Operation Neko Hunter

[IvanGrozny2012]

Hey all, this is my first project and I admit it sounds rather ambitious, but here are the things I hope to incorporate into a single robot:
2 SHARP IR rangefinders (general distance left/right)
1 PING sensor (distance forward)
1 ColorPAL (for spotting and tracking specific objects)
1 Temp sensor (for spotting and tracking specific living creatures)
1 Sound Sensor (basic sound = action activities)
1 LCD screen shield (Visual output of target analysis)

I am using the 4WD DFrobot plaform with the DFRduino Romeo board.  So far I have successfully soldered (for the first time lol) everything together, thanks to the helpful videos posted.  I have power and wheel/motor movement and good board telemetry, now I am moving to the actual sensors and programming it all and starting from the beginning.

I have not had much success in finding help with the SHARP IR sensors however, so I am hoping someone on here can help me out a bit.  I have seen wiring schematics but not for Romeo and nothing really for getting it to work with the board. 

My other question is: how do I use the sensors attached on the rear motors as well?  It would seem that they are involved with some sort of timing wheel but in the videos and PDFs they dont even mention them....

STAGE 1: Assemble chassis and solder all wiring as needed
STAGE 2: Attach board and wiring, attain telemetry and power
STAGE 3: Get IR rangefinders working
STAGE 4: Get Ping Sensor working and attain some degree of movement based on distance
STAGE 5: Get Color sensor to detect items and pass data to LCD shield
STAGE 6: Integrate all attached sensors to seek out by color and move based on surroundings
STAGE 7: Get Temp and Sound data to register, have data somehow compile into a database
STAGE 8: Figure out a way to have actions based on data of surroundings

Thanks in advance!

Hi,

Sharp ir rangefinder seems to simply output voltage in a range of 0.5-2.5 V. You need to plug it to analog in port.

If you're not familiar with analog input -things, you might want to read these arduino examples. In these they just use potentiometer and Light-resistive diode to control led blink rate, but rangefinder controlling more complicated logical system works basically the same way.

Analog Input Just the wiring. 5V operating voltage is good for this rangefinder, too.

Calibration You want to calibrate the sensor too, because it's not 0-5V as potentiometer would be, it's 0.5-2.5V.

And yep, they are arduino examples, board looks different and is blue, but all the ports are the same.
Hope this get's you a bit further

Hi,


I'm not sure if you are reffering to the motor encoders?


Here is an example: Motor Encoders wiki


Have you seen the wiki for the IR sensors? I'm not sure which IR sensor you are using, but this might be a good starting point. IR Sensor Wiki
