"Conventionally, wireless controlled robots user circuits, which have a drawback of limited working range, limited frequency range and limited control. Use of mobile phones for robotic control can overcome these limitations. It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls."

"In 2009, I was challenged by [govt agency] via GTRI to develop an Unmaned Aerial Vehicle (UAV) which is piloted by a smartphone. In particular, only the sensors on the phone may be used and the flight controller must run on the smartphone. Custom electronics were allowed to interface the phone to the airframe (PHY) but those electronics could sense or control."

"After half a lifetime of dreaming about it, I’ve finally started building a robot. It’s based on a remote controlled tank, an Android mobile phone and a IOIO board which connects the two via USB."

"This article describes how to implement a very low bandwidth one way communication channel between an Arduino and an Android device using nothing more than about a meter of magnet wire, a resistor and diode. Links to a software sketch for the Arduino and the Android source code is included."

"HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone’s headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation."

"The challenge here was to integrate different technologies in a working project. In particular I wanted to use the iPhone to send/receive data to/from an Arduino, build a remotely controlled robot using a WiFi network and hook up a data logger station capturing the different sensor data."

“We decided a few weeks ago to use the Android as a remote controller instead of building a remote control from scratch. We had started developing our android controller with Google Labs App Inventor but one of the guys over at LMR did the same thing and put it on Android Market for $2. So we decided to use Chris the Carpenter’s RocketBot Controller.”

“I had this old Philips radio laying around that I couldn’t use because it only had an AM receiver. So, I thought it would be cool to make it into an iphone dock =D”
