Linear Solenoid Actuator The Linear Solenoid Another type of electromagnetic actuator that converts an electrical signal into a magnetic field is called the Linear Solenoid. The linear solenoid works on the same basic principal as the electromechanical relay seen in the previous tutorial and just like relays, they can also be switched and controlled using transistors or MOSFET’s. A “Linear Solenoid” is an electromagnetic device that converts electrical energy into a mechanical pushing or pulling force or motion. Linear Solenoid Linear solenoid’s basically consist of an electrical coil wound around a cylindrical tube with a ferro-magnetic actuator or “plunger” that is free to move or slide “IN” and “OUT” of the coils body. Solenoids are available in a variety of formats with the more common types being the linear solenoid also known as the Linear Electromechanical Actuator (LEMA) and the rotary solenoid.

NXT Programming Software NXT Programming Software These are different ways of writing programs that will execute on the LEGO NXT brick. This list doesn't include all features, but should include enough information to provide a good starting point for you to figure out which software best suits your needs. Notes (1) RoboLab and RobotC both use firmware that comes Standard with some LEGO software Software Suggestions If you're looking here to find the "best" software, it's not that easy. NXT Off-Brick controllers (Remote Controls) These are different types of "remote control" systems for the NXT. (1) RobotC uses firmware that comes Standard with some LEGO software (2) LEGO's Mobile Application can send messages to a program running on an NXT Other Team Hassenplug NXT stuff
LEGO 9V Technic Motors compared characteristics See also this comparison page. Thomas Avery has also performed measures on 5292 motors, see Lugnet thread. The roster Weight Supposed to be equivalent to 71427, 43362 motor is 30% lighter. This is generally an advantage, except when the motor is used as a counterweight, or to balance the structure, for example in COG-shifting walkers. No-load characteristics Test conditions: motor is powered by a variable, regulated power supply. 43362 has a higher no-load current than 71427, probably caused by higher internal friction. 47154 has a fairly high no-load current, because of its 5-stages gear reduction. As is usual for DC motors, rotation speed is proportional to voltage applied to them, this can be seen on graphs below. Stalled characteristics Stalled current consumption is simply measured with motor axle shaft locked by hand. Take care to avoid extended period stall condition, as power dissipated in motor case is quite high (6 Watts for 2838, 3 W for 71427) will cause a rapid temperature rise.
Linear actuator Conceptual design of a basic traveling-nut linear actuator. Note that in this example the lead screw (gray) rotates while the lead nut (yellow) and tube (red) do not. Floppy disc drive with leadscrew and stepper motor. A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers, and in many other places where linear motion is required. Hydraulic or pneumatic cylinders inherently produce linear motion. Types[edit] Mechanical actuators[edit] A mechanical linear actuator with digital readout (a type of micrometer). Roller screw actuation with traveling screw (rotating nut). Mechanical linear actuators typically operate by conversion of rotary motion into linear motion. Some mechanical linear actuators only pull, such as hoists, chain drive and belt drives.
LEGO MINDSTORMS Internals A note to the reader: some of these links may be unreachable. I'm leaving them here if only to give credit where credit is due. Newer items are added to the bottom of each section, so look there for news. The LEGO® MINDSTORMS(tm) (#9719) product is a robot-kit-in-a-box. The LEGO-Robotics Mailing List A group of people have figured out how to talk to the RCX from operating systems unsupported by The LEGO Group. This group of people gathers at the lego-robotics mailing list. General MINDSTORMS Info You can buy the MINDSTORMS RIS (Robotics Invention System) at the stores listed below (presuming they have it in stock), and many fine toy outlets. Places to buy MINDSTORMS (not a comprehensive list): Erik Brok has an introduction to programming with MINDSTORMS page. Kin W. Books Jonathan Knudsen has written an O'Reilly book on LEGO MINDSTORMS. Michael Gasperi has, with Dave Baum, Ralph Hempel, and Luis Villa, written a book entitled Extreme MINDSTORMS. Joe Nagata's LEGO MINDSTORMS Idea Book Notes
Nils Völker - Robotics - Spherical Robot This is a ball-shaped "robot" based on a Lego Mindstorms NXT. It moves in any direction by simply rotating the internal mass horizontally and vertically. At the moment it's remote controlled via Bluetooth from a second NXT. So to be precise it's actually not a real robot more kind of a Rolling-Orbital-Bluetooth-Operated-Thing (to make it short: robot). But seriously: It's planned to implement the ability of moving autonomously later on. And to answer the most obvious question right away: No, there is no deeper sense or purpose, but a lot of fun driving it.
