Star Wars B2EMO appears to be a practical effect rather than CGI. A real B2EMO was featured at the recent premiers of Star Wars Andor and several influencers have posted footage on social media.
As far as I can tell this was built by the same team that built BB-8 which includes Josh Lee and Matt Denton, and you can see the BB-8 internal animatronics reveal from Star Wars Celebration 2016 in the Star Wars RU-vid channel.
At first Star Wars B2EMO doesn’t look like anything special - it’s a beaten-up looking salvage Droid. During the Star Wars Andor premier however, the first thing I noticed was that it had Mecanum wheels, which makes it omni-directional. I’ve done a few projects with standard omni wheels in my channel, but never Mecanum wheels. These wheels have little wheels around their circumference which are angled at 45 degrees. Mirrored pairs are usually installed on the robot, and depending on the combination of rotation on each wheel, the robot can move in any direction.
B2 is even more complicated than that though. Each foot can lift up and down independently, and also the whole wheel-base can extend to make it longer and presumably more stable. There are also a number of other features in the body, which can boost itself up to make the Droid taller. There are rotating parts inside the body, and the head can also move independently in multiple axes. And all of this is a real piece of engineering.

So many clever little solutions! I love how you're avoiding the "Anything can be built with enough money" idea and implementing the knowledge you've gained from past projects. Loving this project!

@Wico90YT Год назад

The project planning is always on point. Always building on prior ideas so its easy to folow

@catch22exodus Год назад

The active suspension system makes its movements appear so organic, like a living animal, and combining that with the meccanum wheelbase makes it such a compelling creature to watch. It's a sort of hybrid between animal and mechanical locomotion. The combination gives the machine so much personality and character! Amazing job!

@AJ-Palermo Год назад

I couldn't agree more. It would be cool to add a toggle switch for organic/mechanical mode, in organic mode it would lean into the direction of motion, and in mechanical mode it would act like a car, leaning forward while braking and backward while accelerating. Or even better, add more joysticks/thumbsticks like James was saying

@FifthConcerto Год назад

B2EMO is definitely my favorite part of Andor. I remember seeing all of the movement and thinking how difficult it would be to get all of that working in one droid. And then I thought, "I bet James could do this." Then I saw the teaser thumbnail for this video, and knew immediately what was coming. Not only did you not disappoint, your use of so many lessons from previous projects is inspiring. This is exactly what it is to be a savvy engineer.

@WellingtonIronman Год назад

There was definitely an ‘ahha’ moment as you were operating the chassis. You could see with all the different motions available how you could convey emotion with the droid, which, in my opinion, is one of the most important aspects

@H34... Год назад

Love the statement of you can do anything with a lot of money, but sometimes its just more fun, or more nessecary to make due with a cheaper solution. Looking forward to the rest of this build series. It's a very animated droid with a lot of character to its movement.

@johnkelly7264 Год назад

Just a thought for a new project.... How about a plain looking robot about the size of 2 shoeboxes that you could put on the floor, and it looks after itself, goes back to a charger (Kennel), can wander around the house independently, and handle a step or two. All the while learning its environment so it can be commanded to go places that it remembers. An electro mechanical version of a pet that you could decorate any way you like, or just leave it as a rectangular box. That would be so cool, I'd certainly build one!

@anon_y_mousse Год назад

@chromosundrift Год назад

"You can build anything with enough money" - very interesting point and an important lesson for most of us! How to build with a big vision and a small budget is the eternal question.

@Dysiode Год назад

Wow! It's so simple for the amount of expression it has! I can't believe how well the suspension works, for being an elastic band and a zip-tied string attached to a motor...

@DavidThornley Год назад

Love the vehicle! There's an error that you've sort of got away with: the wheels need switching around. The iteration in the video can yaw because the wheelbase isn't square. As you extend the chassis, the axle of each roller contacting the ground - not of the mecanum wheel per se - approaches lining up with the centre of turning. That often happens with one wheel at a time, because any motion of the chassis (with any yaw) can be viewed instantaneously as a rotation around a point, and that point will cross the axes of various rollers as the trajectory changes. With your chassis extended to place the contact patches on the corners of a square, it would rotate freely with the wheels locked, which tells you that you can't drive yaw reliably in that configuration. You'll still achieve some yaw with the video setup if you extend far enough to be square, but only because the mecanum wheels have some width, which means that the contact patch sawtooths either side of the centre line off the tangent, and hence the roller axis rotates slightly relative to the radius. Switch the wheels (front to back or side to side doesn't matter which) and it will behave much better because yaw will always be well constrained. When I make a mecanum wheelbase, my mental checklist includes "if the wheels are braked, does it definitely constrain translation and rotation of the chassis?" You can set the servos/motors to station holding and feel how much constraint you've got. I haven't investigated the specific effects of canting a mecanum off the vertical as happens with your suspension. It will certainly distort the contact kinetics, but I don't know how significantly. How are you generating your rollers? I have a CAD construct that does it fairly simply if you're interested.

@MagivaIT Год назад

one of the best so far i think. hope you can get the wheel motors inside the wheel or above to give it more of a simitry look. i thought you would do the extender mechansim like a car jack ? you could even motorise that too if needed. the animation of this is great thus far, love it

@BenRyherd Год назад

Loving this build. For additional controls a head tracking unit (IMU like they use in FPV goggles) might be a nice way to control the body stuff because it'd be a little bit intuitive for you to turn your head to turn the robot's head and stand up straighter and crouch down slightly to handle the vertical growth of B2EMO. Also really impressed by you noticing that you had an extra DOF for stretching the wheelbase. Another drive motor probably could've handled that too for relatively minimal additional cost, but I appreciate the clever solution.

