Now I have the EZ-B kit and the Hearoid it's time to start my Showcase thread.
I still haven't decided on a name for him yet, all suggestions are welcome.
I won this robot on ebay weeks ago, for the past 2 weeks he has been waiting for me to collect him...
Today was the day, a road trip to pick him up and bring him back to his new home...
In his new home (with Omnibot and Wall-e in the background totally unaware they are next in line to be opened up)
It wasn't long before this happened...
Now waiting to go in the dishwasher to get nice and clean.
The plan is to make him autonomous, running 24/7 (except for when he knows to go charge himself up) but will also be adding in the various image tracking options.
The only other slight modifications to be made to him are to convert the head to tilt & pan which will involve having to give him a small neck.
The head will include the camera. I haven't yet decided to fit it in one of his eyes or to make it his nose. The issue to overcome with this is the blue tint on the bubble head. The mouth will have a light or some lights in which flicker when he speaks.
The arms will be given some life with servos at the shoulder joints and the elbows provided I can get them to fit in there nicely.
Ultrasonic sensor will be in his chest, probably on a servo to give a wider view.
Original drive wheels and gearbox seem to be in very good shape so will plan to reuse those and just replace the existing motors for the modified servos if they can manage the task.
Speaker and microphone will be in the original positions - if it's not broke why fix it?
Not too big a project but enough to give me a test, help me learn and bring an old robot back to life.

MELVIN was the other guy in the movie i think (grim reaper name ) been about 12 years since i saw it at the movies.

After looking at the arms and now knowing that keeping the project as close to original as possible isn't a goal I may be building new arms for this.
While I have managed to build the servos in to the arms and have them strong enough to lift with no servos on show I'm still not satisfied with how they look.
So time to plan and build 2 new arms and hands, when funds permit. They may require a second EZ-B though, depending on how I do them.
So, arms are once again on hold while I save for the hardware needed to build the new arms. Unless I suddenly become motivated to mess around with the originals again...
At least I can make them in a way that I'll be satisfied with them though.
In the mean time at least I can get on fitting the IR and ultra sonic sensors and the LCD display (when it turns up). I may even break out the Wall-E and give that a new lease of life.
Regarding arms, my personal opinion is to go beyond the strength to move, while taking into account the payload to be lifted. When using a small servo to move an arm, can run a few days, or months, but it ends up breaking or making noise or losing precision, also have internal gears wear and break ball bearings. To me all that has happened over time. But there are cheaper solutions such as high torque s8166m Turnigy 30 kg of force, for GBP 21.99 ideals shoulder. You could make a skeleton arm in aluminum and mounted above the original arms, or part of them to preserve their originality. Then a low cost sevo as MG995 (or otherwise) of 15kg of force may be valid for the elbow, as long as the hand is not too far from the elbow or weight too large. For example: with 15kg of force on the elbow, and a long hand of 25cm (10 inches) could lift a payload of 150 grams (5.29oz) Given that the arm piece that goes from hand to elbow weighs also about 150 grams (5.29oz). I really like the theme of the arms and the arms build reliably prevents you a lot of trouble in the future, substitutions servos and mechanical wear. Helping with arms is what relaxes me my.

I have the highest torque micro servos I could find in the elbows running on 6v now which solved the issue it was having.
I'm just starting to want to build new arms though, especially now that it's so far from the stock look I was aiming for at the start, some 5 months ago.
I've been tempted by the arms in the store here, or something similar. But then again I have some other plans with some great detail too, however would require a second EZ-B installed and some way of fitting 5 servos in the lower arm, 1 in the elbow and 2 in the shoulders... A task that may prove to be impossible but I'll still attempt to draw it up at some point.
The arms aren't going to be used to pick anything up really, or at least that isn't the plan. The robot isn't going to do much other than whatever it wants (roam around, dance, sing, cough, sneeze, sleep, watch TV, talk), it's not like it's going to be a helper robot, more a pet robot or a social robot.
I guess my idea on my omnibot project WONT, work is made for lifting over 200lb,its easy to find how much it lifts by the ,only reason i have it that high you use only half the current or less.
That how i design my servo's for arms or anything ,i make so it gives more then 2 times the current and only run it at half the current.
HOPE RICH understands is only a suggestion i have.
