Color sensor nxt robot kits
HiTechnic one has a white LED, and a specialized color sensitive chip. This chip has three sensitive areas covered by red, green and blue filters. An added advantage of HiTechnic method is that it can detect the color of light sent on it in passive mode, with the white LED shut off.
This test was performed with the setup pictured above. Six colored plates are mounted on a NXT motor. They are successively shown to the color sensor, and the color read is recorded. In order to test reliability, this cycle is repeated 10 times at each distance.
The triangle shaped support allows to change the angle between the plates and the sensor. Note that the NXT-G block provided with HiTechnic color sensor is able to directly discriminate 18 different colors and access color components. Here is a table with the color numbers provided by the sensors: Dark room, color sensor perpendicular to the plates.
The first test was performed in a dark room, with the color sensor perpendicular to the plates. Test distance between base of the sensor and the plates is 1, 2, 3, 5 and 8 studs. At 3 studs distance, green is seen as black. At 5 and 8 studs, all colors are seen as black. With this setup, HiTechnic sensor returns rather weird data, with - for example - black seen as white!
The scripts can then directly be transferred to a Lego Mindstorms NXT robot, to see the result in real life. The resulting NXT programs have the compactness and clarity offered by that programming environment.
More information found at:. It relies on a dedicated run-time kernel based on the Ravenscar profile , the same used on the Goce satellite: It also has a component architecture UObject for distribution. Urbi is compatible with many robots, including Nao cf Robocup , Bioloid or Aibo.
It uses NXT-G and. It is unknown if you can legally implement this in FLL competitions. Ruby-nxt is a library to program the NXT for the Ruby programming language. Unlike the other languages for the NXT, the code is not compiled to a binary file. Instead the code is directly transmitted to the NXT via a Bluetooth connection. It supports direct commands, messages and many sensors also unofficial. It has also support for a simple message-based control of a NXT brick via remotely executed program basic NXC code included.
Windows support is also possible with the win32 port of libusb. The library allows users to control a Lego NXT via bluetooth controller from within other C programs. The library provides low level control and high level abstraction. It supports direct commands and several aftermarket sensors. Physical Etoys is a visual programming system for different electronic devices. It supports direct mode and compiled mode.
The sensors come assembled and programmed. In the software see Programming above , people can decide what to do with the information that comes from the sensors, such as programming the robot move forward until it touches something. Lego also sells an adapter to the Vernier sensor product line. Vernier produces data collection devices and related software for use in education.
Sensors are connected to the NXT brick using a 6-position modular connector that features both analog and digital interfaces. The analog interface is backward-compatible using an adapter with the older Robotics Invention System.
The digital interface is capable of both I 2 C and RS communication. Lego Mindstorms NXT 2. More information found at:.
