The hardware and software roots of the Mindstorms Robotics Invention System kit go back to the programmable brick created at the MIT Media Lab. This brick was programmed in Brick Logo. The first visual programming environment was called LEGOsheets.
The NXT version has three servo motors and one light, sound, and distance as well as 1 touch sensor. The NXT 2. 0 has 2 touch sensors as well as a light and distance sensor, and support for 4 without using a sensor multiplexer. Lego Mindstorms may be used to build a model of an embedded system with computer- controlled electromechanical parts. Many kinds of real- life embedded systems, from elevator controllers to industrial robots, may be modelled using Mindstorms. Mindstorms kits are also sold and used as an educational tool, originally through a partnership between Lego and the MIT Media Laboratory. In addition, the shipped software can be replaced with third party firmware and/or programming languages, including some of the most popular ones used by professionals in the embedded systems industry, like Java and C. The only difference between the educational series, known as the .
It contains an 8- bit Renesas (then a part of Hitachi) H8/3. CPU. It included 3.
K of RAM to store the firmware and user programs. The brick is programmed by uploading a program (written in one of several available programming languages) from a Windows or Mac computer to the brick's RAM via a special infrared (IR) interface. After the user starts a program, an RCX- enabled Mindstorms creation can function totally on its own, acting on internal and external stimuli according to the programmed instructions. Also, two or several more RCX bricks can communicate with each other through the IR interface, enabling inter- brick cooperation or competition. In addition to the IR port, the system includes three sensor input ports and three motor output ports (which can also be used to drive other electrical devices such as lamps and so forth). An integral LCD can display the battery level, the status of the input/output ports, which program is selected or running, and other information.
In version 2. 0 (as well as later 1. RIS 1. 5), the power adapter jack was removed. Power adapter equipped RCX bricks are popular for stationary robotics projects (such as robot arms) or for controlling Lego model trains. In the latter context, the RCX needs to be programmed with Digital Command Control (DCC) software to operate multiple wired trains. The IR interface on the RCX is able to communicate with Spybots, Scout Bricks, Lego Train, and the NXT (using a third- party infrared link sensor.) The RCX 1. IR receiver carrier frequency is 3.
What is the difference between the NXT and the RCX? I know that the NXT is newer, but what features does it have that the RCX doesn't have, and vice versa (if the RCX.
Hz, while the RCX 2. IR carrier frequency is 7. Hz. Both versions can transmit on either frequency. The RCX communicates with a computer using a Serial or USB IR tower. The tower is supported by Windows 9. Me, and XP (3. 2- bit). A patch is available for hyper- threading/multi- core CPUs.

There is no formal support for Windows Vista (3. The USB tower does not work on a 6. OS unless a 3. 2- bit OS is used in conjunction with a virtual machine. The serial tower works normally under 6. Windows 7 using a third- party USB- to- serial adapter. The first RCX produced is marked . Being a normal webcam, the Lego camera is, unlike most Mindstorms products, not programmable and is only usable connected to a PC or some other device that supports USB webcams.

The Lego camera is meant to be used with the included Vision Command software which can also interface with an RCX and thus enables creating robots with . The software is capable of detecting different lightings, motion, and colors. It can also be used with any other software that uses a webcam. The webcam is capable of recording up to 3. It also contains a microphone to record sound for videos.
V PC interface. It came with a dedicated IBM- PC- compatible ISA interface card, a ribbon cable, and a control panel. The control panel included six non- reversible 4. V output ports, three reversible 4. V output ports (each using the power lines from their two adjacent non- reversible ports), two 4. V input ports, and one continuous 4. V output port. It also features a manual- override stop- button.
Using programs running on the host computer, the user could create stationary programmable robotic Lego inventions using the older 4. V system. The 4. 5. V PC Interface was superseded by the 9. V- based Dacta Control Lab in 1.
Technic control center. It featured three output ports and manual control, and it was only capable of storing linear sequences of manual input plus timing information.
