Life, uh… finds a way…

Parts List:

Missile Launcher – Dragon Mountain Design (x2)

Helpful Tools:

3D Printer (or printing service capable of using flexible materials)

SUPERTite Multi-Grab 360 (Switching to this adhesive from E6000 as it is less of a toxic hazard)

**Also, if you’ve been looking to create something with ball/socket joints and like what I’ve started here, or if you need to make adjustments to the joints for your preferred fit, you can download the Fusion 360 file HERE.**

2. Blasters

Press-fit missile launchers into RK-BlasterBall as shown (x2). Use a little glue if necessary.

3. Arms

Press RK-ArmPin into RK-LeftArm and RK-RightArm as shown.

Press the arm assemblies into the corresponding holes of RK-BellyPanel. When assembling, make sure to orient the RK-ArmPin parts so that the snaps exert their force parallel to the printing layers. Forcing them in perpendicular may cause delamination of the part in that area.

4. Shoulders

Fit DMD-Socket into RK-Shoulders (x2) as shown.

Insert the shoulder assembly into the belly panel assembly as shown. Parts will snap together when fully assembled.

Using a back-and-forth rotational motion while applying force inward, fit the blaster ball into the socket of the shoulder assembly (x2).

5. Hips

Press-fit DMD-Ball into RK-Hips as shown (x2). Use a little glue if necessary.

Press-fit RK-Ribs into the assembly as shown. Use a little glue if necessary.

Press-fit the hip assembly into the shoulder assembly as shown. Use a little glue if necessary.

6. Backside

Press-fit RK-Spine into RK-Backside as shown. Use a little glue if necessary.

Press-fit the backside assembly into the hip and shoulder assembly as shown. Use a little glue if necessary.

Press-fit DMD-Ball into the backside assembly as shown. Use a little glue if necessary.

Attach RK-BackPanel to the pins of RK-Backside and ensure it can open and close securely.

7. Legs

Fit DMD-Socket into both sides of RK-Leg (x2).

Slide RK-UpperLegCover onto one side of the leg assembly until it snaps into place (x2). Legs should mirror each other.

Slide RK-LowerLegCover onto the opposite side of the leg assembly until it snaps into place (x2).

Using a back-and-forth rotational motion while applying force downward, attach the leg assemblies to RK-Foot (x2).

Using a back-and-forth rotational motion while applying force together, connect the leg assemblies to the hip assembly as shown (x2).

8. Tail

Press fit DMD-Ball into RK-TailLink (x2). Use a little glue if necessary.

Fit DMD-Socket into the tail assembly as shown (x2).

Slide RK-TailCover over the tail assembly until it snaps into place (x2).

Using a back-and-forth rotational motion while applying force together, connect the tail pieces together and to the backside assembly as shown.

9. Head

Press-fit RK-Eyes into RK-HeadAdapter as shown.

Fit DMD-Socket into the head assembly as shown.

Slide RK-Head over the head assembly until it snaps into place.

Attach RK-Jaw to the head assembly as shown. Jaw will be able to hold three positions if assembled correctly.

Press-fit DMD-Ball into the shoulder assembly as shown. Use a little glue if necessary.

Using a back-and-forth rotational motion while applying force together, connect the head assembly to the rest of the assembly as shown.

10. Dominate

Unleash your RoboKitty and vanquish all those who would oppose you!

Yeah, About That Name…

I realize it makes zero sense without context, so here’s the story:

When my daughter was a year and a half, every time we’d be in the toy aisles of Target, she’d gravitate toward this roaring and chomping T-Rex toy, plunk down in the aisle, and play with it. Obviously we got it for her that Christmas.

She named this ferocious dino “Kitty” and it was her baby.

No, I’m serious. She’d feed her, change her diaper, rock her to calm her down when she was upset, and put her to bed. This only increased a year later when we explained to her that she’d be a big sister.

More time has passed, and now that my son is around the same age, I knew I needed to get moving on this project so that he can join in the fun with another Kitty and they can play together with both. So far it’s working… I think.

My daughter loves the fact that she has a Kitty AND a RoboKitty, and my son gets the biggest grin on his face and roars whenever he opens RoboKitty’s mouth.

It gives me the greatest feeling.
