Possible improvements

ModiBotXForeArm3

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.

Delayed gratification

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.
