of the body. Anyway what I did managed to get up and running is the top half of Wheeer and the controller which is a Android phone Dell Streak.

I was utterly impressed with the Mindsensors. This means it bypasses your own code and you have no control over it. However, what I managed to do is reduced it down to a very simple program that sends messages to the NXT which you can deal with in your own program.

Code will be available soon once I have tidied it up. Head on over to the download pages to download the latest version! First of all, let me introduce myself: This project is the result of that. The car then drives in the direction the user tells it to, while remaining within a fenced off area where the webcam can see it. To learn how and find out more about this project, click the link below:.

It uses an iPhone in conjunction with an NXT. I then needed a way to communicate with the NXT robot and steer it. If I want the robot to go to the left, I dim the lower portion of the iPhone screen and if I want it to go to the right I increase its intensity.

Also, when the phone does not see a face, I turn the lower portion of the screen black. This tells the robot that it needs to not move forward and spin in-place until it finds a face. A loud sound is used to toggle between start lego nxt sumo bot instructions for formatting stop.

Code subject to change. Download the lego nxt sumo bot instructions for formatting version of the code! The NXT robot is able to line track and also climb a book that sits along the path. Does a 3rd party 3rd party driver make it a 4th party? I also added a driver for the totally awesome Mindsensors Touch Panel sensor and their very versatile Sumo Eyes sensor. Big thanks to Mindsensors for providing me with the sensors! The Touch Panel driver still needs a bit of work; I need to add the ability to calibrate it and allow the gesture code.

I tried calibrating it once and that really messed it up. A simple factory reset fixed lego nxt sumo bot instructions for formatting, of course, no permanent damage was done, just some mild panic on my side and me thinking I had killed my panel I was not a happy camper, trust me!

Deepak from Mindsensors had a quick fix which was actually in the docs, if I had bothered to read them a bit more carefully. R ead T he F ine M anual!
