Write problem/project Goal
My project goal is to design a functioning Strandbeest with teammates out of the cardboard and other easily available materials.

My First Task
I will look up at previous projects tutorials and designs to see from where to start. Also I will make a design to build a strandBeest crankshaft.

Summary of actual work over first weekend
I tried to make a piece of crank shaft from LEGO's.

Week1 Narrative
I was planed to make a crank shaft from the LEGO's parts, and over the week end I watched and read some documentation to get an idea where to start. I started to make a crank shaft from LEGO'S part. From some of the parts, that I got from previous group, I tried to make a piece of crank shaft which has been shown in pictures above.

My Second Task
My second task is to get more LEGO's pieces and make crank shaft pieces at 120 degrees apart.

Summary of actual work over second weekend
On the second week end I made a crank shaft made from the Lego's pieces. Below are some pictures of my work which demonstrate, how to make a crank shaft from Lego's pieces.

Week2 Narrative
During this week I built a prototype crankshaft of the form and structure of the crankshaft to be build. This prototype served as a method for understanding the placement and position of the crankshaft pieces. After analyzing the reason as to why the crankshaft wouldn't work I realized that the pieces I use were straight pieces, therefore when moved at different angles their center will change with the piece. What I did was to link two LEGO pieces together and set them at 120 degrees, like this allowing the addition of a third piece without changing the center of the crankshaft. To make an angle of 120 degree I used an edge of the wood, which were cut at 120 degrees. While looking for other pieces I came across a new piece that i haven't seen before and I believe it would be very beneficial in reducing the general weight of the crankshaft.

My Third task
My third task is to complete my crank shaft and design some legs which can best fit and easily mobilize in my crank shaft.

Summary of actual work over third weekend
My previous crank shaft looked good, but the problem with that crank shaft was how to connect the legs with it, and how they can mobilize easily on it. I started again from the beginning, and this time I made a crank shaft which has some legos bearings on it. These bearings can be seen in the picture.

Week3 Narrative
My previous crank shaft looked good, but the problem with that crank shaft was how to connect the legs with it, and how they can mobilize easily on it. I started again from the beginning, and this time I made a crank shaft which has some legos bearings on it. These bearings can be seen in the picture. These bearings are very use full because I can attach the legs on it easily. I made four legs from the legos, and attached them together at 120 degrees, and made a complete crank shaft. It can be seen below in the picture. After making the central crank shaft I made a rectangular frame for the crank shaft. For the frame I took two 6.50 cm bares which had eleven holes with the diameter of 4.80 mm. I put the crank-shaft's axle in the middle hole. After that I measured the length of crank shaft which is approximately 42 cm, and I took two plastic rods with the length of 45 cm. From the ends of these plastic rods I turned them down to 4.80 mm so they can fit in the holes of 6.50 cm long bars.

My Fourth task
On the final week of the project I am going to design and make a leg which can best fit in my crank shaft. Further more I am also going to find some online links where I can find more legos parts which are used in this project.
