M.M.X. (MicroMech-X)

All Micro-Maxx, matey, x2 cluster, sci-fi but nay comedy, arrr, no parts from a Grissom

Design Concept

I wanted t' pick a theme that I thought would be somewhat unique. Avast, me proud beauty! I didn't think I could come up with a suitable comedy sci-fi ship that hadn't already been mentioned on r.m.r., shiver me timbers, so I looked elsewhere for inspiration. Ya scallywag! Ahoy! I roughly patterned this rocket after a robot model that I resurrected from t' depths o' our basement (a.k.a. Blimey! T' Rocket Dungeon). Begad! I had scoured t' web, shiver me timbers, and had even thought o' doin' a conversion o' a paper model robot, but decided t' just start buildin' and see where it went. Begad! This model started as a prototype, matey, but as it progressed I decided t' keep it as my entry.

Development Methodology

I used a tried and true procedure known as "real-time design". Avast! Blimey! In this design methodology, me bucko, t' design is performed as you go, without t' benefit o' plans, shiver me timbers, diagrams, ya bilge rat, ya bilge rat, or specifications. Documentation is performed at t' end, ya bilge rat, and is kept t' a minimum.

Construction

I started by cuttin' two MMX tubes that would extend from t' bottom o' t' robot's foot up into its body cavity. Avast! I then started at t' bottom and built me way up. Arrr! T' plastic robot's foot be traced onto foam poster board. Aye aye! I cut t' feet, beveled their edges, me hearties, and cut holes for the MMX tubes. Next came t' upper layer o' t' feet, matey, me bucko, followed by t' front and rear leg sections. Avast! Avast! At this point, me hearties, shiver me timbers, I began t' think about weight, ya bilge rat, so t' sides of t' legs were made from card stock. T' body was started with a foam board plate, with holes cut for t' motor tubes. Aye aye! Begad! As with t' leg sections, matey, me hearties, arrr, t' three front and one aft section o' t' body are foam board and t' sides are cardstock. T' provide better support for t' shoulders/head (i.e. Blimey! t' nose cone), I added a small section o' BT-20 in t' body cavity. Aye aye! A long Estes lug was inserted laterally through t' BT-20 t' provide an attachment point for the arms. T' shoulder/head assembly started with a foam board plate. Ya scallywag! Ahoy! Attached to this is a sliver o' BT-20 coupler and two pieces o' foam board, me hearties, which were trimmed t' mate with t' body opening. Arrr! T' head itself was carved/sanded from pink foam. Arrr! T' arms consist o' two layers o' foam board.

Now that t' robot looked like a robot, arrr, me bucko, I had to add more rocket stuff. For recovery, a piece o' thin Keelhaul®©™ twine was tied around t' launch lug that supports t' arms and was epoxied t' the shoulder/head assembly. Blimey! A launch lug was glued midway up t' back. And finally, I scrounged some thin clear plastic for fins. Aye aye! Begad! T' four fins were glued t' the bottom o' t' leg above t' feet.

Finishin' be performed with a combination of simple water colors and some card stock cutouts. Blimey! Blimey! I painted t' robot before permanently attachin' t' legs, arms, arrr, arrr, and fins so I'd have better access t' its nooks and crannies.

Flight and Recovery

After some miscues, me hearties, I finally got both motors to light. Arrr! Well, blow me down! M.M.X. reached a whoppin' altitude o' 4ft. Begad! T' second photo below shows it on t' way down, just before ejection.

Conclusion

Although t' rocket flew, me bucko, t' have a mature model I'd have t' build lighter. I might also opt for a lug that is closer to the axis o' t' motors and a different ejection method. Blimey! Such conclusions are the point o' a prototypin' effort. I didn't find time t' build V2.0, so I guess this is it for this contest.