@PachezZ Год назад

using a gyro in a remote to controll leaning of the body would be another intuitive option

@Rockhopper1 Год назад

Hi James, I am the chap you met at the maker's faire at the NEC earlier this year, I was in the blue electric wheelchair. I have been wanting an off-road version for ages and considered it with my limited engineering capability. There is an off-road chair but it is mega expensive. Then you pop up with this, if you beefed it up and put a chair on top and put an electronic (drone) gyroscope thingy on it to keep the chair level this would be brilliant. Well done.

@10p6 Год назад

Much cooler than I thought it was going to be. I think you should reverse the wheel units though, with the motors on the inside (as opposed to outside now) to give a longer stance.

@mikeydk Год назад

To help combat drifting on the length extension, maybe you could make some kind of brake for the gear in the middle, could be some kind of flat bevel gear where one can rotate like it does now, and one can't rotate around the center rod, but slide up and down. A RC servo can then lift the non rotating gear up to allow the other to rotate, drive the wheels to the wheelbase you want, then lower the non rotating gear down again.

@niklasw1631 Год назад

If you turn the suspension 90 degrees so that the link arms point in the forward and backward axis, the same as the radial wheel axis, then it would eliminate the issue with the feet getting closer. It would also be easier to compensate the wheel body to always be parallel to the ground. Just a suggestion.

@akaHarvesteR Год назад

A new star wars droid build! This makes me so happy :D I found this channel by the BB8 builds, and to me all the star wars builds (and hulkbuster) were your best projects. Something about how you solve problems when you have very little information about the actual prop droid, the super clever mechanisms to reproduce all those motion features, it's brilliant stuff. Can't wait for the rest of this build series.

@Stoneman06660 Год назад

@DeadlyAssets Год назад

Absolutely Amazing! Your skill and workarounds for seemingly difficult problems that you make look easy & I know from trying to work out solutions (mine purely in code) leave me awe-struck by your elegant & straightforward solutions. I applaud you, if I had half your skillset I would have built an exoskeleton for my paralysed left arm & be working on ways to help my dog (the second one to get Degenerative Myelopathy, the first passed about 15+ years ago after having his back legs on wheels for a year until he was ready to go on his final adventure) I know there must be a more elegant solution easier for both us to get her into and her to use when she gets to the point she can't carry her own weight on her back legs anymore, she is already dragging her knuckles as she walks. After watching this build, something based around this possibly could even allow her to crouch to do her business. Sorry, I'm rambling, but your builds always spur me on to try to design something, build it and see what happens. If I was only fitter & wasn't so exhausted all the time, I would have been inspired by your channel years ago & wouldn't have so many piles of shame sitting around my home, including 3 FDM printers that need mending (2 are just clogged nozzles I'm pretty sure) my ill health, unfortunately, holds me up & my meds while allowing me to function, keep my concentration very short. Watching your channel always amazes & keeps me entertained, whilst inspiring new ideas or sometimes allowing me to revisit old ideas from a new angle! Keep it up!

@Fireheart318 Год назад

I’d absolutely LOVE IT if you made a T-180 racecar from the movie, Speed Racer! T-180s are basically jet cars with swerve-drive wheels, which allows them to point their jet engines in any direction without losing wheel grip, effectively double-dipping on acceleration, braking, and steering. The cars in the movie are presumably gas-powered, but I’d imagine an electric version would use in-hub electric wheel motors, an EDF as the jet engine, and continuous servos for steering, but I could be completely wrong here. Also, bonus points if you can get it to jump like in the movie!

@MakerMindset Год назад

I want to give you a suggestion to simplify the controls. You could install a motion/acceleration sensor that would lean the droid forward if it felt that the droid was accelerating forward or if it was going uphill. It could also lean the droid backward if it sensed that the droid was going downhill or if the droid was breaking. The same would go for the sideways motion. This would make the droid's motion look much more organic and would be one less control for you to worry about.

@frollard Год назад

The intelligent mixing seems a great route; Seems it would really benefit from some animator prowess; If mixing lean with direction of travel, using the concepts of anticipation and followthrough, getting the lean 'momentum' built before applying wheel power could add a lot of life to the motion. Same with braking; lean back anticipating the deceleration, then applying motor power. It would add significant latency so the controls would be tougher to pilot precisely but I'm sure like any system with predictable 'inertia' it could be smooth. Very very cool project, and looking foward to seeing the rest! I really want to build one now!

@pflagerquist3071 Год назад

Just some advice from someone who has used hobby meacanums in the past, you might want to add bearings to the rollers. This is because in my experience the added friction makes the wheels less accurate.

@tonym6937 Год назад

I like it a lot, but I believe the mecanum wheels are more normally used with the angled rollers swapped round the other way (they are on the B2). As you currently have it, the axis of the rollers (at the point where they contact the ground) are all aligned with the centre of the robot (like a needle roller thrust bearing) - this can allow the whole robot to freely rotate about its centre. If the wheels are swapped (i.e. swap left front with right front and left rear with right rear) so the 45deg rollers go in the other orientation (in relation to that wheel's axis), the roller axis at the points where they contact the ground will not be aligned with the robot centreline (they'll now be orientated tangentially to a circle) so they will be able to resist rotation about the robot's vertical axis.

You could put some scroll wheels on the sholders of your controller. Like how the Radiomaster Zorro transmitter is configured.

@JohnnyWednesday Год назад

Perhaps you could code the head so it always tilts in the opposite direction to the vector of travel, then 'catches' up to the vertical after a moment - same again for slowing down - it'll look great :D
