 this is my first time posting a robot. i've build 4 robots in my past. this is another project for me to learn more about writing in code. its all practice and preperation for my never ending project. a autonomous octopod. so fell free to tell me if im doing somethn wrong or if there is a better way to going about it. all coments good and bad are welcomed.. just need a few outside openions.i basically built a mintduino and put it on a pcb. im using two 9v batteries. one for the brains and sensors, and one for motors and servoes. i dont know the actual cost of build due to the fact that 85% of the stuff i already had. NOTE: the high and lows used for the continuous servoes are based on what works for my modified servoes. you may have to play around with numbers a bit to figure it out for your servoes. center and sweep are for standard servoes. i decited to redo my motor/ servo drive unit. i can now run 9v for my motors and 5v for my servoes on the same little shield using the same battery. will post pics of the new MDU later on.

im having trouble with it programming, so im going to double check everything. but its been on hold due to all the snow we have been getting.

my controller is a mintduino sodered to a protyping pcb. everything is hooked up corectly.. ive double checked about a thousand times using different sources js to verify other sorces. im using the FTDI BASIC from sparkfun to try to program it. i keep getting " avrdude: stk500_getsync(): not in sync: resp=0x00 ". i held the shift key and then uploaded to try to get a diognostic and it says " avrdude: usbdev_open(): did not find any USB device "usb" ". ive tryed every borde on the program and every port on my computer. ive tryed updating driver to every driver the arduino program has in the folder. ive tryed another ATMEGA32 chip and it does the same thing. both have the bootloader because when i power it up and press reset, the pin 13 led lights up and blinks fast for both then goes out after about a second. when i try to load a program the TX light on the FTDI BASIC blinks, but the RX light never does. ive tryed the hold the reset button then upload. and that doesnt work either. but if i plug in my arduino micro it works fine without a glitch. so im STUMPED!!!!! idk what to do from here besides to js go buy me a new arduino borde. but that is absolute last resort. can someone PLEASE help!!!!!!!!!!

Have you read and tried what is suggests here?

yup... didnt work.. and i tried a loop back test and both light ligh up then...

I loved the track layout.

new updated pics and i will soon put up a video dealing with testing... comming alone fast.. just waiting on my IR sensor so i can start on the final programming.

Steve... :|

idk..... that name js came to me....lol... i really dont know why....

kariloy's picture

...and also I must say that my Steve's name... also came to me... it just felt right (at least after all the complaints of the people who couldn't spell its original name :| )

Anyhow, nice build that you have going on there :)

i was looking around at different bots on lmr and js realized that u had the first steve.. sry bout that... i honestly didnt know..

I appreciate the respect, but you can also call it Steve as far I'm concerned. One thing though, it must never be bereft of pants!

I just couldn't disappoint the shoutbox audiences :P Carry on, as you will! :)
