ASURO ROBOT PDF
Here you can find the detailed ARX ASURO Documentation and Datasheets of the parts used on ARX ASURO. You will need the Acrobat Reader to view these. The ATmega8 that comes with the Asuro robot uses an undocumented protocol to upload programs and is locked so you can’t change it, meaning you couldn’t. Learn more about Asuro Robot.

My modifications to the Asuro robot 6 The electronics of the Asuro robot are powered by a battery. The line follow sensor is a light source that shines its light downwards and two light dependent sensors that receive the reflected light from the surface.
I placed a piece of isolation tape on the circuit board and the problem is solved. Sources for Electronic Parts.
This because the supplied Linux version is no longer usable on a modern Linux system due to its age. Turn the Asuro robot on just before pressing the upload button in the Arduino environment. Changing Arduino Preferences Since the Asuro robot runs at half the speed of the Arduino board 8 MHz instead of 16 MHzyou’ll need to change a couple of files in your Arduino preferences file you may want to make a backup of the original file first: But there is a small problem, when the input voltage is between 2.
I built a small shroud around the line follow sensor. My modifications to the Asuro robot 1 After assembling the Asuro robot I have tested the sensors. Then I took a small connector 3 pins from an old PC and connected that to the original battery pack. The major differences are: A solution is to use a voltage regulator. The cover is made of cardboard. LineData After that I wrote a small program that sends the value of the line follow sensor on the Asuro robot to the PC.

A better solution is to use a switching voltage regulator. Checkout the Asurino page for further information. I decided to make a personal Asuro library based on the Asuro library v2. Fortunately, you can use the ATmega8 from any Arduino board instead. Since the Asuro robot runs at half the speed of the Arduino board 8 MHz instead of 16 MHzyou’ll need to change a couple of files in your Arduino preferences file you may want to make a backup of the original file first:.
Strange things happened during the execution of a program, and also the program stopped for an unexplained reason. A small correction in the function Go solved this problem: A small correction in the function Turn now takes care of a correct turn: My conclusion is that rbot metal cover of the motor caused a short-circuit on the circuit board.

I want to link a certain grey to an absolute value of the light dependent sensors. I have changed the standard value of 61 to I moved the four axles of the Asuro robot 3 mm to the outside to make space for a locking system on the axles that have the gear with the odometer reflection sticker.
Pop the ATmega8 out of an Arduino board and place it in the Asuro make sure it’s the right way around. Fobot ATmega8 that comes with the Asuro robot uses an undocumented protocol to upload programs and is locked so you can’t change it, asuuro you couldn’t use Arduino to upload programs to it. Because the ATmega8 is in the Asuro, not the Arduino board, you need to use the switch on the robot instead of the reset button on the board.
Front button detection Checking the front buttons is made by sending voltage from digital out 3, and reading analogue in 4. Every 1 ms one of the four sensors is read, asuor after every 4 ms all the sensor values are refreshed. This means that the odometer system is not very reliable when following a line.
The connector on the Asuro robot has an extra pin that prevents that the connector from the battery-pack is connected in the wrong way. Connect the USB cable to the Arduino board and the computer.

An extra advantage is that the isolation tape is much less slippery and the motor stays on its place much better. If you use the line following sensor to detect colours they also are less reliable if the voltage is not stable. The odometer sensors are less reliable when the voltage is low.
