Step 13: Bolt covers

Cover all of the bolts with rubber bolt covers to give them a bit more traction.


<p>I know im a few years behind here but cool remains cool....and this is most certainly cool.....a very very simple and very clever idea.....a mechanical robot and not electronic ..I think you may be a genius....thank you.</p>
<p>if i use dc motor instead of this motor?</p><p>it is right to do.</p><p>Because when you remove controller from motor it will move continuously and dc motor is also moves continuously.</p>
<p>It would have to be a geared DC motor. A DC motor by itself probably won't have enough torque.</p>
<p>i have a 3 pin dpdt lever switch ...is there any way i can use it ???</p>
<p>Nope. This wont be able to reverse the voltage.</p>
<p>my dpdt lever swich has only 3 pins instead of 6 like yours ? is there any way i can still use it ? im doing this for my school project and im in a hurry....pls reply asap</p>
<p>I never post the &quot;I made it&quot; of this bot. I love so much this project!<br></p><p>http://www.instructables.com/id/Alternative-Design-of-Randofos-Walker-with-upcyc/</p>
<p>what sets of the dpdt?</p>
<p>hey admin how did u do the servos for direct drive can u explain me properly i can't understand the way wat u said?!</p>
Nice Robot, but I have a question regarding the servos motor. <br>I have modified it like said in the walkthrough, but my motor goes just one way, it doesn't go forth and back like it should? I haven't used a DPDT switch, because it is damn hard to find, so have just used a regular switch, is this the problem? I can get 2 SPDT switch, so maybe I have to try that... <br>Thanks in advance
I have now tried the 2 SPDT switches, and gotten the motor to go back and forth...but I have to press the switch every time I want to switch the way the motor goes. In the video the motor goes back and forth without pressing the switch, is that because of the switch I have used or have I done some other thing wrong?
does the CD toggles the lever switch?
thank you for join it, now i am motivated for build it..
its so amazing <br>i follow your great idea. thanks for share it :-)
awesome man...!!...it really..wrked..nd dat too on my first try..thnx..i ll remeber dis bot....forever !!
hey ! its shivam from delhi and i am also trying to make this one........but i cant find the servo motors as well as the DPDT lever switch........can u tell me from where did you find it?????????
i got one from an old rc toy. hope this helps and goodluck!
You will find servo's on ebay fairly regularly now - but old RC toys are also a good source.
elegant mechanism :)
I'm a bit confused. So because it's a DPDT switch wired to run backwards also, you don't use the switch to turn it off but to reverse the motion? Would the only way to turn it off be to take the batteries out?
Yes. The only way to turn it off is to remove the batteries. <br /> <br />The DPDT switch reverses the polarity of the power going to the motor. When the polarity is oriented one way (+ to -) the motor spins in one direction. When it is reversed (- to +) the motor spins in an opposite direction. The bot is basically changing its own motor direction.
Nice &amp; innovative idea!Can you please tell me can we use toy motors instead of servos as they are expensive! Thank You!
Yes. Just get 2 identical geared motors.
Is a toy motor and gear motor the same? Sorry I'm new to robotics!<br>
Nice work dude! Its pretty cool!
can u reply quickly because i need 4 Wednesday <br>
can i use a motor to replace the servo because in uae i can't find it<br>
very weel<br>
that is so cooooooooooooooooool<br> i like it very muuuuuuuuuuuuuuch
Continue giving us more instructables...........<br>
Soon. Very soon.
very good man!!!<br>
my servo has 3 wires and how can i convert them into 2 wires like seen in the pictures<br>
hi, does it matter if instead of a standard servo we used a continuos rotation one?
That should be fine.
how do i print the templates?
You should be able to open the eps with one of the image viewing programs on your computer. Then, just print it out using a normal computer printer (be careful not to re-size it)
where can we buy the servos motors??
I'm using Parallax motors. Try:<br /> <br /> <a href="http://Parallax.com">Parallax.com</a><br /> <a href="http://Jameco.com">Jameco.com</a><br /> <a href="http://Mouser.com ">Mouser.com </a><br /> <a href="http://Digikey.com">Digikey.com</a><br />
the thing is if we modify the servos for direct drive.<br>wont it block the handle of the telephone.?<br>
What do you mean?
no what i mean is ..<br>wont the bolts get hit by the arm of the telephone..<br>and could u pls tell me how does a modified servo work ..<br>as in how does it rotate exactly <br>thnk u
No, because the switch reverses the movement of the motor before it gets the chance to go that far.<br /> <br /> Basically, a servo is a geared motor with a controller board inside. When I modify it, I remove the controller board so that the motor becomes direct drive. In the materials step, I have a link to how to do this.<br /> <br />
thanks a lot for your help..<br>can u pass me the link cause i tried modifying and it was a great flop...<br>cheers<br>
Which type of servo motors are used here?<br>Can we use simple dc motors used in DVD,VCDs ?<br>
u can use the one found in the air conditioners..............you can it from an A/C service centre.........hope this helps.......
i was wondering could i glue two SPDT lever switches together and that means it will have 6 total leads and the cd can still press switch both ways? PLEASE HELP! thanks :) !
Yes, but it won't be as reliable. You would to carefully position them so they are both hit at once or you might risk shorting the circuit frequently. You should try to get a DPDT switch
