 | | Mindstorms question —Nathan Bell
|
| | | I bought the Mindstorms NXT kit at BrickFest 2006 in hopes of designing a Lego chipper. Although the sensors would make the design possible, the blade of a chipper has to turn at an extremely high RPM- and with a lot of torque. The NXT motors turn (...)

| | | | (...) Nathan, Yes, there are ways to do just about everything you asked. I don't think the RC motors will run at full power when connected to an NXT (which can be done via conversion cables) Personally, I'd suggest gearing up one or more NXT motors, (...)

| | | | (...) Thanks Steve for the information and the advice. Although gearing up the NXT motors may result in a loss of torque, it sounds like a good option. Another option might be to control the switch for the RC motor with one of the NXT motors (which (...) (18 years ago, 26-Jan-07, to lugnet.technic)

| | | | | (...) The NXT motors have built-in rotation sensors, so you could detect a stall condition with no other hardware. You could use the ultra-sonic (distance sensor) or light sensor to detect when the blade passes in front of it, to determine when the (...) (18 years ago, 26-Jan-07, to lugnet.technic)

| | | | Hi Nathan, (...) the RCX rotation sensor should work on sensor ports like all legacy sensors, provided it is supported by the firmware. It would also be possible to build a rotation sensor for the motor ports, i.e. like a NXT motor without the motor (...) (18 years ago, 27-Jan-07, to lugnet.technic)

| | | | (...) Thanks for the reply. If everything you say is true, I might use multiple white clutch gears on one axle, gear them to a differential and use the difference in torque to trigger a lever- which can activate the touch sensor. It sounds better to (...) (18 years ago, 31-Jan-07, to lugnet.technic)

| | | | | | Re: Mindstorms question —Nathan Bell

| | | | (...) Come to think of it; if the difference in torque triggers a switch, that switch might as well trigger the off switch to the blade motor. The whole thing could be done 100% mechanically without the Mindstorms kit. Bummer. Oh well; that kit will (...) (18 years ago, 31-Jan-07, to lugnet.technic)