It could store up to two programs at once. The manual controls could be used to independently control the three motors.
To record a program; the controller had to be put in programming mode, and then any manual control would be recorded to the program. Pauses could also be included in a program. When the recording was done, the controller could successfully recall and execute any manual action done during the recording. The executing program could be set to loop infinitely. Compared to the later programmable controllers, the Technic control center is extremely simple and can only barely be called programmable.
Dacta Control Lab. The control lab was a datalogger, which featured four passive input ports, four active input ports, eight controllable 9. V output ports, and one continuous output port. It also featured a manual- override stop- button. The control panel connected to a computer using a serial- port with a specially designed adapter cable and a supplied computer- program allowed the user to conditionally program the outputs.
This allowed for robotic operation of mostly stationary Lego inventions. The Control Lab superseded the old 4. V PC interface from 1. Lego interface. The connectors of the early sensors were color- coded according to their type. Active sensors had blue connectors and Passive sensors had yellow connectors.
Later Pbricks kept the color- coding for the input ports, but the later sensors dropped the color- coding of the connectors (using black connectors instead). The early touch- sensors were also of a different kind and shape compared to the later touch- sensors. Most notably, instead of featuring a removable cable, the cable was fixed just like the other sensors. These early sensors also featured longer cables. The Control Lab was designed for schools and educational use and was as a result not available to the mass market. It was later replaced by the RCX and the educational release of the Robot Invention System which allowed for mobile inventions in addition to stationary inventions. Cybermaster. It was aimed at an older audience as an early attempt of merging with robotics and Lego.
The brick shares many, especially software, features with the RCX but differs in appearance and technical specifications: one output (plus two built- in) and four sensors. It uses RF (2. 7 MHz R/C band) instead of IR for communication. It has two built- in motors with integrated tachometers and speedometers. It is limited to passive sensors (a simple A/D with internal pull- up resistors). The sensors shipped with it are color- coded and have internal resistors in their open state (allowing the Pbrick to sense which sensor is attached to which port).
It has a fixed firmware (so it cannot be upgraded or replaced). It has limited RAM for programs (3. This unit was the first programmable brick (or Pbrick). It features a single motor, a single touch sensor and a light sensor.
It is programmed by setting it to 'learn' and using the light sensor to feed barcoded commands. The command set is very limited. Since barcode is just a series of variances in light, this form of command entry was dubbed VLL (Visual Light Link) and has been used in several later Lego models. Lego also released a blue computer called the Scout, which has 2 sensor ports, 2 motor ports (plus one extra if linked with a Micro Scout using a fiber optic cable), and a built in light sensor, but no PC interface. It comes with the Robotics Discovery Set. The Scout can be programmed from a collection of built- in program combinations. In order to program the Scout, a user must enable .
The Scout can store one program. The Scout is based on a Toshiba microcontroller with 3. KB of ROM and 1. KB of RAM, where about 4. Due to the extremely limited amount of RAM, many predefined subroutines were provided in ROM.
The Scout only supports passive external sensors, which means that only touch, temperature and other unpowered sensors can be used. The analog- to- digital converters used in the Scout only have a resolution of 8 bits in contrast to the 1. RCX. However, due to the complexity of this project, it was abandoned.
The RCX can control the Scout brick using the . The RCX does all of the controlling, and therefore can be programmed with the PC, while the Scout accepts commands. The Scout brick must have all of its options set to . It is a very limited Pbrick with a single built- in light sensor and a single built- in motor. It has seven built- in programs and can be controlled by a Scout, Spybotics or RCX unit using VLL.
Like the Scout, the Micro Scout is also based on a microcontroller from Toshiba. The unit was sold as part of the Droid Developer Kit (featuring R2- D2) and later the Darkside Developer Kit (featuring an AT- AT Imperial Walker). Spybotics. It consists of four colour- coded robots called Spybots, a programming language with which to control the Spybots, and ten simulated missions. Programming language.
