You've probably noticed that I've changed the name from racing truck to just truck. this is because there was too much friction and it was too big that having a fast gear ration didn't work well. So I did a 1:1 gear ration and focus on how controllable it was since the two motors were linked with a differential, so different speeds on the two motor…

This is my half tracked vehicle. It is remote controlled by the PSP-NX-V3. In "normal" mode it is driven by one joystick, it has no differential but when turning, the back two motors go at different speeds, simulating a differential. When you hold down the R1 button, it goes into "two joystick" mode where the left and right joystick control the tre…

I was a little disappointed about my results this year but I still did better than my first year (2011). I only got 1 trial correct but that one trial was the best trial I’ve gotten ever, but, due to chance/human error, trial 2 and 3 were a fail, lowering my score. Trial 2 seemed to fail due to a shake of some sort. I slowed down that part in the v…

This is the final version of the crane. as you can see the base was well improved from the last one, the turntable stays securely connected to the base, the worm gear slips less, it doesn't tip over as much and when it does it doesn't break as much. I also made a spot to hold the weight.Program:Nothing special about this program really but you can …

The other change is the instructions for NXT 2.0.ProgramsForklift programs for NXT 2.0These programs are made for the forklift when using the building instructions. In each program it limits the top and bottom so tha…

This was my first attempt at an off-road vehicle and I think it came out pretty well. it is build-able with 1 NXT 2.0 kit (minus the wheels) and if you change the gears, you can build it with NXT 1.0.Hardware:I used only a NXT 2.0 kit along with 4 wheels I borrowed from a friend, this worked without borrowing wheels but these wheels make it work mu…

I’ve setup two testing areas, first on the deck with a carpet but the carpet made the turning unreliable so i was not able to test the turns well. Then i set it up the in the kitchen and i got it to work after playing with it. The only downside with the setup in the kitchen is that it has to come down once i’m finished testing and it only shows the…
