He uses the RC GH-2's standard RC equipment along with an onboard electronic compass and a radio datalink to a remote PC. Very impressive! <br><img src="pete.grayHB_Prot_Constr1.jpg" height=250><br><br> See <a href="http://home.comcast.net/~pete.gray/embedded.htm" onclick="window.open(this.href,'newWindow'); return false;" > Pete Gray's Embedded Systems Page</a> for more details.<br> <hr> <br> Dr. Guangming Zhang from the University of Maryland at College Park sent in these images of a robotic hovercraft project undertaken by Jeffery Schleigh, a student working with Dr. Zhang. Jeff Schleigh and his collaborators integrated a LEGO Mindstorms Robotics Invention Kit with a GH-C kit. The LEGO onboard computer controls two thrust motors for differential thrust. Sensors allow the computer to follow a track on the floor. The LEGO system opens up a lot of possibilities for future robotic hovercraft projects! <br> <img src="zhang-1-robotic-hovercraft.jpg" height=250> <img src="zhang-2-robotic-hovercraft-sm-h.jpg" height=250> <br> <img src="zhang-3-robotic-hovercraft.jpg" height=250> <img src="zhang-4-robotic-hovercraft.jpg" height=250> <br> <img src="zhang-5-robotic-hovercraft-sm-m.jpg" height=250> <img src="zhang-6-robotic-hovercraft.jpg" height=250> <br> <br> See Jeff Sleigh's detailed tech report for more information: <a href="http://techreports.isr.umd.edu/ARCHIVE/dsp_details.php?isrNum=5&year=2006&type=UG¢er=ISR" "onclick="window.open(this.href,'newWindow'); return false;">Construction Of A Hovercraft Model And Control Of Its Motion </a><br> <br><br> <hr> <br> Brian Sardo and Vikas Mundada built the computer controlled hovercraft pictured below as part of their Masters Project at Boston University. They purchased Goldstein Hovercraft ducts and motors at our educational discount rate, and then designed the hovercraft and its electronics themselves. Their hovercraft was not autonomous, but it used some pretty fancy control circuits. <br> <img src="garbri1.jpg" height=250> <img src="garbri2.jpg" height=250> <img src="garbri3.jpg" height=250> <br>Vikas and Brian shared their <a href="./garbri-text.html"onclick="window.open(this.href,'newWindow'); return false;">writeup</a>, which focuses on the electronic aspects of the project. <hr><br> Notes for building a robotic hovercraft using GH parts: payloads up to 1.5 lbs will be fine on smooth floors. Up to 2.5 lbs payload is workable with difficulty. Payloads can be increased by using Power Upgrade motors, extra large foam hulls, and skirts, all of which we can provide. Payload can be further increased by using li-poly batteries (which you can provide).
