I would like to add wifi control to my robot. Right now it uses an Arduino Mega2650 to run the main control program. I'd like to add to this contol inputs from an Android smartphone app over Wifi. What do you recommend to do this?

Unlike many cars today, Aykut Celik’s 2014 Volkswagen Polo didn’t have Bluetooth connectivity or an elaborate touchscreen navigation system. So, the Maker decided to take matters into his own hands and swapped out his “useless” radio for a Samsung tablet, putting Google Maps, Spotify and other apps right in his vehicle’s dashboard.
In order to accomplish this, Celik needed an amplifier (to replace the one attached to the prior radio), a CAN bus shield from Seeed (so he could use the steering wheel’s volume buttons), a Bluetooth module, and an Arduino Mega 2560 (for parsing data and sending it over to the Android device).
A CAN-BUS shield is necessary to be able to read CAN-BUS commands from the CAN bus line… I used this shield for detecting wheel button commands like volume up, mute and volume down. Behind the car radio there are two CAN bus cables. One of them is CAN bus – HIGH and the other is CAN bus – LOW. These cables must be connected to green sockets on the shield.
Using the SeeedCAN bus shield, you can sniff you car’s CAN bus data.
The info which is gathered from CAN bus is transferred to the Android tablet via Bluetooth. There is a little app which is responsible, for example, reducing volume whenever the wheel volume button is clicked. And a menu activity to open other apps.
You can watch the elaborate project below, and read more about it on Celik’s blog. The Maker has also made the software and other information available on GitHub.
Are you (or your kid) curious about the world around you? Google wants to help. It just launched Science Journal, an Android app that helps you perform (and comment on) simple science experiments. The app can record light, motion and sound levels using only your phone's sensors, letting you study everything from a light bulb's brightness to the acceleration in a jump. It's easy to kick things up a notch, though. You can connect Arduino-powered sensors, and Google is partnering with Exploratorium to offer starter kits to help budding scientists. Science Journal is free, so there's no harm in giving it a try -- even if you're a full-fledged adult, you might learn something.

Just got back from SXSW, where Ava (http://letsmakerobots.com/node/45195) and Annabelle, a mobile version using Ana's brain ( http://letsmakerobots.com/node/37264) built by some fellow LMR people in Texas (Lukeyes, and others), were on a panel and did standup and improv bits. Fun stuff for everybody.
Thinkers and makers at Handsome created an automated Foosball Scoreboard using an Android tablet and Arduino Mega 2560:
the Arduino is responsible only for detecting a) a goal scored and b) the gate in which it was scored. After a goal is detected the Arduino sends this data to Android tablet.
You can explore the details of the project on this blog, the sketch on Github, and watch the video below:
