Mate, I am not sure if it is of similar nature, however I have used android with my AR Drone. It uses WiFi and has a camera view on screen with a similar joystick setup.

It's so awesome I've stumbled across this. I'm making a project very similar to this for college: planning to use a IOIO board to control an RC car which is controlled by an Android app over Bluetooth. I've just got a couple questions that have got me stumped and some help would be really great of you.

I'm a complete novice when it comes to electronics, and I've spent hours doing research, so could you explain to me how the turning mechanism of the front wheels work for the first model you made? I understand a servo comes into play, and how it works in terms of PWM, but I can't seem to grasp how it works completely. I also can't seem to find a servo for a decent price.

My last question is about the motor driver circuit. Reading on the IOIO wiki says you can't connect the motor directly to the board, so a driver circuit is needed in between, again I tried to look this up and where to get it, but couldn't find anything.

Thanks!

I had made a similar app for controlling a robot via WiFi on an Android 2.3 tablet back in summer 2012 during my summer internship. It also had the video feed from a WiFi camera mounted on the bot.
We could not make a proper video for its demonstration but i had short clip which taken at its early development stage. So i uploaded it to youtube and here is the link:

I only made the app part and don't know anything about the hardware of the bot. The hardware guy told me what all control strings i had to send for different movements. :p

Android Powered RC Car

My apologies for creating this new thread under General question. However, I'm new to the forum so it doesn't allow me to post replies to an existing thread on this topic.

Robotics still remains out of reach for many students and researchers due to the high complexity of the hardware and the software, and their typically high cost. However the computing power, sensing capabilities, and intuitive programming interfaces of modern smartphones afford an inexpensive yet highly capable robotic platform. Smartphone based robots are becoming increasingly popular with many exciting applications emerging in both academia and industry (e.g. PhoneSat, SPHERES, etc.).

As a case in point, we created a robot that can recognize, track, and follow a specified color object as well as have the ability to avoid obstacles in its way.

Here is a short video showing the preliminary results:

Please share your thoughts or projects, I'd be happy to hear any suggestions as well.

Thanks!

    Hello Everyone,

    I am a Computer Science student at Montana State University, and have taken it upon myself this semester to develop a IOIO based R/C Car controllable by an Android to Android communication platform.

    I have recently had a good deal of success with my prototype, and I have decided that it is mature enough that I can share it with this community. Please take a look at my Github repositories and my blog outlining the project details:

    https://github.com/Legomaniac

    This is my first major Android project, and I have been learning as I go with this since there is no Android development class available at my University. I realize that some of my code may not be fully up to par with the Android standard, and I am looking forward to gaining input from more experienced developers. It has always been a goal of mine to either start my own open source project or a fork of another, and I believe this is the perfect opportunity to do so.

    I think there is great potential in a collection of "shields" for the IOIO similar to the expansion shields that are popular with the Android platform. I have based my project on the concept of a "shield and app combo" that, when refined, could provide a "plug and play" experience in using the IOIO with hobby R/C equipment.

    Any input you may have is greatly appreciated!

    Sorry for the bump, but perhaps the Youtube video might entice some responses?
