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.

I want to link a certain grey to an absolute value of the light dependent sensors. 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:.

Turn After that I wrote a small program that turns the Asuro robot degrees. I placed a piece of isolation tape on the circuit board and the problem is solved. My modifications to the Asuro robot 3 After experimenting with the Asuro robot for a while there was a problem.

The solution is to make a small circuit that enables the switching voltage regulator only if the input voltage is higher than 4.

Replacing the ATmega8 The ATmega8 that comes with the Asuro robot uses an undocumented asur to upload programs and is locked so you can’t change it, meaning you couldn’t use Arduino to upload programs to it. Fortunately, you can use the ATmega8 from any Arduino board instead. Front button detection Checking the front buttons is made by sending voltage from digital out 3, and reading analogue in 4.

The robot comes as a kit and has the following features: I also made a second battery-pack with four rechargeable AA batteries that have a capacity of mAh.

My modifications to the Asuro robot 2 Line follow sensor: Asuri After that I wrote a small program that sends the value of the line follow sensor on the Asuro robot to the PC. Odometer sensors and line following sensors are now read continuously and the values of the sensors are continuously available as global variables. For the flashing I use the Windows version of the flash program via Wine.

This means you need more batteries to compensate for the extra 2 Volts, and the efficiency of these voltage regulators is not great. A small correction in the function Go solved this problem: My rechargeable AAA batteries have a capacity of mAh. 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.

I did two measurements, one normal and one when the Asuro robot was covered with two hands. 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.

You need to solder a couple of extra wires onto the Asuro to program it. The odometer counters are also continuously updated and are also available as global variables.

The locking system is made from a screw terminal. De distance between the shroud and the surface is minimal about 0,5 mm and that’s why the surrounding light has no more influence. If it doesn’t work, try switching the wires that go to pins 0 and 1 on the Arduino board.

I wrote a small program that makes the Asuro robot drive forwards for mm.

This Asuro wiki in German has more information. The extra switch is necessary because the switching voltage regulator is always working, and will drain the battery.

I use Genie for writing the programs. 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 asurk may want to make a backup of the original file first: The result of this modification is a stable measurement from the odometer sensors that are comparable with the measurements with 0 mm distance.

But I also want to asuo a crossroad. An extra advantage is that the isolation tape is much less slippery and the motor stays on its place much better. Board Setup and Configuration.
