Link to this site strandbeest =Week0 Activities== The main issue with the expected Strandbeest model is first that it has to be able to rotate.By rotation we mean the movement of the first wheel on the left in relation to the others.the first foot on the left wheel must be able to move the second foot by nature of its attachments and also turn the wheel to its right.Earlier models found in storage seemed to all lack this basic idea.Also the strandbeest needs to be made of material strong enough to move under its own weight.


 * my task is to find a suitable motor capable of turning the strandbeest wheels so as to propel itself in motion.This will definitely be found in the fan of a hand held drier.

Compare actual work done to Task1
I was able to get a fan motor from a spoiled hand held vacuum cleaner i found in my home. This should be able to provide the lego parts with the torque we need to move our designed strandbeest.

Week1 Narrative
Upload photos to wikimedia. Upload video to youtube. Convert all spreadsheets, documents, and presentations to wiki format and create wiki subpage of your page for each of them. Link to them here in a narrative that tells a story. High light the problems (engineering problems) you had and how you solved them.
 * [|strandbeest lego parts]
 * The above link should show an example of theo jansen's design .they are the favorable design owing to the size and ease of getting all the necessary parts.
 * We currently lack a lego engine but we will definitely be able to make those parts rotate by the fan of the vacuum cleaner i provided.
 * we also suffer being a little behind in getting a perfectly moveable leg design but we are getting very close.

Week1 Peer Review
Q Chi helped with giving ideas and suggestions of what tools and materials(motors) we are going to attach to strandbeest. His ideas and the team members' ideas seemed have a lot in common and helped to make decisions more smoothly than expected and allowed us to prepare to go on to next phrase of our project.

Assign Task2
Record what you are planning on doing for the team during the weekend between week1 and week2 of the project here.
 * My main task was to work on the lego designs for the strandbeest foot as that was our main deterring factor.
 * Also was to seek out as many lego parts as i could find.The storage was lacking in some bolts that could hold the parts together.This was a general task for all the team members.

Compare actual work done to Task2
I was able to get just a few lego parts but nothing too significant to the project.The required fan engine we needed to make the strandbeest move was acquired instead.
 * I also came up with some new ideas but they all lacked mainly when it came to attachment of the different rows of feet

Week2 Narrative
we now had all the basic designs for the strandbeest which we collectively designed in class. What basically remains is the design on how we are going to put in the motor for the motion of the feet.
 * From the previous strandbeest designs, it is clearly seen that all movement is basically in the form of a wave running through. with this in mind, it is our prime goal at this time to make this motor sit perfectly and propel the strandbeest. A good picture an be seen from this video clip from youtube.

Assign Task3

 * Now that we are coming to a close for the project it is important that we finish all the basic designs for the placement of the motor.
 * The motor is to be made from the LEGO parts. It has been ordered and so we have to complete the build up on the parts before it arrives so we could simply attach it.[|strandbeest lego motor]
 * it is also necessary to get the arrangement of the cogs for which the motor's driving force could be transmitted to all the moving parts.

this was easily achieveable by setting a horizontal base in the middle of the new strandbeest design i was able to come up with.
 * I was able to come up with some bright ideas on how to work the strandbeest cogs. the pictures are shown below.
 * there was also the arrangement of the setting of the motor

Week3 Narrative

 * I was able to use the 123D software in the college to try drawing a digital image of the strandbeest model we were working on so as to see all the movable parts before doing it mechanically.
 * the feet will definitely have to move in opposite directions if the strandbeest is wanted to move forward.there was a problem with this because we are required to use just one motor to move the entire strandbeest.
 * to answer this issue, i came up with a suitable design which when hooked up to the cogs arranged in a particular fashion should be able to make the feet be propelled at different intervals of time such that one foot proceeds the other.
 * also there is the issue of holding four parts of the strandbeest four parts but which are require to still move. This was an issue because gluing it together was going to make it stiff.
 * T o answer this, after a lot of searching and from the 123D designs i saw that a four edged lego hinges held them in place just fine and also left for space for the parts to move.
 * Also to hold the shaking part section for the motor to sit on, i glued the parts together using epoxy.

Assign Task4

 * prepare the insertion of the motor if available.
 * test for the proper movement of the cogs so as to efficiently transfer the power of the motor.
 * Try all means to complete the project and document all our findings such as to help the next team continue from where we stopped.

Compare actual work done to Task4

 * We were able to come up with the cog arrangement for our strandbeest model.

Week4 Narrative
The cog arrangement which we came up with proved to be quite efficient for moving the strandbeest in the desired manner. An example of this kind of desired motion is shown in the video link below.
 * [|strandbeest movement]
 * With this design the power of the motor can be efficiently transfered to all the moveable feet shown in the pictures above.
