We are a hungarian father and his son (sorry for my poor english). I bought a EZ-Robot Hexapod for my son, who is interested in it.
I bought it from ebay. Unfortunatelly the seller suck me in - as it was advertised as new, and what we got was opened original box and 2 pcs. cracked house servos.
It was the begining of our story.
I'm a hardware development engineer, so I understand what the Hexapod does and why it is working and how ...
There are several problems what we don't understand, I list it:
1. We power on the Six, we connecting - it is working. After a simple movement/action the Six's 1 servo frequently vibrate and give rattling sound - not always the same. If I touch it with my finger I feel which one is vibrating.
Is it normal?
If I fine tuning the servos for 90, then the problem still exists.
What can I do with this?
2. I try the tracking function of the camera. I trained an object by Six, and if I try Six tracking this object it is locking the object and sometimes Six turn away about 30-40 from the locked object.
What I do wrong?
3. Mobile app
We have mobiles and tablets with several screen LCD resolution, but the deafult mobile app doesn't display perfectly on the screen, for example the left, forward, reverse, right buttons and main background image is not square rather rhombus.
What do I wrong?
OR why I can't change the main's width and height 800x480 pixels?
4. Can the servo's fine tuning values loading on power on to the Six?
We tried to calibrate the servos, but 2-3 couldn't set by mechanically, only by fine tuning.
So, that are the first problems for us. Could you help us?
PS: we live in Hungary/Europe, how can we buy servo for good price? The price is ok, but the shipping charges are very high, for example from Brookstone the shipping and custom charges are 3x more then the servo's price!
