Few weeks ago, Explorer-27 was a short, dog-sized robot:

and after weeks of further development..

 

fast prototype using sticky plasty to form a tablet holder.

alot of time spent to cut the aluminium profile and attach them securely with nyloc nut and spring washers.

Afterwhich, I also built the new paper model dog head(Husky) 

And installed the LED eyes into this new paper Husky head.

Re-code the UI in Unity and also connect it to the Arduino system.

After the program in Unity works, I exported it into a working file and installed into the windows tablet to run the system program for the robot. The head is also attached to the new robot body.

Head with the UI animation.

As you can see, when the user moves the robot, the eye will follow the direction, this was done by transmitting data from one Arduino to the other using I2C protocol which connects multiple arduino together and then to the Unity program in the windows tablet.
