Check the notes at the bottom of the video for a complete list of the individual components that went into the build. I have not published a schematic or the code just yet. I may cover those in a separate video if that would be helpful.

Hi William. The chip is potted in epoxy and to my knowledge no one has ever been ever to retrieve the firmware. That is why I eventually decided to just build and program a copy of the whole system when I kept coming across the main boards on these Hasbro droids just "dying" for no apparent reason with no way to really diagnose or repair. I also posted a video covering how to convert them to radio control, which isn't as cool as voice control, but it is one other way to salvage a dead Hasbro droid. Check my channel for that video.

Was trying to see if I could fix it but I don’t think I’m going to mess with it. Came across your video tonight while researching the toys.

Basically they play a whole series of interactive games, many with sounds, lights and even motion of the droid. You can search online for a complete menu of commands to test. Also be aware the little LED light in the center of the droid, near the base, is actually a button. It is a sort of safety feature that disables/enables the drive motors. So you might try pushing that button once, then see if you can get the drive motors going. Good luck!

Good question- never really thought about it, but I would assume the Mars rovers derive their orientation either from signals taken from the satellites which are now in orbit around the planet, or perhaps even from signals taken from their associated lander platform. It might also be possible that even though Mars does not have a magnetic field comparable to that of Earth's, it may have enough of a remnant of one to allow for magnetometers to use it for orientation. I have to say, though, that I have never heard mention of magnetic compasses used any of the Mars rovers I have seen, or at least not for navigation purposes.

Hi thank you for your interest. I do not have any close up pictures, but the rotation mostly just consists of a mini-gearmotor such as you can find here: www.solarbotics.com/product/gm18/ which is embedded into the scanner head base, which I had cut in half and machined out to be hollow. The rotation and reversing are handled by the motor controller, and there are no limit switches or any sort of feedback (other than the homing system). The back and forth rotation were just roughly programmed into the Pickaxe microcontroller based upon a set of predetermined rotation intervals (i.e. 500ms right, 250 ms left, 250ms right, 500ms left, etc.) In other words, the rotation control program was written based upon the assumption that the scanner head will always start from the same position it was facing when it deployed from the compartment- so it really has no way of sensing at which point it is in the rotation (again, aside from the homing system which only comes into play when the scanner head is lowered into the dome). - Hope this helps.

Any updates?

I bought one like this and I think a kid played with it before I got it and held the head in place so it damaged gears undernate that would turn the head. I want to repair mine too and there are wires torn loose inside the head and I don't know where they go back to.

Hi, I'm Not "officially" an Hasbro/Spinmaster/Jakks technical engineer, but as a great fan of all the SW electronic devices with zero$ budget, I got to learn everything to get all the droids in my actual collection. (i.e. 3 X Spinmaster 16" BB-8, 4 X Sphero BB-8, 1 X Jakks Pacific DELUXE 18" R2-D2, 1 X Jakks Pacific 48" Dart Vador, 1 X Hasbro 2002 like this one, 1 X FX Replica Anakin S. LightSaber, 1 X Sphero Spiderman, 1 X Thinkway Wall-E U-Command, 3 X Anki Cozmo, Stormtrooper/Bobba/IronMan Black Series & Marvel Helmets, 1 X LENOVO Jedi Challenge, 1 X LENOVO dim. of heroes, and few others still to repair.... ) All rebuild from scratch with parts that normally came from 2 or 3 similar model sold on ebay as "spare parts" =) It takes a LOT of times, but I can get what I want for aroud 10% of the avg. eBay price for a "fonctionnal" model in the same condition! Those I listed above cost in total less than 1000$ CAN, they all runs great. If you need informations or have a question, be welcome it's free =) 90% of time it's just a little thing easy to fix!

@@bobleponge8447 Hi! I’m planning to repair my dad’s droid for him. We got the R2 droid a few years back, but when we placed the batteries in and turned R2 on, his head turned to the left and then to the right and died- Im not really sure with what caused it-

Still need the sensor wires pinout ?

@@bobleponge8447 hi, I just saw this and yes that would be nice - think I even called the company and they just said they built them and that was it. With the wires torn loose you just can't tell where they go back.

Sensor Array and Telescope? The Interactive R2-D2 only includes a single Periscope. Do you mean the Holoprojector and the Periscope? The holoprojector is the silver knob on the top of his dome, on one of the blue panels, and the Periscope is the two-piece attachment that goes on his left upper dome flap. I believe there are a few listings on ebay for them, but it does cost a little bit. I just recently purchased a replacement door panel, as well as a whole second R2 to possibly do a mod on. I'll take a look at ebay and leave some here. Here's one listing for a REAR holoprojector, but I'm sure you could get it to work in place of the top one. Might take a little gluing, or some fidelling. They appear to be very similar pieces.www.ebay.com/itm/Star-Wars-Hasbro-R2-D2-Interactive-Robot-PART-REAR-ILLUMINATING-LIGHT-HOUSING/382640691688?hash=item59172999e8:g:an8AAOSwanxf~~Fq As for the two Periscope assembly pieces, I'm not sure. Keep an eye on ebay, it'll show up eventually.

Check the wheel lock button above his third leg. If it is lit up red, he is in a special mode that prevents him from driving off of tables and whatnot. If you press it, the red light will turn off, and he will be free to move. When turned on, it will always start in wheel lock mode.

Mine won't turn on at all haha

@@Yeti1473 Really?? I'm waiting for mine to show up in the mail this week. Are they crap from the very beginning?

@@Evadious-2022 Probably not, I bought mine today from a comic store. It was already out of the box and used by someone beforehand. I'm sure yours will work fine!

@@Yeti1473 yeah that sucks yours is not working properly. I mean I am not going into this blind expected to get a $600 quality lightsaber but I also hope it is not a total piece of shit

@@Evadious-2022 I spent $55 on this without even knowing what it was lol. I just thought it looked cool and I don't have a big R2 yet.
