If you want to defend your place you need the biggest, strongest jaws out there. The lower part of the program only moves the jaw when the detected object is at less than 30cm of range. I would wait a few months for the upcoming Mindstorms EV3 Set.

Just play a bit with the values of time and make sure not to force the motor by opening the jaw too much. Rebooting fixed the problem. In fact I think it is as simple as the first step. Maybe the jaws are moving on the other direction?

This program is a great example of how complex mxt can be split in simpler tasks and executed in parallel. I have had this one several times.


If you recall, when we wrote the program we configured the A Motor to move in one direction and then in the other for a small amount of timeā€¦ so check: Overall, it is usually not a good idea to add many threads to our NXT-G programs, just keep that in mind. The upper part controls the mindstroms of our Robogator so that it moves the crocodile forward if we are far from the detected thread until it is barely 20cm away.

Sorry, your blog cannot share posts by email. My kid loved it and the coding introduced the concept of parallel execution with NXT-G. It is a robot that imitate a crocodile and has a moving jaw and four legs which are used to patrol and defend a position. On a different thread we has the jaw operating much like the above program, when it detects ndt it opens and closes the mouth.

Beware with your fingers!. Now we build the body of our Robogator, just make sure you plug the motor in the correct way. So, put your plans to conquer the world to a side and keep reading.

It is a bit blind sometimes so make sure that it is something big. This program just moves each minddstorms until it touch the press sensor and then it does detect anything it will launch our crocodile forward for a few turns and then back again. The overall gain here is that our Robogator will end with the legs on the foot each time it moves.


Did you turn on the NXT Brick? It is a cool robot to build and quite big! The color will change.

Is the USB cable plugged? Next, just write the program to open and close the jaw in NXT-G application. I suggest you change the motor power from 75 to for a more cool looking moving jaw that really bite! As with ShooterBotthe task of building the complete robot is split in steps that are easier to achieve.

Of course, just make sure that you plugged it correctly Port 4 and that you added the Wait Block for it. On the other hand, the lower part of the program takes care of moving the jaw.
