See and discover other items: big robot The LEGO Power Functions system has more possibilities and hidden functions than you probably think. I will show you a few examples. Some of them are well known, but others don't. You can use a 9V train controller to connect any Power Functions element. To do it you only need to add an empty battery box between the controller and the IR receiver All Power functions have a written code with numbers and letters.
20K3: 20th week of 2013 The PF system has a double wire connection: - One always on for IR receivers and servos. - Second one to control motors and lights. With the PF lithium battery you can control the speed of the second one, keeping the other one always on. Using this double function you can do two things at the same time using the same battery. I used this function for my Porsche 911 4 years ago ;) This looks complex, but it has an important benefit: IR receivers are very delicate under heavy stress, and with this mechanism you protect them. The PF Switch (pole reverser) has many possibilities. You can use it like a extension wire or as a motor controller. And using the same double wire system as the previous tip, you can control a motor using the same wire. All LEGO 9v and PF motors are actually a 12v motors. LEGO use them to avoid you break them under heavy stress. So you can use it as hard as you want, it is almost impossible you break any of them.
I have never broken a LEGO motor and I use them very hardly. The PF Train Remote controller is usefull to control the speed of a motor. But there are two ways to stop a motor started by train controller. You can use the red botton of the train controller, or you can use a starndar PF IR controller. You can connect tons of motors to the same battery box. But only if they are not under load. If you load one of them the battery power protection will cut the energy. A Lithium battery can handle up to more or less 12XL motors, a AA battery box some more... You can connect a IR receiver to a IR receiver, and both will work perfectly. Using again the double wire system. You still will have 4 free PF outputs. I used this in my Beetle If you connect a PF motor and a PF servo to the same IR receiver output, both start at the same time. But the servo will not stops until the motor are stopped. Some M motors don't work properly with some V1 receivers
I have at least 3 M motors from different years with the same problem in combination with receivers V1. Theses motors have the same problem since they were new. If I connect these motors directly to a V1 receiver they don't work, but they do it if I place a extension wire between them!! That is very strange, the problem is related with the electric contacts. Of course if I connect the motors to the V2 receiver they works fine. A video showing all these tips:LEGO City Train Engine c/w Motor BRAND NEW from set 60052This time we have a fix for your WeDo motor! I bet some of you have faced this problem after using the WeDo motor too often. The wires in the cable get broken by the connector on the motor side after a lot of use and abuse. If this is your problem, then we found your solution. We have found a fantastic step-by-step video for the WeDo motor, also known as the LEGO M-Motor. First, thanks to Vadim Smilansky in Israel for providing this detailed video tutorial about fixing the broken cable.
If you like the video or if it helps to solve your motor problem, please stop by and say thanks to Vadim because without him we would have to buy a new motor! Esta vez tenemos un arreglo para el motor del WeDo! Apostamos que algunos se han enfrentrado a este problema luego de un tiempo al usar el motor del WeDo. Los alambres del cable cerca a la conexión del motor se revientan después de mucho uso y abuso. Si ese es tú problema, te tenemos la solución. Hemos encontrado un video explicando paso a paso todo lo del motor del WeDo, también conocido como motor M de LEGO. Primero, tenemos que agradecer a Vadim Smilansky en Israel por proveer un video tutorial tan detallado sobre como reparar el cable roto. Si te gusta el video o si te ayuda a resolver tus problemas con el motor, pasar y saludar a Vadim porque sin su ayuda tendríamos que comprar uno nuevo!MotorSet motor speed and stopping actionexpand all in pageLibrarySimulink Support Package for LEGO MINDSTORMS NXT Hardware
DescriptionThis blocks controls the speed, direction, and stopping action of the LEGO 9842 Interactive Servo Motor. You can use this block with the LEGO MINDSTORMS NXT Encoder block, which outputs the rotation of the servo motor.The Motor block input value controls the motor speed and direction.Forward: 1 to 100 (slowest to fastest)Reverse: –1 to –100 (slowest to fastest)Stop: 0Using the Stop action parameter in the block, you can configure the motor to coast or brake when it receives an input of 0 (stop). As a side effect, when you change Stop action from Brake to Coast, the servo motor requires higher block input values to start moving and to maintain speed. The following graph shows this relationship. This block automatically converts the data type of the dataYou do not need to perform data-type conversion on theIf you run a simulation of a model that contains this block without the target hardware, this block does nothing. See Block Produces Zeros or Does Nothing in Simulation.Use the Motor
Open the legonxtlib block library and copy the blocks shown to a new model. Connect the Encoder block to the Motor block and the LCD block, as shown.Double click the Motor block to open the block mask, and change the NXT brick output port parameter to B.Connect one servo motor to Port A on the NXT brick. Connect another servo motor to Port B on the NXT brick.Prepare and run the model on the NXT brick.Slowly rotate the wheel of servo motor connected to Port A in each direction. Observe the servo motor connected to Port B drive in one direction and then in the other direction as you input positive or negative values. Using the input value displayed on the LCD, observe that values larger than 100 or -100 do not increase theIn the Motor block, experiment with changing the Stop n the model on the NXT brick again.Observe that the motor requires higher block input values both to start and to achieve the same speed as when the Stop action parameter was set to Brake.ParametersNXT brick output portSelect the NXT brick output port to which the encoder is connected.
