Cellphone operated robot

cell_bot

If you can get through the cell phone text speak, you’ll probably enjoy this cool tutorial on how to build a cell phone controlled robot. This bot decodes the key tones, similar to the automated phone systems we’ve all experienced. It uses a chip called a MT8870 DTMF decoder to translate the signal for the Atmega 16 controller. The circuit diagram is pretty hard to read, maybe we missed a downloadable one somewhere. The source code is available.

It would be nice to get some feedback from the robot, so you aren’t driving it completely blind. This is similar to the Lego cell phone rover that we showed you before.  Next, he should make it recognize voice commands.

    nice! I’ve used java application which changed the display color and a photoresistor to send commands to the mcu :-)

    Here I thought road SIDE bombs were bad.
    Now it can be road driven and cell phone activated IEDs.

    Is it me or is instructibles.com having some issues?

    I am getting all the time:
    ERROR 500: javax.servlet.jsp.JspException: ServletException in ‘/common/newlayout.jspx': Can’t insert page ‘/pages/explore/newrightbar.jsp’ : ISO-8859-10

    @k

    im pretty sure a guy who’s life’s ambition involves blowing himself up someday isnt gonna even know how to use a soldering iron.

    most ied’s are just a bunch of construction grade explosive or an old military shell with two wire jammed into the contacts for the vibrate motor on a cellphone.

    I’m also developing an DTMF robot…

    development on this site: http://oscar.crf.nu/
    //in swedich.. but you can look at the pictures…

    I’m using a 3G phone to get video feedback… and I have a serial connection between the phone and an arduino to auto answer and turn on the phone flash light, etc…

    I have only on big problem… the communication cable always breaks (because of low quality wires :( ).. so I’m considering only using a headset for the DTMF tones and skip the datacommunication..

    Nice to see someone else doing a simular project. :)

    Very very interesting !
    I’ve been walking around with this idea a long time, but am not (yet) technical enough to get it to work.

    My idea for the robot was:
    – make it run on a solar panel
    – make a video call to the robot
    – let it auto-pickup
    – drive it into Area 51 :-)

    Perhaps I just need to read the articles and go figure this out ! (-:
