I just had an idea yesterday that can get me to make a self-balancing robot without buying any expensive electronic components.
You know last summer i made a cellphone controlled RC Car which had a tabletpc onboard to get commands via bluetooth.That time , having an onboard tabletpc , save me from buying a bluetooth chip which costs about 60$.This time, to make a self-balancing robot i’ll have to have whether an Accelerometer or a MEMS Gyro to track rotation of the robot.
Those sensors are pretty expensive too.So i’m thinkin about putting my n95 smartphone onto the robot.As i have Accelerometer on the smartphone i can use it to measure rotation movement of the robot.
I tried to explain how it is going to work in the photo.
And the finished robot will look something like this:
Here is a photo of my homemade shields for arduino.
Upper-Left:Narduino2.0 – L298 Motor Driver Shield
Upper-Right: MIDI Controller with 3 LEDs for feedback
Lower-Left:Narduino1.0 -Same Functionality with Narduino2.0 except Veroboard.
Lower-Right: IR-Liqard – Data Monitoring Shield with IR receiver.
MIDI Controller Shield is the latest one i made.I used to play with FLStudio just for fun and i thought it would be fun to control pitch , modulator and volume controls with potentiometers. I used LoopBe1 and S2MIDI softwares to convert incoming serial data to a virtual midi port. I recorded a video demo. of the MIDI controller.I’ll upload it asap.
Hi my fellow readers,
Today, i’ve been working on re-building my NarDuino car project all day . So why am i rebuilding it?. Because i decided to rebuild the motor driver ,that i’ve used on narduino, onto a veroboard so i can use it later on other motor controlling involved projects. It has been quite an hard thing to do since i have no experience at soldering at all. But i just started and finished it.
Here i made another project with my brandnew arduino demilanove.In this project i intended to send commands to my laptop computer with an infrared remote controller.I used an old ir receiver that came within video card of my old computer.I also choosed to use its own remote controller to send ir signals.It turned out to be very useful.I wrote a very simple code with python which you can add more responses for different ir signals.
After a very very long time here i am again.It has been a very tiring year as it was the year that i’ve been studying for the YGS-LYS which are the exams that takes students to university by matching them by the ranking of their success.So as the exams ended , i bought an arduino demilanove which has a usb jack on it unlike my old arduino severino’s rs232 serial port.
And i started all over again doing some experiments on interaction between arduino and my n810.My first experiment was to control a light from n810.It worked very well.After that experimental project i decided make a sumobot-alike robot controlled from n810.But i needed a chasis for the project… well after 2 days i heard that my nephew’s rc car is broken.Then i took the car and afterwards i cut off all the circuits of the car to put my own circuit instead.
