Character Design Template for ModiBot Mo figure kit
Evey great story is built upon the foundation of great characters, but memorable characters don’t just grow on trees, they are crafted to tell that specific story that is held within them. The prospect of their personal growth and subsequent adventures are hidden there just below the surface, built into their DNA.
Character design is something that is learned over time and isn’t just about how a character looks, signature gear or what traits they display under pressure. To find a place in your heart, a character needs to take on a life of their own. A life which might in fact be much more exotic and vibrant than the life of their own creator.
At its core, character design is about making smart decisions early in the process and continuing to ‘taste’ those decisions and how they play our across the landscape of your story. ModiBot was made as a tool for designers and storytellers to craft their own characters and stories on top of.
I’ve attached below a simple tool, a design template, to help you take the first steps in crafting your own epic adventure starring a character of your own design. The template isn’t the answer, like ModiBot it is just a tool to help you play with and express your own unique ideas. Think about like a playground for your ideas.
So, scribble, doodle, tinker, draw over top of Mo, and scratch out what you don’t like. Do it a million times. Its not meant to be perfect. Its meant to be a process. Have fun with it!

Visual FX for stopmotion
This short called ‘Dark Soul’ is from newcomer Tony Booth a.k.a Flash Flanker.
What I love about Tony’s approach here is that he instantly starts out creating a feeling that the world is off-kilter. The flashing imagery and severe lighting make the scenes fell more creepy even though they are well lit.
What really stands out for me is that he’s really working to take risks and experiment with the visual FX. The cuts between the other-dimensional accessories and the use of different materials to convey the slime flying through the air and finally enveloping its victim feels sick and claustrophobic.
Great job, Tony. I’m looking forward to seeing what you come up with next.
Green screen animation technique
This clip below from Mauricio Lozano features several higher-level animation techniques.
The first is filming against a green screen. This compositing technique allows you to crop out the background and replace the it with a photograph or 3d modeled scene. As you can see from the final composite, this technique is great for saving on the time of building elaborate sets allowing you to drop your characters into more fantastical settings.
The second technique build upon the first. Mauricio is using green ModiBot parts to construct his own posing rig. This rig allow the animator to create the illusion of the figure floating in the air during acrobatics or effects-based sequences. This type of rig is pretty versatile and can be attached to the walls or floor of the set.
The final step in his process is to composite the scene in software like Adobe After Effects, but some effects can be achieved using simpler editors like iMovie. The clip turned out great and we’re excited to see more examples of Mauricio’s work.
We’ll be speaking about ModiBot, the role of Making and guerrilla product development in the current ‘free agent’ economy. Come build some ‘bots at the conference or bring the kids and come see us at Bay Area Maker Faire on May 18th and 19th!
Big Balls. That’s a problem.
Another round of parts. This time I upped the ball size to create more tension in the joint. That definitely worked, maybe a bit too well, so I’m going to bring the ball back down a bit. The one nice and unexpected side effect of the bigger ball is that as the grit wears out of the joint faster, but it still keeps a nice amount of tension. The ball becomes shiny and, I’m guessing, also wears the interior of the socket down
Let’s see. What’s new in the pics? The arms have the new cruciform post design to minimize the material usage. Which seem to still be fairly robust. This nylon material from Shapeways is pretty nice. I haven’t had any breakage so far. Maybe I should try to break something just to get a feel for the amount of pressure it takes.
The other new thing is the the newly designed forearms. These are Xevoz-compatible (the future ‘ModiBotX’ body), but also have a smaller wall thickness on the wrist socket. The hands shown are from last round and still have the smaller ball (and shorter shaft design that didn’t work or look as well on the original forearms with the larger sockets. The tapered look is great and the wall thickness doesn’t seem to creating a breakage problem. Something to pay attention to over time.
The only other thing is the new ‘X’ cuts in the ball. These are intended to create some ‘give’ in the ball and seem to be doing their job. I’m somewhat wondering if this design will cause more wear in the joint. I’m prepared with a couple other options if this becomes a problem.
The posability seems pretty damn good. I’m getting a lot of travel out of the elbows. Much better than many of the ball joint figs on the market (it helps that he’s so skinny). I’m not quite sold on the current ankle design, but it mostly seems okay.
I guess the next phase is to start to assemble an entire kit. I’m going to push farther to reduce the material in the figure. Maybe cut some material out of the sockets with a pass-through and try the cruciform design on the other parts to see if they maintain their integrity. The cruciform is a bit ugly, but my goal is to get an entire figure down to $10 cost of material from Shapeways. I think I have a long way to go. The big shift will be to modify all the parts so I have a full Modibot Core body kit and a full ModiBotX body.
Finished a knife the other night. Pretty pleased with how it turned out, but… I just put it in context to the figure. Pretty damn big.
Sooo, I suppose its a bit more like an Appleseed tactical ‘sword’ or machete at this point. Still had fun doing it.
Since we’re running with this whole ‘constant beta’ mentality that is being discussed a lot in the start-up world, here’s a few new updated parts. I’ve already shifted many around, taken some down and hopefully made the system better and robust at every turn. Kaizen has worked out pretty well for the Japanese, right?
I built up the balls a bit and redesigned my compliance slots in the ball to see if they add anything. The sockets tend to flex to create compliance, but I wanted to see if this makes any difference. After playing with all the parts tonight, i think the new ball size might be too large, but we’ll see. Parts should be here on Dec 2nd or so.
What else? Oh, yeah, material efficiency. I cut a couple parts down a bit to see if making a cruciform cross section makes the shafts less sturdy. K’NEX use a cruciform shaft, so I think its worth the try. We’re probably saving pennies, but everything helps.
