I ordered mine from Target online. They had a deal for 10% everthing, so with
tax and shipping it still worked out to less than $250. The web site says
delivery for end of July, but I received mine on June 30.
So far have built only the demo Tribot and have been fooling with the
programming to see what can be done. Some things take experimentation as
everything is not fully documented. I need a place to ask questions/discuss
issues. Is this the right forum?
Current questions/observations are:
1) wrote a little program to make the bot twirl in place (one wheel forward
and one back at same time). Is there any real difference in starting one
moter after each other and starting them both in parallel? I can't see one.
2) I changed the prog to start when I clap and keep twriling until I clap
again and then change directions every time I clap. I noticed that the sound
sensor "bounced" like a push switch. I had to wait first for quiet and then
wait for noise before switching.
3) I noticed that motor power is not the same as motor speed. I set power to
1% and the bot would not move (too heavy) but if I picked it up the whells
would turn slow. So then tried to move slow at 100% power by looping many
times of 1 degree movement at 100% power but this was not a smooth motion -
it just jerked along forward. I wonder how to accomplish this.
4) I can't seem to get a parallel processes within a loop. The NXTG software
doesn't let me. Although I can make user block with parallel processes and
then put in a loop.
5) I can already see that I'm going to get tired of the graphical interfact
and will want to use a more normal programming system.
That's it for now.

| (...) If you check "Control: Power Power", the motor speed will be regulated. At very low power settings (<10) it may be somewhat unstable. This checbox is available with "Motor" block, not "Move" block. (...) Unfortunately, you're right... Philo (18 years ago, 3-Jul-06, to lugnet.robotics)

| I know that some folks already have gotten the NXT and have started playing with it, but I've yet to see anybody announcing such here, so I was curious. Also: should I direct new NXT users into the LUGNET forums? I'm already starting to get more (...) (18 years ago, 28-Jun-06, to lugnet.robotics)
