R.O.B., the Robotic Operating Buddy, is a classic accessory that was bundled with the original NES. ROB is used to play two of the NES launch titles Gyromite and Stack Up, but in many cases the robot will have difficulty moving. On this week's Fix it Friday, we show you how to take apart ROB and repair any issues with the gears that control his movement!

Those wave washers look to me like a rudimentary slipper clutch which are designed to give under load i.e when a kid presses down when they shouldn't. I think what has happened over time is that those washers have lost their tension so the gears slip under not much load. Your fix will work but you will have lost the functionality of the slipper function. .

@Asriazh 3 года назад

I think those wavy metal springs you glued on is supposed to be working as a clutch, so the motor wouldn't be damaged when Rob is already at his end movement position but the motor keeps spinning for another second or so. I wonder if glueing those springs down would damage things over time. Maybe glueing a rubber ring on to the gear side between the springs and the gear would be a better idea to create more friction for reliable movements?

@LIRetroGaming 3 года назад

That’s interesting, I think the metal components might be a clutch. But it’s also very clear that Nintendo glued them to the plastic as well. You can see that glue on untouched ones that still work

@Asriazh 3 года назад

@@LIRetroGaming I guess it's kinda hard to figure out how things were originally. Maybe the metal wavy part was glued on on only one side to prevent slippage from at least there? As long as everything is working better than before, things are fine, i guess, as long as the motors are ok with it. we should ask them *lol* ^_~

@stevemcknelly5036 3 года назад

I always wanted one of these as a kid. One of the things that occurred to me as you were working on this was whether or not someone should go into a Rob and model all his gears so they can be 3D printed at a later date for replacements. Otherwise, great video as always!

@LIRetroGaming 3 года назад

Yeah it would be great to be able to reproduce those gears. However I think some of them might be standard sizes that can still be purchased

@EvatronX 2 года назад

i had that same thought. youll be glad to know someone out there are 3D printing spare "clamp" hands and theyre actually not bad quality. mine can pick up the gyros so yeah you could 3D print a bunch of spare parts for R.O.B

@johneymute 3 года назад

I tryed it a while back but i failed to get it working properly,, i sometimes wish Nintendo just used square shaped metal sticks instead wich were only round at the edge and if nintendo just designed those gears in that they could only fit to those metal gears, this sothat those gears would never slip off, this sothat you never had to glue them again,if, I still think that a company could make modern gears for those rob robots sothat you never have to replace them again.

I was so overjoyed when I bought a near mint condition in box deluxe set back in 2008 at Play N Trade in Prien Lake Mall paid like $ 200 + something like that. I would love a 3rd party to develop some new game for him it would be wonderful especially with a new accessory play set

@tristanmartin9030 7 месяцев назад

This video is helping me attempt to repair a ROB I just bought with most of the accessories. He has trouble going up without "assistance", and cannot turn at all. Should I add any type of lubricant to the gears, and if so what kind? I also have found that when I manually rotate the gear sets for either the base or torso they only like to rotate in one direction. Going the opposite direction makes the gears pop out! Is this just because the unit is opened or do I need to fix something else?

@johneygd 5 месяцев назад

Definitely a great fix wich might be doible for everybody😁

@greggv8 Год назад

Interesting that one of the gear racks in the center column is just for show. Looks like it was designed to have two gears but Nintendo only installed one to save a few Yen. What would be neat to see is how it does the up and down movement and the arm movement separately with the gearing connecting left and right uses a common shaft with the up/down final gear bonded to it. An experiment to try would be to quiet the gear noise with some of that thin yet super sticky white grease often used on plastic gears driven by small electric motors.

@aramusbelmont4992 7 месяцев назад

That is for sure a clutch. The correct repair is to replace the spring that has lost it's tension over time. By gluing it shut, if the arm ever gets caught against something, it's going to break the gears or motor instead of slipping.