So, in addition to some new upper arms, torso and hip, I redesigned a forearm. Mostly because they were just too damn ugly, but the added bonus was that I cut a sizable amount of material out of the design. I also created a very small, thin-walled socket for the wrist. Its pretty teeny, but hopefully still robust. When they come in, I may try to tilt the socket a bit more to let the wrist bend more naturally. I moved the socket on the feet and you can see from my last post that the feet actually have a pretty good amount of travel. I’m pretty pleased with the new design, now I need to work it into the ‘diamond’ configuration. I’m guessing it won’t be as pretty as this design.
In the product world, it takes a long time to get product to shelf, but you are trying to put so many items through the pipeline that you don’t have a lot of time to ‘sit around’ waiting for something to show up. I got my 3rd round of parts in the mail today. Once I started designing the parts and working up a library of baseline components, it started to get easier.
After a lot of late nights (after the kids went to bed), I got a full figures worth of parts (in model form anyway). Great, right? Yeah, but by that point, I’d fallen behind on posts, my first parts hadn’t come in yet and the whole thing started getting nebulous. I’m being dramatic of course, but its sort of about our relationships to stuff, atoms, brick and mortal- real world stuff. I had a full figure in captured via screen grab in Rhino- fun to show around to my son or supportive friends, but it just wasn’t going to be the same until I had all the parts in hand.
Today is that day. Holy smokes! I forgot what it was like to have ‘first shots’ in your hand. Obviously, I’ve posted about the parts and the fit and finish of the material, etc. But today, I actually had a product in my hand. Something I could move around and pose and really understand the proportion and personality of what I’d created and assembled. Its a feeling that you don’t get everyday, or at least maybe its one you become accustomed to over time. Each subsequent, item becomes a little more mundane out of familiarity until it all blends together. The big difference here is that its something I did myself. I didn’t need a staff of designers, engineers, marketers, salesmen, huffing and puffing about why it doesn’t fit the market, or the brand portfolio, or won’t pass safety. This once, I’m just swimming in good vibes and the playful optimism, enjoying a job well-done and a blurry glimpse at what might be on the horizon.
So! Back on track. The one part that I have ordered in what I think is the right material is the torso. Its the ‘polished’ variant of the Shapeways strong and flexible option. I think it only comes in white and black, but I’m going to try to order one whole figure in that material to see how it all fit together. All the other parts pictured are the basic white or unpolished option- which is much grittier than the polished. The grit creates a decent amount of friction in the joint, so the figure will actually stand. All that variation of the surfaces gives me a tight fit. But,… The ball joints for the ‘polished’ torso part have smaller balls and much less friction. To friction or not to friction is an important question- especially when a protofigure is $30 a pop. The polished part is pretty nice, though.
I’m anxious to get the basic figure debugged and then opening it up for sale in a Shapeways shop. In the meantime, I’ll try a few on Ponoko and get a few made on a MakerBot to see the relative benefits of each. Then, on to outfitting this guy to see how far I can take this customizable figure concept. I’ve still got a good amount of stuff up my sleeve. Onward.
So, I finally got my first batch of parts, more than a week past my scheduled delivery. It was really exciting to open the box. I had no idea what to expect.
The parts were three pairs of upper arms shot in two different materials. It was pretty apparent which material to move forward in, especially since I broke one of the black sockets without even applying much pressure.
Surprisingly, the hi-detail prints, which are the more expensive choice, are actually less detailed than the ‘strong and flexible’ plastic. Since I had already ordered more parts, I got extremely lucky that I selected the ‘strong and flexible’ over the ‘detail’ plastic stock. The strong and flexible stock seems to be a styrene of some sort. For ball joints that need a certain amount of flex and grab, it seems to work perfectly.
As far as the function, the tolerances of parts seem pretty much without too much distortion. There seems to be a bit of shrink built into the process. My ball joints are measuring at 5.9 mm instead of the six I spec’d. I can also see that I need to make the balls a bit larger to stretch the socket a bit, which seems to make for a better fit. Next round will build a larger ball.
Oddly enough, my next order cam just two days after the first even though they were order two weeks apart. As disappointed as I was that my first order was crazy late, it was spectacular to have more parts in hand to compare to the first batch.
The second batch consisted of two torsos- one with a Xevoz-compatible square socket arrangement and another with the squares at tilted at a 45 degree angle (more on why that might work better in the future). I also had a Xevoz-compatible forearm set-up and another with the tilted square plug. I also tried a new set of upper arms with a through hole in the ball socket to minimize the material usage. The open socket might work with a thicker wall, but in this round I also reduced the wall thickness on every socket, as well. The socket just doesn’t have enough material for a robust snap.
I order several different colors to see how much variation there is between formulations, granularity of the print and the saturation of the various colors. Its likely an optical illusion, but the white does seem to have the cleanest print of them all. I like the two colors- red and a ‘cornflower’ blue. Even the gray of the torso part is decent but they all seem to be much more granular than the white. I’ll continue to order in white for now. It seems to be the better material.
For a bit of fun, I’ve started out with a few Xevoz-compatible parts- 4mm peg holes, 6mm ball joints. Modibot itself will continue to evolve, but for certain it will be founded in a ball and socket system (connector sizes TBD).
My overall goal is to create a very minimalist system to start and then develop a broader range of add-on accessories that will snap on to flesh out the minimalist chassis. I’ll testing how robust the nap system will be if I take it down to a 5 mm ball and 3.5mm peg/hole.
Here are a few of the additional parts. No the prettiest, but functional.
