here is a you tube link too see Zobor in action.



Placing your hand on the Palm Reader “scanner” on the front of the unit will activate the Great Zobor. Lights in side the case and a infinity lit mirror behind Zobor will turn ON.
Zobors eyes light up blue as the music starts to play. Zobor will look up and greet you.
Zobor will then pick up "one at a time" the 3 tarot cards and give your reading of them. Zobor will then advice you further based on your Palm reading. At the end Zobor says “that is all for now” and looks down and turn’s OFF. All the other lights will turn OFF as well at this time.

The name ZOBOR is a homage to TOBOR the Great and ZOLTAN as well as Roboz spelled backwards. It also was one of the Zeriods robots but that does not realy have anything to do with this project.
The main upper cabinet that contains Zobor is 34 inches tall, 20 inches deep and 25 inches wide. There is a Palm reader “scanner” the stick out the front 8 inches so actual over all depth would be 28 inches.
There is a pedestal “lower base” that is 40 inches tall, 19 inches deep and 25 inches wide.
So with the top cabinet on the lower cabinet the total height would be 74 inches .
The case is finished in a distressed hammered silver metal finnish. Zobor is a combination of distressed copper Finnish and black bellows type material.

This is a shot of the early concept and scale mock up. I needed to find the right scale and how much room would be required for the arm movments I had in mind.

Construction of the two part cabnet for ZOBOR. I had to use high quality lumber since I wanted to do a metal like finnish in the end and did not want alot of wood grain showing threw. I could have given it all a nice dark walnut finnish and it would have looked very vintage but that was not realy the look I was going for.

All the control electronics for the 10 main circuits are on a pull out board in the base of the top cabnet. There is a servo recorder / player unit that controls the 4 digital servos that control the head tipping. turning and arm movments up , down, left and right. The card lifter is controled by one of the head servo channels as well.
I have not found the right camera setting for the white LEDs that light up the cabnet so the pictures and videos look kind of off color. Looks great in person.

I had to get very creative to solve a common problem with digital servos. Well all RC type servos for that matter. They have a jerk or jitter on power up. And the ATX computer power supply I am useing to power this thing will put out a pulse of power when the unit is unpluged from the mains as well. I reson did not want the servos jerking around was not just because it looks bad. The digitasl servos have alot more power than anolog servos and they can actualy damage things like arm linkage and even the gears in the servos them selfs. So I found a way to use a delay relay to give the servos reduced power on start up for about 1 second then full power. this removed the start up jtter and a simple AC relay disconects the servos from the power suply if AC power is removed. The audio is a didgital play back unit and the palm scanner that turns ZOBOR ON is a proximety sensor. Here is a peek inside ZOBORs head with the back removed.

Great project John! The robot and the cabinet look great! How was the head made? Is this going to reside at the Robothut?
