The biobot was created with the idea of carrying a handyboard on top of it. Due to this it has a wide short body. It has four legs which were orginally made with bricks and beams. Now they use 'arms' (i like to call them rods) with tires on the end. I put tires on the end once I saw how much the legos slid on the desk top. The tires added a lot more friction and solved this problem - it will be interesting to see if the bot walks on carpet.

coming in week 5


Week 1

Original Concept: I have decided to model my robot after the nara cricket, the link below is a video of it walking. I choose this bug mainly because I wanted to use a 6 legged insect. From my searches it seems that many different bio-inspired lego robots have been modeled after insects.

Week 2

I have been trying to build a six-legged robot and it is getting pretty large, so I may decide to knock it down to four legs. I orginially wanted to use six legs because I thought it would be easier to balance when walking, but now I hope I can manage to do that with just four legs.
Also, I found a researched lego motors since my kit did not have any. I found a site (link below) with different motors including the one that is in our kit. This site just tells you about them, but I have also found places to purchase some of them (ranging from $20-30.) If anyone needs motors (or has extra motors) please let me know so we can figure out if we need to place an order asap.

Week 3

This week I worked more on the physcial model. It is complete except for the parts that I don't have. I obtained a second motor and have sent out emails to see if people have the parts I need. Specifically, I need the lego peices with the wires so that I can connect my motors to the batteries.
I also spent time play with IDEAS what I have figured out so far:


Open the IDEAS 12 program The model path should be F:\scratch\LegoPartsLibr.mf1, Click OK Click OK twice, then dismiss
Save As something else before you make any chanages - there will not be enough room on the F drive so you will have to change the location. It is probably best to bring your own storage.
Click on the down arrow next to the Manage Bins icon (two red triangles on opposite corners with square in the middle) and select Get This will bring you to a list of the part, click the one you want and hit OK (will close the window) or Apply (adds the part but does not close the window)
When you add a part it will be removed from the list; if you do not want it any longer you can "put it away", do not delete it
The F keys allow you to change your view (hold them and move the mouse)
F1 – translate
F2 – zoom
F3 – rotation

All the items will come up in the middle of the screen to move them Click the move icon (two squares representing a translation) and follow the prompts in the lower right corner - more detail below.

  1. Select the part (left click)
  2. Right Click the part and go to done – a window will pop up
#* If you select Move To you have to select another part to move it to
#* If you select Slide on screen, you can click and drag it to another location on the screen
#* If you select copy sw you can make copies – enter the number of copies you want and then click and drag

I have not been able to get two pieces to connect to each other even when trying to use the move align options.

Week 4

I completed building my physcial robot, but have not been able to test it. I plan to get the wires I need to hook the motors up to the batteries in class today. I also played with IDEAs more, but have not actually started building my virtual model. I am going to explore more tutorials before next week so that I can start to create my viruttal model.