@lv99gamingwiz Год назад

Do you happen to know where I can get replacement discs for ROB or if they can be 3D printed? I picked up a "Like New" Deluxe Set and the discs are missing.

@LIRetroGaming Год назад

I believe that there are some 3-D printed projects that allow you to make new gyros for gyromite. That being said, it’s not too difficult to find replacement gyros out there.

Hi, cool video. I am missing two gears in the main body. Any idea where to get them from?

Not sure where to get replacements other than from another ROB. Although there are plastic gears that can be purchased, you probably need to know the diameter of the gear and the number of teeth

@relo999 2 года назад

Great video, thank you. The problem I are having with mine is that while he moves up and down he does not stop at the correct points in either direction. Mine always skips a step in the vertical movement (effectively having 3 up and down stops instead of 6, 4 if you count bottoming out) but I do hear the leaf switch clicking in position. Those 3 positions however work perfect. Any idea how to fix it?

@johns8369 Год назад

I repaired the vertical cog mechanism. But there's an odd clicking sound when he lowers himself. Is this normal? It seems to work fine, but I worry it may be breaking slowly.

@LIRetroGaming Год назад

It sounds like something might be installed wrong when you reassembled it. But it’s hard to know for sure without looking at it

@nickolaswilcox425 Год назад

thats good to see, thats the issue with mine, failed slip gears, those metal/plastic assemblies are supposed to allow it to move if forced or if it goes past its intended bounds, but be rigid enough that it will move and hold position, got mine today and first issue i found after fixing the battery corrosion was the rotation not working and the rail movement isnt quite right, but im fairly sure that part is just it needing to be cleaned

@frankbizzoco1954 3 года назад

Thats my Fami-Rob! His first problem was that one gear wouldn't even stay on the vertical track. His body just dropped. So as you saw, I glued that one gear in his body. Guess it didn't hold lol. Also the leaf switch in his back was messed up, and the one in his "feet" was slightly off, and he was getting hung up going left and right. The bottom one could be salvaged, but the one in his back could not. Putting him back together was a pain because you put one gear back, and two more would pop out. Thankfully I took plenty of pictures. This was the most comprehensive video I have seen on the subject of fixing Rob. So I hope it helped someone give new life to their old Rob, or fix Ebay junk so he works again. Thanks again for the repair!

@RoyalDogmeat 2 года назад

Update: I fixed him! And then the motor started grinding horribly and sticking again right after.🥲😂 not a huge deal. R.O.Bs still R.O.B, and he’ll always be my little childhood buddy lol. Maybe someday I’ll buy new parts and properly get him working again!

@jenniferneal4727 2 года назад

Great video, thank you. The problem we are having with ours is that while he moves up and down he does not stop at the correct points in either direction. Probably related to this is that when rob reaches both the top and the bottom the motor clearly runs for another few seconds as if it doesn't realize it has reached the top or bottom. This is really a problem when trying to spin the gyro because he doesn't stop moving down and his arms push down on the gyro disc so it stops spinning. Do you have any thoughts what needs to be repaired or adjusted for this issue?

@LIRetroGaming 2 года назад

There’s a little switch on his back that helps determine where his vertical position is, And sometimes it gets misaligned when you reassemble it. Can you check and make sure that it’s in the right spot?

@Xoferif 3 года назад

What does it actually do, though? The grey version has coloured cylinders on supports that slot into the base. Does it play Towers of Hanoi with them or something?

@ITNODove 2 года назад

This was five months ago so you've probably already found out the answer. For anyone else reading though: R.O.B helps you play two games: Gyromite and Stack Up. In Gyromite he moves a spinning top onto a button when commanded which shifts doors back and forth to help the player move forwards and avoid enemies. This uses another attachment which isn't shown in the video. In Stack Up you're shown an arrangement of the coloured cylinders which you must recreate by having ROB move them back and forth until they're in the correct order. This game doesn't have a method of testing if you've played correctly though, it works on an honour system. Hope that helps!
