Solar Tracker uses LEGO

Solar Tracker make by LEGO
LEGO® Solar Tracker bygget i et elektronik projekt. 4 lysdioder generer en spænding når de belyses. motorer vender platformen så de fire dioder belyses lige meget.



SolarRobot
A Robot that tracks the movement of the sun in order to optimize the Position of a Solar Panel. The Robot uses a Lego RCX controller, with Lejos firmware installed. It runs custom Java code



NXT Solar Tracker
A rotating solar tracker. A Vernier Differential Voltage Probe and NXT are used to measure the voltage generated by a pair of solar cells when in the presence of the sun or a strong light source.

Sun Tracker Project


Intelligent Sun-Tracking System for Efficiency Maximization of Photovoltaic Energy Production
Abstract.
This paper focuses on the optimization of the electric energy production by photovoltaic cells through the development of an intelligent sun-tracking system. The developed tracking system is innovative in relation to the usual sun tracking systems available in the market. In fact, the developed solution has many advantages in relation to similar existing devices, as this system is autonomous regarding the information needed to process the optimal orientation and is intelligent in a way that it performs on-line monitoring of the photovoltaic energy production.

An experimental prototype was built and field results have proven the good performance of the developed tracking system.Overall System Presentation
The overall system is presented in fig. 1. The complete
strategy is composed by 5 sub-systems: 1) Electro-
Mechanical Structure; 2) Control Unit; 3) Supervisory
System; 4) Wind-meter; 5) Photovoltaic Park.





Sunlight Tracker Project
Automated sunlight tracker with an intelligent algorithm using sensors  



BOT01 Initial Test
This is the first prototype of a sun tracker project BOT that I just through together off the top of my head. Completely hand made from recycled scrap and parts. Arduino controller with a Motor Shield.

Sun Tracker Working



Sun Tracker
We set out to build a solar tracker.
The tracker uses two Nema 23 bipolar stepper motors to rotate 2 photovoltaic cells around the altitude and azimuth axes. We have three tracking algorithms to track the sun. The first moves the PV panel in little squares in spherical coordinates, finds the point on the square with the best voltage, and moves there, then starts over. The second moves in a little square, finds the voltage gradient, and uses that to decide where to move. The third uses the second strategy to find 5 or 6 good points spread 1hour apart, uses a multivariable, nonlinear, least-squares fit to find its latitude, the day of the year, the time of day, and then predicts where the sun will be next. It will use this equation for a few repositions, and then check to make sure it’s right using the second algorithm. In moving the PV panel, our stepper motors ramp up to speed in order to prevent overshoot and jerk/rattling.



Sun Tracker Working Video
We built this little prototype as part of an embedded systems class I was taking Fall of 2008. The green pcb board mounted on the plastic "table" was harvested from an old optical mouse.

Easy Make Sun Tracker by LEGO



Easy and Simple Homemade Sun Tracker Video
Using no sensors, no circuits, no transistors or fotoresistors, this home made "Lego Sun Tracker" located the sun withour any problem.


Sun Tracker Robot Timelapse
FINALLY, I had all the parts to make both the Sun Tracker and the CamBot, PLUS we had a (somewhat) sunny day. This is about 7 hours of runtime with pictures taken at 60 second intervals.
