i think that one is line following robot command, i need sumo robot command. can i use http://www.societyofrobots.com/downloads/stampy_sumo_source_code.zip to program atmega168 with avr studio?

can i replace the icsp header with a serial port ? i do not have a iscp header!!!! how to add serial port to the circuit in http://www.societyofrobots.com/step_by_step_robot_step3C.shtml?
Pls reply, reply the above question too!!!!

FYI, my Stampy sourcecode is for a PIC16F877 and not for AVR.

You will need to send serial data from the UART (tx and rx on your AVR). Then connect those to pins to a rs232 to serial adaptor (about ~$6). Just search this forum and google for those terms.

If I ever get my SparkFun parts in (they seem to be having serious shipping issues lately) Ill write a tutorial for this using AVR.

Hey Admin, did you ever bother to get one of the Arduinos from them to check out? It's pretty nice for someone just staring out to get the feel of MCU's, and it's nice for people like me who don't have time to mess around with building their own prototyping board, and buying dongles and such.

Admin · « **Reply #7 on:** July 11, 2007, 09:19:14 PM »

Nope, but the specs looked good to me.

i solve the problem about icsp header by buying AVRISP AVR IN -SYSTEM PROGRAMMER http://www.rsmalaysia.com/cgi-bin/bv/rswww/searchBrowseAction.do?N=0&Ntk=I18NRSStockNumber&Ntt=4725933&Nty=1&D=4725933&callingPage=/order/OrderHistoryView.jsp&BV_SessionID=@@@@0535305059.1184232628@@@@&BV_EngineID=ccccaddlgkglfkhcefeceeldgondhgm.0&cacheID=mynetscape&Nr=avl:my , will it work?
i hope admin can upload the code for atmega in one week time, please... send an e-mail to notify me after you upload it.

You can find my Stampy code for AVR here:

As for the code for serial, count on it taking me weeks not days to post it

newbie · « **Reply #11 on:** July 13, 2007, 06:10:04 AM »

can i use the above command which you gave with my board http://www.societyofrobots.com/step_by_step_robot_step3B.shtml, i replaced the microprocessor in that board with atmega168. Can it has 100% same function like stampy ?

i really need it, the competition is coming very soon in 2 weeks !!!!!!!
really thank you.

Admin · « **Reply #12 on:** July 13, 2007, 10:24:41 AM »

You need to make a few small changes in your code, but yes it will work.

Follow the instructions here:

newbie · « **Reply #13 on:** July 14, 2007, 05:52:15 AM »

should i change the atmega 8 option into atmega 168 if i am using atmega 168

does the command included a command which do not let the sumo robot came out from the battle ring

?
if no, how to add it ? i will use a photoresistor to detect the outer line.
does the command include a command which let the ir sensor rotate

?

if i want to add some command, which place should i add to?
At which point should i plug the ir sensor, servo motor (for ir), servo motors and photoresistors ?
i really a newbie, really thank you for everybody support !!!! thank you!!!! you guys are great!!!!!!!!

yes

the algorithm makes your robot only go to the opposing robot. there will never be a cliff between your robot and the opposing robot. therefore you do not need to ever detect a line

Quote

just command the servo to rotate just like you do for the wheels. all my code is well commented and should be self explanatory.

so, the robot will not move when it does not detect opponent? or after finishing rotate the ir sensor (servo motor) without any opponent detected, it will turn round like stampy? i want it to turn round like stampy, what should i add?

i want to add four photoresistors at the side of the robot to prevent it from going out when it push the opponent out from the battle ring and when opponent want to push it out of the battle ring, what should i add?

newbie · « **Reply #16 on:** July 15, 2007, 05:32:38 AM »

this is my algorithm for the four photoresisitor with leds like mobot:

if sensor1 on the balck line, while other sensor on white surface, robot will turn right.
if sensor3 on the balck line, while other sensor on white surface, robot will turn right.
if sensor1&3 on the balck line, while other sensor on white surface, robot will turn right.
if sensor2 on the balck line, while other sensor on white surface, robot will turn left.
if sensor4 on the balck line, while other sensor on white surface, robot will turn left.
if sensor2&4 on the balck line, while other sensor on white surface, robot will turn left.
if sensor1&2(front) on the balck line, while other sensor on white surface, robot will turn right.
if sensor3&4(back) on the balck line, while other sensor on white surface, robot will move forward as usual.

when all the sensor on white line, the robot will function as usual.

The answers to all your questions are in the tutorial.

"Algorithm
The algorithm takes data from a scanning Sharp IR Rangefinder, and uses edge detection to decide where to drive. If no target is available, it would go into a search mode and spin clockwise. Otherwise, it would attempt to drive towards the left side of the opposing robot."

Again, this is not necessary. With the Stampy algorithm, your robot will only drive towards the opposing robot, not over the table. The table does not end between your robot and the other robot, therefore it will never go over the table.

i knew the robot will not goes off from the table (battle ring), but it will go off from the battle ring when the opponent push when it is in a spin mode or when it cannot detect the opponent. $:-\$ ! the robot which went off from the ring will be qualified as loser although without any pushing from the opponents. i scare my robot will lose without reason. below show 1 condition where my robot will went off from the battle ring.

(the arrow show the heading / front part of the robots.)

hi sheng fatt,
so you are suggesting adding photoresistors to the bottom of your robot so it can detect when it has reached the line and try to avoid being pushed over.
yes, that should work.
obviously you will need to modify the circuit to add the sensors and modify the program to monitor the sensors and take evasive action.

if you want people on this forum to design and write the changes for you then i'm afraid you are out of luck.
we are mostly too busy working on our own robots.

dunk.

i tried my self on the programming, however i face a problem,
are there any code to represent equal to "=" ?

hazzer123 · « **Reply #24 on:** July 19, 2007, 03:09:56 AM »

AFAIK, the "=" operator is an assignment operator and is used exclusively to assign the variable on the right with a value. If you are doing comparisons, like in an IF statement for eg, the you use the "==" operator which is used to compare values.

And dont PM me either please with questions. If you have them, post them in the forum. then everybody can benefit from the answers.

do you have any schematic circuit, i do not want the graphical circuit, http://www.societyofrobots.com/step_by_step_robot_step3B.shtml,
can i connect a normal motor to this board? where should i plug in?

Ummmm no . . . but if you just draw lines between the color dots, that would be what you want . . . seriously, the circuit is so simple it doessnt require a traditional schematic . . . just plug and play.

Nope. You will need a motor driver first. Search the forum for this, many people have asked in the past . . . The advantage of a servo is that it has a motor driver already built in, along with gears and feedback control as well.

newbie · « **Reply #27 on:** July 25, 2007, 02:21:40 AM »

so, we need to use a servo motor although for the wheel?

Admin · « **Reply #28 on:** July 25, 2007, 04:31:16 AM »

I dont understand your question . . .

For those who dont know what they are doing, I suggest using servos for your first bot . . .
