*) thank u lawrence :)

New Alternative

New Mechanic Structure Alternative

2nd Model

hexagon motor structure

using angle wheel

we will combine this hexagon with our 1st model

to create a movement like a jellyfish leg.

LED testing

1st model

We plan to put LED on the tip of the tentacle.

A. Tentacles with same length

B. Tentacles with different length

The structure

A. with 1 wheel

B. with 2 wheels

A. 1 wheel

B. 2 wheels

Tentacle color choice

Exploration

S I T E

Tung Wah Group of Hospital

Hong Kong

M A T E R I A L

(1) segmented plastic straw

(2)

steel

suspension

(3) wire protection tube

M E C H A N I C A L _ S T R U C T U R E _ 0 1

with material 01

with material 03

M E C H A N I C A L _ S T R U C T U R E _ 0 2

Irregular path generates motivation and the legs will move up and down.

FEEDBACK :

1. Material 01, M Structure 01 combine with irregular straight wheel (A1)

2. Figure out how the growth process (longer sitting time)

3. Make a diagram of the movement in the field
