 | | Avoiding motor stalls
|
| I broke another 9V motor. See my (URL) post> for the first story. I'm building what amounts to a pitching machine for the Great Ball Contraption. In most TECHNIC building you're building a gear train to produce lots of power at the expense of speed. (...) (19 years ago, 9-Jul-05, to lugnet.technic, lugnet.robotics, FTX)

| | Re: Lego "style" wire and electrical connectors
|
| (...) As a purist I'll tell you that LEGO's educational store sells wires in 3 meter lengths along with the more typical sizes. However, I've had to make my own wires before, so . . . Official LEGO wire is pretty thin; I'd guess it's 24 guage. (...) (19 years ago, 16-Dec-05, to lugnet.robotics)

| | Re: Vehicle with square wheels

| (...) I built one similar to yours last night (I put gears on both sides as an experiment). You're correct that it's the gear backlash that causes the wheels to not quite turn at the same time. Pushing the wheels down manually with your finger is a (...) (19 years ago, 14-Dec-05, to lugnet.technic)

| | What should you do with a stuck motor?
|
| Last night I had a new-style 9V motor attached directly to a 40-tooth gear that was turning an 8-tooth gear. There was a fair amount of torque involved, and my motor stalled after a while. Now the thing won't turn unless I really force it. What (...) (19 years ago, 29-Jun-05, to lugnet.technic, lugnet.robotics, FTX)

| | Re: Vehicle with square wheels
|
| (...) Fantastic work. I hadn't even started my attempt. I like your using the battery box as the weight -- it's very simple and compact. I noticed from the video that it tends to veer left. Are the wheels losing traction when they're fully flat? (19 years ago, 12-Dec-05, to lugnet.technic, FTX)

The weight at the top of the vehicle (...) (19 years ago, 6-Dec-05, to lugnet.technic, lugnet.robotics, FTX)

| | Re: Design
|
| I imagine that if I were to ever design a robot's functions on paper first, I'd probably use a finite state machine, since FSMs map to events pretty well. The robot's functions would have to be complex enough to make it worth it, though. For code, (...) (19 years ago, 30-Nov-05, to lugnet.robotics, FTX)

| If Lego obeys the USB standard and uses fullsize receptacles, it'll be a "B" type connector on the NXT. Hence, you'd need a B-male to A-female cable, which is "illegal" according to the USB standards. You might hack up your own, but that's (...) (19 years ago, 6-Jan-06, to lugnet.robotics)
