Introduction: Knex Simple Walker

Picture of Knex Simple Walker
This is a very simple waking machine I made. Its sturdy and reliable, and fun to watch as it crawls across the floor.

It also uses a small amount of pieces, and one of the more common motors.

Enjoy!


Step 1: Parts List

Picture of Parts List

This is the parts list. There are not many used.

Connectors
2 white
36 purple
10 yellow
8 green
14 red

Rods
2 red
23 yellow
10 blue
10 white
28 green

Miscellaneous
16 blue spacers
22 silver spacers
Other
1 Knex Powerpack (Short or long stringed, doesn't matter).

Step 2: Sides

Picture of Sides

These are the sides that rotate around the core.

1: Make this. Remember the green rods
2: Make this part as well. Make sure to get the spacers right
3: Close up...
4: Put the two together to get this
5: Make its twin. It is an exact mirror image
6: Put two red rods on one of the sides like this.

:-D

Step 3: Core

Picture of Core

This is the inner part of the walker that houses the motor.

1: Make this panel
2: Make another panel and put the rods on like so
3: That piece from another angle. Those are tan clips on blue rods
4: Slip the motor onto the panel like so
5: Put the other panel on and put two more tan caps on the blue rods at the top
6: Get these pieces ready
7: Put it through the white connector like so, and put the other spacer and red connector on the other side. Make sure that they are connected facing the same direction
8: It should look like this from above
9: Make make this attachment on the end. Pretty simple
10: Make another one on the other end
11: It should now look like this. Notice that all the reds are facing the same direction

Step 4: Assembley

Time to put the two bits together! This is easy. Make sure you have all the spacers in their right spots.

1: Take the side with the reds and position it with the core like so
2: Connect all the blue rods to the red connectors on the core
3: Close up
4: Put the other side on the same way
5: Connect The red rod going across like so

Whoop whoop, you are done!

Step 5: Usage

This is really easy. Just throw the switch and watch it go!

Cheers!

I made it and its awsome! but it went under a sheet and my cat pounced on it snaping the 2 main yellow rods :( but i made it again and it still worked like a charm!

Cool man! Thanks!

It is a good design for a walker but there are some problems

1) the moter cannot lift its own weight therefore the walker jams, i am having this issue and loads of other people are as well

I_am_Canadian (author)hunter9992011-05-01

Yes, some people seem to be having that same problem. I never had it, so I'm not too sure how to fix it... Make sure its built right and you've got fresh batteries in there.

hunter999 (author)2011-04-11

your piece count is wrong

I_am_Canadian (author)hunter9992011-05-01

I have do doubt that it is :-)

knexsuperbuilderfreak (author)2008-11-28

i bulit this and the motor cant lit it self

Be sure you have good batteries, and that you are not running it backwards

norton220 (author)I_am_Canadian2010-12-19

i got the same problem...decent motor and good batteries but it just strains, and goes nowhere...cool build although it was useless for my motor.

ok i think i wil do that motor tune up

aleceatsfood (author)2010-12-14

hmmm I made dual spiffs and now Im out of green rods? do I take one apart for this? maybe I'll think

Mine doesn't even work.... DOn't worry its just my motor....

paperninja (author)2008-11-27

I just got done making my new walker, it uses the same concept of this one only with a lotta gears and is very complicated. i will post a slideshow and maybe an instructable in the future. i am now currently working out the bugs of the design so it should be done by the end of thanksgiving break. it looks sorta like an AT-AT unit(for all you non-star wars fans)a linkhttp://www.nerf-herders-anonymous.net/images/RobotChickenStarWars_ATAT.jpg this one was from Robot Chicken star wars special.lol. i will see your comments in the future.

I_am_Canadian (author)paperninja2008-11-28

That sounds really cool! Pictures? S03lkill3r made a AT-AT and put a vid on youtube, its pretty cooL!

I'm gonna make an at-at too! it may be difficult but i think im up for it. :-)

mgaukrodger (author)smattman222010-08-06

smattman22 (author)I_am_Canadian2009-08-17

danbaha (author)2010-07-15

This is awesome! It is very piece efficient and it has a really interesting way of moving!

I_am_Canadian (author)danbaha2010-08-03

We built a variation of this robot integrating the PCS BRAIN to control it. Thought to share!

Wow! Thats incredible! I really like the way you mounted it. Video by any chance?

Yes. Should be up this weekend sometime.

Nice! Can't wait to see it!

Howdy,

Just posted a video: KNEX Simple Walker

It was a fun build.

TOCO (author)2008-12-24

I think your parts list needs to be changed. I gatered all of the parts you said and ran out of parts. I did build it and it is really cool.

I_am_Canadian (author)TOCO2008-12-24

What was I short of?

TOCO (author)I_am_Canadian2008-12-26

I counted more than 18 purple connectors.Unless you counted the full part when they are connected then you went too high. I know there was more but I dont remember. If it is still built you should check your parts list and maybe change it.

I_am_Canadian (author)TOCO2009-01-10

Fixed.

TOCO (author)I_am_Canadian2009-01-10

Thats great!

srhadaham (author)2008-12-10

I had that motor until recently. It started making a high pitched scream. I think its the motor casing but I'm not sure. Nice walker 5/5

Owenmon (author)srhadaham2008-12-21

ooh! mine two. i just opened it up and tightened some things up then put it back and it works just like new! And a little bit more faster >:)

Owenmon (author)Owenmon2008-12-21

it was doing that because it was on for a long period of time, thus doing......sumthin XD

Capt. Fat (author)srhadaham2008-12-19

The batteries were probaly dead, or there was to much friction

srhadaham (author)Capt. Fat2008-12-20

they were fully charged rechargeable batteries and I found out the problem was in fact the motor casing being squeezed.

I_am_Canadian (author)srhadaham2008-12-10

Thank you!
