Wireless Robot with Web Controls

Any good SkyNet starts with a robot. Well, we are in luck…User “badcat89″ posted in our forum about a Web-enabled, Wireless Robot that is controlled via a web interface. We can imagine a swarm of robots controlled by data received from the web.

The robot uses a pair of serial bluetooth adapters to form a wireless link with the ioBridge IO-204. The serial levels of the IO-204 are TTL and a circuit using the MAX-232 was required to allow the serial interface work properly. On the robot is a set of serial servo drivers that control the steering and speed.

The interface is standard web page using an embedded ioBridge.com serial widget to make the connection to the IO-204 base station module. You can control the direction and throttle by clicking on the itnerface and using the up and down arrow keys on your keyboard. The interface generates serial strings that the serial servo drivers react to when received. You can see the strings and the serial widget in the debug part of the web interface.

Here is a YouTube video of the web powered robot in action – looks like a lot of fun to drive. One step closer…

Wireless LED Sign – XBee + ioBridge

OharaRP created a wireless LED scrolling sign that displays messages received from the Internet. The sign uses an array of 8×8 LED modules connected together – expandable to 16 segments. The LED’s are controlled by a MAX7219 controller board that can receive messages from an Xbee wireless module and is power by 5VDC (using a standard mini-USB plug). The sign has a wireless base station that forwards text and commands towards the sign relayed from Twitter or an ioBridge widget embedded on a website.

In this photo OharaRP sent IOBridge to the sign from his iPhone.
