Many thanks Akin. Your trick works very well. My arduino nano had stopped working after an incorrect manipulation of an array size. After I have fixed the bootloader it works fine. Thank you again.
Hi Camilo. Thank you for your quick reply. I have used 123D Design software. I can modify (scaling) Otto components, but when I resize the head height, holes (for "eyes", usb port, etc) also are resized :-( Sorry for this stupid problem, but I'm a newbie in AutoDesk.Another point: I'm implementing new features in Otto (Bluetooth, Lipo rechargeable battery and an android app, via MIT app inventor). I will leave you informed as the project progresses. Thanks again.
Hi Camilo. I would like to change head dimensions. How can I do it using the original 123dx file? I opened this file in AutoDesk 123D but I was not able to separate the different parts (sides, top, etc). Thank you for your help.

Nice project yours! I have a good arduino nano shield (ref. dk-nano-003 V3) but I don't know I can connect an external source to it. It is impossible to find any information about this shield on internet. Another point: I was not able to pass the cables inside the legs (please see my photo). The gap between the servo and the walls were too small. Thank you.
