 | | Severe Case of Alkaline Battery Leakage
|
|
I've got Duracell Coppertops on 10 NXTs I use in class. I've just experienced a nasty case of battery leakage. Good thing it leaked on the cover rather than on the electronics. Good thing the student, an 11 year old, brought the leakage to my (...) (18 years ago, 22-Aug-06, to lugnet.robotics.nxt)

| | NeXTTool fix & NBC update
|
|
I have updated the zips for BrickTool and NeXTTool to fix a small problem with downloading .ric files to the NXT brick. I also uploaded a new beta for NBC which implements a pseudo wait opcode (which was dropped from the firmware at some point). If (...) (18 years ago, 21-Aug-06, to lugnet.robotics.nxt)

| | New NXT Utilities
|
|
I have posted a couple new utilities for the NXT on my BricxCC website. One (MidiBatch) is a batch conversion utility for converting MIDI files into NXT Melody (.rmd) files. NXT Melody files can be played via NXT-G simply by renaming them as NXT (...) (18 years ago, 16-Aug-06, to lugnet.robotics.nxt)

I took my floor cleaner robot, Rosie: (URL) a two-block NXT-G program (in a loop): (URL) created a robot that I think has the accuracy of "Peeves", as seen here: (URL) appears to return within a couple cm each time.

(...) My problems with this solution are two-fold. First, NXT-G currently can't send anything back to the PC, as it's not running anything to get the NXT-G message structure (yes, folks could write this... almost certainly will. But likely not me).

Here's an idea of how to get more than 3 NXTs connected via Bluetooth (BT). It involves using a PC as a "relay point". I think standards allow up to seven simultaneous connections per BT device. The limitation to three connections on the NXT may be (...) (18 years ago, 13-Aug-06, to lugnet.robotics.nxt)

(...) I've played with it a good bit. It seems to be extremely accurate, in that one motor will slavishly follow the other - you can do demos like set a Move block to drive forward 10 rotations, and while it's trying to do that pick up the robot and (...)
