MorpHex - hexapod robot can tranform.

Hexapod robot is fun to watch, and MorpHex is even more awesome. It can transform to a ball and then back to normal hexapod. The transformation is incredible! Let's check out the video demo:

Extra Robot Hand help your daily life.

Supernumerary Robotic Limbs (SRLs) are the robotic limbs to help when you have both your hands busy. It is very helpful for field workers, sometimes you do need extra hand but no one is around you.

You can see how the SRLS can help in the above video.

Android Robot - Auto pilot project

Android smartphone is a very powerful device, with GPS, digital compass, gyro, and accelerometer inside, which can be a great platform for making robot. Moreover, the dual core processor inside can perform intensive calculations as well.

In order to let my Galaxy Nexus to control the motors, I used the cheap wifi router: TP-LINK WR703N as a wifi to serial bridge to my motor boards. I can simply send tcp packet to control the motors.

My ultimate goal is making an autopilot robot using GPS, but the result is very bad as the best positioning accuracy is only around 10 meters. I think GPS reading should only use as reference, I may need to consider other sensor readings to calculate the best estimated position of the robot during navigation. 

Anyway, here is the screenshot of my app:

Here is the video showing the robot using digital compass on the phone to adjust the orientation:

For GPS and digital compass programming, I would recommend you to read this project:

The source codes show you how to read the compass and gps data, also calculate distance and bearing of two locations.

Finally here is the video showing the robot in auto pilot mode, use GPS and digital compass to navigate.

Brain Wave Sensors with Android OS

 For disabled people, may be has difficulties to control a smart phone, now using Neurosky's MindWave Mobile (Brain wave sensors) as an input device to any Android device. Though the app presents very limited information, it is still a good demostration.
