Jarvis Hacked Omnibot 2000 W Pc ,Ezb &Amp; Vacuum Inside By Josh Starnes

Jarvis is a project inspired in part by Jarvis the AI that belongs to Tony Stark in the movie and comic book series IRON MAN. This is my first real robot with no previous experience. I dreamed of making a couple of robots one was a vacuum robot with 4 motors. Brush, impeller, and one motor.driving each wheel. This was back in 98 before roomba was thought of. Lol my drawings as a kid even resembled one. Now that I am older and have tools like EZ Robot I can start making these dreams come true. It has been a learning experience and I hope to learn more. Jarvis is basically my personal computer but also will have a few key features. Goals are that he can help maintain a home by vacuuming and sweeping the floors. My fish need to be taken care of while I am away so scheduled feedings and turning tank lights on in the morning and off at night are in the works. Jarvis can answer calls , act as a telepresence device because he has a camera and screen. He would be great for security by detecting motion, taking pictures or video and sounding.alarm if intruders are detected. Just for fun I would like Jarvis to bring cold beers to the table when asked to which I am sure would be a great conversation piece. Jarvis will be autonomous in some.situations and because of the wireless video link by wifi and wireless keyboard and mouse, I can be checking facebook on either the upstairs or downstairs Tv while Jarvis is roaming the house or cleaning. Thanks to 4g USB antenna Jarvis is not limited to my home and can.take control quest (or kill.switch.lol) from a smart phone or laptop. This makes the Jarvis project.show friendly as I can take.him to show off without lugging around a laptop or other equipment. Also i do plan to somhow work in being able to control his base movements , head ect from a ps3 bluetooth.controller. I'm still thinking of other tasks Jarvis could do but I gotta get this guy together so there is no time to waste!

February 1012 when I first received the Tomy Omnibot 2000 . My starting main parts were/are asus mini itx motherboard, 8 GB ram , Win 7, 250gb Western Digital Hard Drive, Nvidia 560ti graphics card, 2 ghz AMD 25watt tdp dual core CPU, Thermaltake 430 watt psu, 460 watt apc backup, Ez Board Kit w EZ WIRELESS CAM , Shark vx63 cordless vacuum, 4 Power Sonic batteries 12v 9ah , power HD 240 oz servos, hitec 645mg 130oz in servos, hitec 5995tg 400 oz in servos , Robotzone.gearbox 5 to 1 ratio for shoulders and other electronics.

At this time im getting the body ready to start putting things together. The fun begins!

@Rgordon , yes the 1501mg is a quite servo. It's mostly due to being analog. A digital servo is likely to buzz because of the high refresh rate. I believe it's 300 times a second it pulses the motor and this can make a electronic noise. I will link the servo city gear boxes I have.

Ok here's my gearbox , the price changed because they are no longer offering the Delrin Gearset I have. They only offer metal gears now. This accounts for the price difference but I suppose with Delrin they had a handful of customers strip some gears. I love the quality it is very good. I have not put them through any ridiculous load tests simply because I went cheap st the time and took plastic gears. The 1501 mg is 284 oz in torque at 7.2 volts and 240 at 6v . With a 5 to 1 ratio that is up to 1200 oz in at 6v and 1420 oz in at 7.2 volts. Even at 6 volts this should be plenty for a robot arm.

Ok so since we were already talking about arms I am thinking I will get 2 sprockets made to fit directly onto a servo and a adjustable chain. Here are some pics from servocity where I am buying them from.

The linkage setup I have works but it has a tiny bit of play and it can bind and lock in place if move too far in either direction. So I'm going to remove that problem by using a small chain drive system

Slightly updated idea for the elbow that still keeps weight close to the pivot point and cannot bind.

Wow... $80 per gearbox. But the metal gears will pay off in the long run. Might be awhile before I order any of these. Thanks Josh for the info. Always there when I need ya...

Hey I understand , it was a pretty penny to buy the gearboxes and all the servos I did at the time. I believe for it's purpose it solves a lot of problems one encounters when mounting a large arm to a body.

Hey Josh, you can make the sprockets work for you too. Since you will probably only bend at the elbow 90 degrees, you can make a 2 to 1 ratio on the gear sizes. Smaller gear on the shoulder and larger on the elbow. That's if you need more power and not as much speed.
