I know I should finish Melvin before starting a new build but Josh's Jarvis has inspired me to give my JARVIS a physical form.
Some already are aware that I already have a JARVIS like system installed in my whole house which carries out a multitude of tasks from being an automatic PVR (like Tivo but better), controlling the heating and hot water system, controlling lights... too much to list really but one day I will attempt it.
Anyway, since it doesn't currently use ARC or an EZ-B I haven't posted much about it on here, but that's changing for 2 reasons...
- To inspire you guys to open a can of awesomeness and
- Because finally JARVIS will become a real robot rocking an EZ-B.
Basing the design around a RAD V1 robot
So far all I've done to the RAD is stripped it down - why they soldered every connection is beyond me!..
A lot of the choices I make on this project will be chosen by JARVIS. I will be adding some scripting so that I can ask him things like "What colour do you want to be?" and he will choose... this should make it interesting
Like I said, his brain is existing and has been for around 2 years, with new features being added all the time. You know what, let JARVIS tell you himself a little bit about him

ill keep posted
There is a very convoluted gearbox that let's the rad lean. Your better off just taking that box out and maybe put in a couple high torque servos. The upper body is very light once the stock electronics are gutted.
Yeah, I think some of that gearbox shot across the room when I stripped it down too so using a servo was the first choice anyway, unless I can find the gearbox, put it back together and find a servo with guts that will handle the motor and basically convert the motor itself into a servo with servo guts... unsure at the moment until I get on to that part of it which wont be until the base is done with the h-bridge, sensors, mounting the EZ-B and the battery/batteries.
@Josh, I assume the motors for the tracks can safely take 8.4v without a problem? Or should I PWM it down to ~6v
Yes the Rad motors will take the 8.4 volts easily. Bret has been running his Rad/ B9 at 12 volt when we found 6 volts just didn't cut it on carpet of any kind. 8.4 being in the middle you are totally safe. The only recommendation in regards to the motors is to remove the pinion , clean/ scuff the shaft and then use loctite on it when you press it back on. That's a anaerobic adhesive. I noticed on a couple of occasions the pinions flying off for no good reason. Even happened in one of my test videos.
I love the rad robot. The only obvious downside is the lack of space. It looks spacious at first but once everything is being put in its cramped.
About the head - the Neck portion is removable so you could use a pan / tilt bracket there and keep the EZ Cam in the location I put mine. Put the speaker in the torso or base. The less weight you put in the torso the easier your waist servo can handle it. On my robot I am eliminating the gearbox portion and I'm going to epoxy it together and hollow it out with a dremel so I have more room for servo wires and eliminate the problematic gearbox.
Your saying to use the pan/tilt servos and brackets available in the store?
Well those are too small. I was thinking more along the lines of lynx motion pan and tilt bracket B , its 9.99 and uses two standard servos. The one in the store is fine for just a camera but not a fully loaded head with the camera , LEDs, wiring , maybe a speaker etc.
I may have space in the base for the speaker, I'd certainly prefer the camera to be mounted in the head somewhere.
I'm probably going to have a play with that low temperature melt plastic like what's in the shop to sort out the waist servo, not sure about the arms closing though, I've only just taken the arms apart (I cheated on the stripdown and just took them out of the torso).
Thanks for the tips, all will come in handy
The pan/tilt bracket in the store wouldn't lift (or even hold) Melvin's head when it was the original head with no visor, micro servos don't have much grunt to them.
What about the micro servos in the store? they apparently have some fight to em'.
For me im taking the speaker out of the head most likely and putting a wireless pc speaker in the chest where the gun is if I cant control the gun.
Probably micro servos for the pan/tilt.
What do you have planned Rich?
