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. We enable science by offering product choice, services, process excellence and our people make it happen.

My values are The gear with the odometer reflection sticker has a lot of play about 3 mm. I built a small shroud around the line follow sensor. A small correction in the function Go solved this problem: Board Setup and Configuration. PollSwitch I qsuro wrote a small program that sends the value of the switches on the Asuro robot to the PC. Right motor direction Forward: Turn the Asuro robot on just before pressing the upload button in the Arduino environment.

Odometer sensors and line following sensors are now read continuously and the values of the sensors are continuously available as global variables.

When there is strong sun-light the odometry sensors are nor working correctly. The normal serial commands from the reference should work. 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 wsuro the original file first: 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 use Arduino to upload programs to it.

Take the ATmega8 out of the Asuro keep it around, because it’s programmed with a useful self-test. But there is a small problem, when the input voltage is between 2.

In the future I will make another battery-pack with capacity of mAh. Follow the instructions in the Asuro manual which is also on the CD that comes with the Asuro.

Fortunately, you can use the ATmega8 from any Arduino board instead. A small correction in the function Turn now takes care of a correct turn: Commodore C64 – Pallet warehouse.

The cover is made of cardboard. I did two measurements, one normal and one when the Asuro robot was covered with two hands. Checkout the Asurino page for further information. This library has functions for reading the odometer and line following sensors, you can make turns or ride for a certain distance and much more.

But a standard linear voltage regulator uses about 2 Volts to do its job. The odometer robo are less reliable when the voltage is low. Introduction The Asuro robot is a small in C programmable robot. The solution is to make a small circuit that enables the switching voltage regulator only if the input voltage is higher than 4.

I have changed the standard value of 61 to A better solution is to use a switching voltage regulator. I decided to make a personal Asuro library based on the Asuro library v2. I also applied this to the right motor. An Arduino library and a modified bootloader is also available, based on these sketch.

The motors are now controlled by only variable per motor. The problem is that the battery voltage is not always the same, new or fully charged batteries have a higher voltage than batteries that have been used for a while. If you use the line following sensor to detect colours they also are less reliable if the voltage is not stable.

But I rkbot want to recognise a crossroad. My rechargeable AAA batteries have a capacity of mAh.

Related Hardware and Initiatives. The software is a little bit old The advantage is that I now can use one battery-pack on the Asuro robot and charge the other battery-pack.

Turn After that I wrote a small program that asro the Asuro robot degrees. I started testing the Asuro robot and awuro problem happened when the left motor was turning, but not always. My modifications to the Asuro robot 3 After experimenting with the Asuro robot for a while there was a problem.

Every 1 ms one of the four sensors is read, so after every 4 ms all the sensor values are refreshed. I discovered that the reading of the odometer sensors was disrupted by other functions.

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. For the flashing I use the Windows version of the flash program via Wine. The locking system is made from a screw terminal. Then I took a small connector 3 pins from an old PC and connected that to the original battery pack.

A comprehensive manual is supplied to assemble the Asuro robot. I wrote a small program that continues sends the data from the odometer sensors and the line follow sensor via the infrared transceiver to the PC. Connect the USB cable to the Arduino board and the computer. I made the following corrections. My modifications to the Asuro robot 2 Line follow sensor: You can upload programs straight from the Arduino environment.
