A new Android app has been created to make it even easier for you to control a number of different commercially available robots, including the iRobot Create, LEGO Mindstorms, VEX Pro, and, of course, custom-made Arduino cellbots.
The Cellbot application was written in Java using the Android SDK and is available as a free download from the Android Market for any Android 2.2 (Froyo) and up phone. Watch the video after the jump to see it in action.
Features of the Cellbot App
The Cellbot App’s remote control feature allows you to use a number of different methods on your phone to control your robot, including a directional pad (D-Pad), a joystick, the phone’s accelerometer, or voice controls to suit your needs. This flexibility ensures that users can choose the most intuitive and convenient method for their specific application, whether it be for educational purposes, hobby projects, or even professional robotics development.
The commands are sent via Bluetooth and are limited to a range of around 25 feet or so. However, this can be increased if needed by mounting the phone to the robot and putting it in Brain Mode. In Brain Mode, the phone essentially becomes the robot’s brain, allowing for more complex interactions and extended range. You can now connect to the robot and chat with it via Google Talk, where you can simply type text messages such as ‘move forward’, ‘stop’, or ‘picture’.
Practical Applications and Examples
One of the most exciting aspects of the Cellbot app is its versatility. For instance, educators can use it to teach students about robotics and programming in a hands-on manner. Imagine a classroom where students can program a LEGO Mindstorms robot to navigate an obstacle course using voice commands or a joystick on their Android phones. This not only makes learning fun but also provides practical experience in coding and robotics.
Hobbyists and DIY enthusiasts can also benefit greatly from the Cellbot app. Custom-made Arduino cellbots can be controlled with ease, allowing for endless possibilities in home automation, personal projects, and even competitive robotics. For example, a hobbyist could create a robot that can be controlled to fetch items, take pictures, or even perform simple household tasks, all through commands sent from their Android phone.
Moreover, the app’s ability to integrate with Google Talk opens up new avenues for remote control and monitoring. This feature can be particularly useful in scenarios where direct Bluetooth control is not feasible. For instance, a researcher could deploy a robot in a remote location and control it via text commands sent over the internet, making it possible to conduct experiments or gather data from afar.
The Cellbot app represents a significant advancement in the field of mobile robotics. Its ease of use, combined with the flexibility of control methods and the ability to extend its range through Brain Mode, makes it an invaluable tool for educators, hobbyists, and professionals alike. Whether you’re looking to teach the next generation of engineers, build a custom robot for a specific task, or simply explore the possibilities of mobile robotics, the Cellbot app offers a robust and versatile solution.
