Parallax Laser Range Finder

This is a little bot I made using a pre-release PropBOE board, the newly released Li-Ion Power Pack/Charger board, and the Parallax Laser Range Finder designed by Grand Idea Studio. The music in this video is by tymkrs, visit them at www.tymkrs.com

Parallax Laser Range Finder

Designed in conjunction with Grand Idea Studio, the Parallax Laser Range Finder (LRF) Module is a distance-measuring instrument that uses laser technology to calculate the distance to a targeted object. The design uses a Propeller processor, CMOS camera, and laser diode to create a low-cost laser range finder. Distance to a targeted object is calculated by optical triangulation using simple trigonometry between the centroid of laser light, camera, and object. Features: Compact module with integrated CMOS camera and laser system Optimal measurement range of 6–48 inches (15–122 cm) with an accuracy error <5%, average 3% Maximum object detection distance of ~8 feet (2.4 meters) Range finding sample rate of 1Hz Single row, 4-pin, 0.1” header for easy connection to a host system Application Ideas: Distance or liquid level measurements Object detection and/or avoidance Item counting Key Specifications: Power requirements: 5 VDC @ 150 mA Communication: Asynchronous serial; 300–115,200 baud with automatic baud rate detection Dimensions: 3.95 x 1.55 x 0.67 in (10.05 x 3.95 x 1.7 cm) Operating temperature: +32 to 122 °F (0 to +50 °C) Alternate Views: Click for Close-Up 使用說明書: http://www.parallax.com/portals/0/downloads/docs/prod/sens/28044-LaserRangeFinder-v1.0.pdf Parallax 論壇 http://forums.parallax.com/ 學習資源 http://www.playrobot.com/cart/shop.php?html=action&Fid=10031&Tsubject= http://www.parallax.com/Store/Sensors/AllSensors/tabid/760/ProductID/774/List/0/Default.aspx?SortField=ProductName,ProductName
