PureBasic und Buggy mit Webcam Teil 2

Verfasst: 07.10.2007 16:18

Hallo Leute,

die nächste Erweiterung ist erreicht:

2x digitale Eingänge (Taster)
8x Port Erweiterung als Ausgang
1x LDR mit AD Wandlung von 10 bit
1x MIC mit AD Wandlung von 10 bit
1 x Motorsteuerung mit zwei Motoren

Auf dem Buggy habe ich eine Webcam montiert. Derzeit verwende ich zwei USB Kabel. Sinnvoll ist hierbei aber eine leichtes USB Kabel selberlöten (benötigt nur 4 Adern) ein kleiner USB Hub noch auf den Buggy montiert und den Buggy und die Webcam daran anschließen. Wer es möchte kann es auch mit einem Funk USB Hub betreiben. Dann ist man "wirklich" unabhängig.

Jetzt beschäftige ich mich erst einmal mit der Übertragung von Daten per Internet inclusive WebCam streaming. Hilfe nehme ich gerne entgegen...

Habt Spaß :allright:
Michael

mensch kauf dir eine farb-funk-cam, die ist halb so groß, bekommst du schon für 45 euro. habe ich auf meinen robby(2x atmega32) und steuere ihn auch mit einer selbsterstellten gui in purebasic. die datenauswertung der hindernisse macht purebasic und dann sende ich über funk serielle daten zum robby zum reagieren. die serielle schnittstelle funkt mir auch alle motordaten zum pc usw.

ich komme ganz ohne firmenware aus, alles selbst geschrieben mit bascom für den mega.

Hi,

erst einmal freu ich mich das auch andere sich mit dem Thema Robotik beschäftigen. Warum ich hier diese Sachen veröffendliche ist der Wunsch das auch "nicht Elektroniker" diese Technik nachvollziehen können und/oder einfach nachbauen.

Deine Idee mit der Funkkamera ist gut. Du kannst doch mal ein Produkt als Beipiel nennen und schildern wie Du die Wandlung an dem PC (Analog Video in digitales Video PC Signal) vornimmst. Sicherlich einfacher als über ein TV Karte ?!? Deine Datenauswertung der Kamerasignale ist eine weitere wichtige Sache. Zeig uns doch einmal ein Beispiel wie Du dieDatenauswertung der Hindernisse vornimmst. Ich nehme dann gerne die Anpassung an den Buggy vor. Vielleicht hat der Eine oder Andere auch Ideen die er beisteuern möchte...

Gruß Michael

ich lese ein funkvideobild mit capture ein und dann kann ich mich mit purebasic austoben und etwas schreiben, wo man denn meint, welche pixeldaten man in dem purebasicsreen auswerten soll. da gibe es verschiedene kunstgriffe.
