I am just starting with my EZ-Robot. It will be a Wallee.
I have most of my function software writen and on the bench at the moment.
track servos - arm servos - look left / right servo - look up / down servo - distance sensor /servo
Couple of questions are beginning to pick at me.
Once I install all this hardware into my Wallee, will I be dependant on interface with my computer to use it ? I would like to be able to take him away from the house and show him off to friends and such.
What internal device can I use inside the Wallee to recognize audio commands ?
Anyone have a good method to do the "look up / down" without the bulky servo outside ?
I do have a servo for moving his eyes, this came from DJ's early wallee project at www.Instructibles a couple of years ago.
With the distance sensor mounted in fromt of wallee's neck, any input as to where to mount the camera, not too keen on the idea of putting it in his eye.
Everything is beginning to take shape at the moment, still need to work on the camera though.
Having a blast and enjoying it. Nice being retired and having a few dollars to do this with.
Everyone have a fantastic week and enjoy your expierences with DJ's EZ-Robot kit.

On the u-control Wall-E toy?
I think there are some projects on here that use a mini servo mounted in one of the eyes to pitch the head up and down, but I think this would sacrifice the standard mounting and the eye-flap function.
I have been working on pivoting at the bend in the middle of the neck, but it means rebuillding most of the upper neck with a new hinge. A mini-servo provides the action, using some of the gearing recovered from the original neck works.
So far, I have a "meccano" frame that pivots as it should, but with any load on it, the plastic teeth are slipping in the gears. A more rigid mounting of the servo may solve the problem, as may limiting the travel so the head does not tip too far forward.
After that I hope to use the top of the neck mount and keep the head hinge standard.
The problem is one of leverage - too much weight on an arm even only 5cm long is a lot of work to lift at the "elbow". Moving the pivot higher to just under the head means the servo will stick out again unless there is way to re-gear it and provide a hinge.
I will post some pics soon whether it works or not.

You could try control cables for RC planes.

Or the servoless retractable landing gear as mentioned in another thread.
Get Teflon tubes used for rc planes and run music wire through them thinner wire makes curves easier. Use a high torque servo though as adding turns adds resistance.
I can see that using cables would let you mount the servo further away, but I still need to hinge the head/neck some how some way.
