Hallo und willkommen auf meiner Seite!!!1!1!11
Was ich so mache
- Ich bastele gelegentlich an Robotern, siehe unten
- Ich programmiere manchmal Animationen für die Borgs
- Alle farbigen Borgs haben Plasmaeffekte von mir :-)
- Ich habe an der rfm12lib, dem rfm12usb und dem rfm12 Bootloader mitgebastelt..
ausserdem benutze ich rfm12s in meinen Projekten - Ich bringe Design in das Wiki!
- Ich habe schon mal ein Kind gelötet...
- Manchmal helfe ich bei der Labortage Orga
- Ich pflege die Sourcecodes des CAN-Gateway und des Cand
- Ich habe eine experimentelle Steuerung für die Lernroboterarme im Labor gebaut..
.. aber nirgends dokumentiert, keinen source hochgeladen und die Platine mit handschriftlichem Schaltplan zuhause.. shame on me ^^ - .. äh, das gleiche gillt für einen Tschibo Staubsaugerroboter... damnit, I see a pattern here...

Rechts sieht man mein aktuelles Roboterprojekt, den Shr0dBot.
Vielen Dank an Mati für das Foto!

Das habe ich mal gemalt, als ich die bunte Kreide fand.

==== MOTORCTRL ATMEGA8 PIN CONFIGURATION ==== Names in () are or were planned. Pins marked with [in] are inputs, whilst the ones marked with [out] are outputs. All other pins make use of their respective special function(s). ** GENERIC XTAL1,2 - 16MHZ, no capacitors VCC, AVCC - +5V, 100nF GND - COMMON GROUND ** PORT B 0 - VACCUUM CLEANER DRIVE ON/OFF [out] 1 - PWM MOTOR 1 [OC1A] 2 - ISP [SPI SS], PWM MOTOR 2 [OC1B] 3 - ISP [SPI MOSI], WHEEL/MOTOR 1 LIFTOFF DETECTOR [in, int. pullup] 4 - ISP [SPI MISO], WHEEL/MOTOR 2 LIFTOFF DETECTOR [in, int. pullup] 5 - ISP [SPI SCK], FRONT LIFTOFF DETECTOR [in, int. pullup] 6 - XTAL1 7 - XTAL2 ** PORT C 0 - BATTERY POWER DIVIDER (1nF load) [ADC0] 1 - MOTOR 1 CURRENT MEASUREMENT (capacitive load?) [ADC1] 2 - MOTOR 2 CURRENT MEASUREMENT (capacitive load?) [ADC2] 3 - ACCU LOADER ON/OFF [out] 4 - TWI SLAVE [SDA] 5 - TWI SLAVE [SCL] 6 - RESET ** PORT D 0 - MOTOR 2 FORWARD [out] 1 - MOTOR 2 REVERSE [out] 2 - ENCODER A [in] 3 - ENCODER B [in] 4 - MOTOR 1 FORWARD [out] 5 - MOTOR 1 REVERSE [out] 6 - BRUSH DRIVE 1 ON/OFF [out] 7 - BRUSH DRIVE 2 ON/OFF [out] ** FREE PD6, PD7 ==== MOTORCTRL MISC STUFF ==== * Encoder IR-Diodes 1k ?? (re-evaluate) * How to connect phototransistors? I can remeber they had 1k resistors on em. (See on orig. board) * Use 1/8th Voltage divider (14.4 / 8 = 1.6V -> 12 cells * 1.5V max = 18V -> 18/8 = 2,25V) * Use logic level fets for vacuum and brush motor turnon/off * Reverse engineer loader circuit, reuse relais if it could cut loader power * Use L6202 motor driver ICs * Motor current: ** Blocked motor draws max. ~800mA ** Normal operation ~350mA ** 0.1 ohm current sense resistors ** Max ~80mV sense voltage ** ~35mV in normal operation ** 25 times amplification to use with adc @ 2.56V internal reference ** Use lm358 opamp * What do the two diodes @ current sense / gnd do? * atmega input with pullup -> encoder phototransistors -> 4,7k -> gnd They used: * L289 for motor control * 14.4V motor power * LM2565T switching power supply for logic * IR-led + phototransistor for encoders ** 14.4V+1K for leds ** ~2.3V / 11mA for leds ** Try 220ohm @ 5V (should be around 12-13mA) ** Phototransistors are pulled up by 10k or something (one has 10k, one has something else) ==== MAINBOARD SPECS ==== * Use the fat 128k flash / 16k ram 40pin DIP Atmega * Probably use a switched power supply -> ask peter for that chip * Think of creative use for the big fat atmel * Use rfm12
Hansinator's MotorCTRL Board
- Both L6202 are correctly connected to motor and atmega
- Need a solution for current sensing
svn notizen
someday this needs to be patched to use crc and stuff, as in trunk ./src-atmel/automatization2.0/cand/branch/usb_support/ ask sören about branch -> delete ./src-host/src/cand-ucspi_tcp/config.h:8:#define UART_HOST ask peter which source is for moodbar (src-atmel/theke or src-atmel/moodbar) -> one is crap, the other doesn't work... ask peter about ruby lapd
bash the sources
# grep for stuff
grep -Hirn UART_HOST . | grep config | grep -v svn > uarthost.txt
# print all files in uarthost.txt (grep output)
for i in $( gawk -F : '{ print $1 }' uarthost.txt ); do echo $i; done
# remove all occurences of uart host define in files
for i in $( gawk -F : '{ print $1 }' uarthost.txt ); do sed -e '/#define UART_HOST/d' < $i > $i.new; done
for i in $( gawk -F : '{ print $1 }' uarthost.txt ); do mv $i.new $i; done
# revert files...
for i in $( gawk -F : '{ print $1 }' uarthost.txt ); do svn revert $i; done
