Arming Up

I got 2 pairs of boxing gloves at a local thriftstore.  Enough for a pair of fighting bots I guess :P

Started making the various bits out of metal:

Workflow is a bit different than carboard/papercraft.  You start out tracing from the paper pattern onto the sheet, but instead of directly cutting it out you just  score the metal with a knife and then tear along the seam.  It quite satisfying to rip metal into all the funny little patterns.

Secured to the frame with bolts and some funky inner PVC framing that seemed simple but took up most of an afternoon.

 I put an outer sheathing on the elbow cables so they have more protection and look pretty cool.  I have no idea where the sheathing came from: found about a hundred feet of it all curled up in the bushes behind the house.

The "hands" in the glove is just a 2x4 slid into it, bolted onto the PVC frame.

The shoulders were quite an experience, using about 40 rivets each.  I'm banking on the duct tape wearing off.  Or I'm gonna need a wire brush.

Mounted in various ways (aka a stap, a floating ball and socket joint) the shoulders are looking interesting.  Using some fun noodles to give an interesting shape and act as a cushion from the projected jiggling the shoulders are gonna experience.

On a separate thrift store trip I got a skull and sparring helmet. Every 'bot needs a head, right?

Spoopy scary.

First Time Suiting Up

Have everything together to try it on for size:

A few things appear to me right off the bat:

- Seat is unstable: perched on 3 posts wasn't my brightest idea.
-With such a narrow base, the stasis dock can tip backwards easily, especially with a loaded boom arm
- The step ladder is good if someone wants to try out the arms (e.g. exhibition) but for a full suit-up a step built into the stasis dock base would be handy.

Stasis Docks and broken feet.

Since spring is here, my van has finally defrosted from its snow bank.  I went on a supply run to get some lumber and PVC for a new stasis dock.

There are four casters on each corner.  The front two swivel, while the back two do not but lock to keep the unit from sliding away when suiting up.

An adjustable boom arm is useful making a variable height for suiting up.  Note: adjustment of the boom arm under load is not recommended.

Wrestled the torso onto the stasis dock.  Spent a good few hours trying to find the winch and hook from the first stasis dock.  Turns out they were hanging on a the coatrack near the door behind an extension cord and garden hose.

The feet broke up in the last video.  RIP feet.  The mech has been de-feeted before it has even fought!

So I've come up with a simple, robust design.

And reinforced it.

Stay tuned for a video testing out the stasis dock!

Engines, Feets and Hands

 Been fiddling around with a snowblower engine.  Turns out a crankcase has a little valve to make a low-pressure system under the piston so it's easier for it to move up and down.  Without a sealed crankcase, there is too much pressure and the engine can't fully turn over.  So you either re-seal it (very hard to do) or get a new crankcase.  I tried some welding putty, but I guess it isn't airtight.  Since on this model the crankcase is attached to the engine block you can imagine where this leaves me.

 But, fiddling around with the engine has given me an idea for future mecha experiments: mainly on the powered variety.  All hush hush, you know.

Did some experimenting with foot patterns.  Very fancy (and Dutch!) but it doesn't seem very steady.

 So I went the simple route:

 In the meantime I also printed some revised hand parts.  Much more stable and rubber bands!

Torso Armor

Just whipped up a quick & easy design for the chest piece.

Forseeable challenges would be riveting along the curve (requiring multiple small brackets/tabs) and mounting the head so the chestpiece can swing up.

Bunjee Ankles

Can't find a compression spring that fits the bike suspension pistons and has the weight rating I need. So I decided to mod it into an expansion/compression stabilizing system. AKA many bungee cords.

I can balance on one foot now rather easily. No proof though: temp dropped and I don't wanna go out in my cold garage. Bad enough I gotta wrestle with my snowblower to keep it from shaking apart :D

Also whipped up a quick covering. Tempted to add in a few more curves now I'm getting the hang of freeforming stuff.

Arm Range Test

Weather warmed up enough so I could flail about with my giant robot arms.  Nifty.

Pilot suit & Greebles

Worked on the pilot suit a bit. No digital templates, just winged it.  Foam matting is surprisingly good at absorbing an impact.  At least when I was punching myself anyway.

Sketched out a template:

Checking out the orientation of the moobs

Houston, we have moobs!

What to do about the back?

This I guess:

Front is looking nifty too:

Probably gonna make a small vid next weekend wearing the Arm module and the pilot suit.

Added some greebles to the back armor:

Back Design

Sub-Zero temps means my garage isn't much warmer so I've moved some of my operations indoors. Designed some back armor type stuff:

And built it. 18" ruler for scale.

Quick render of how it will look with the arms.
