Step 9: Glue Down the Components

Use hot glue or epoxy to secure the bump switch and the motors to the mouse chassis. I used a combination of superglue and hot glue to hold in the bump switch and hot glue on the motors. Make sure the angle of the motors are roughly equal and extend down enough to raise the front of the mouse slightly off of the ground.
<p>its a very raw version, but it works :)</p>
<p>please give me a video making !!!</p>
I finished my Mousebot over the weekend. It works perfectly thanks to the correct schematic at: <a rel="nofollow" href="http://streettech.com/robotbook/circuitMousey.html.">http://streettech.com/robotbook/circuitMousey.html.</a> The kids and cat are impressed. I made a rubber bumper by cutting a rubber washer in half and hot glueing it around the front of the mouse over the switch. Several mechanical challenges. The case doesn't close completely so I'm holding it together with rubber bands. And the back end is so battery heavy that it often can't get enough torque to back up. And it likes to circle to the left which is actually a nice feature - less mouse chasing.<br/><br/>I learned a lot from this project and it really got my interest up in BEAM bots.<br/>
this schematic https://cdn.instructables.com/FFS/NUTG/SRBEUXWQNIO/FFSNUTGSRBEUXWQNIO.LARGE.jpg is better that the first init pliiiz repliie <br>
<p>thank you</p>
<p>awesome stuff .. gonna try that on my mouse</p>
<p>yep great</p>
<p>how many is it the DC dynamo size? and the size of relay? Please help :)</p>
All I have is a LM358n. Will this work?&nbsp;
<p>yes it should...</p>
<p>This is a textbook quality Instructable !! Clear and concise - PERFECT!</p><p>Thanks!!</p>
<p>Thanx! Going to make another now :P</p>
<p>This is a really neat project. Where can I get all of these things?</p>
<p>RIP Donor mouse.</p>
<br> Hey, I just finished mine but unfortunately it does not work. Don't know what I'm doing wrong... One motor spins real fast &amp; the other spins really slow.<br> <br> Thought I had done some wiring mistake the first time &amp; re-wired the whole thing again, but still the same issue.<br> <br> Any guess's, adding in a pic of what I have as if now though.<br> <br> <br>
hey dude i had the sam problem; once he had a circuit here and its different from the stuff he tells u; search for the circuit, it might be in the pdf
put a 200 ohms resistor 1 to 8 of the lm386
Got this working a few weeks back. I had some of the problems other people have had, mainly one motor getting more power than the other. I found the bot worked perfectly in pitch black with one VERY bright light. It moves extremely quickly and the batteries don’t seem to last to long. It’s lots of fun!
wht have u used bro https://cdn.instructables.com/FFS/NUTG/SRBEUXWQNIO/FFSNUTGSRBEUXWQNIO.LARGE.jpg
+ is always the longer wire but look inside the actual thing and the smaller one is the anode (+) the larger one above it is the cathode (-) hope that helps<br />
which one is correct dude https://cdn.instructables.com/FFS/NUTG/SRBEUXWQNIO/FFSNUTGSRBEUXWQNIO.LARGE.jpg <br>
thankyou very very very very very very much!
can i use a 12vdc relay, or can i use two relays?
The number on the relay is telling you how many volts are required to trigger the switch by sending the voltage through a coil between two pins. If your robot uses a 9VDC battery, then you will need a relay that can be triggered by about 5 or 6 VDC. A standard 9V battery won't trigger a 12VDC relay. <br> <br>You want one Double Pole Double Throw (DPDT) relay rated for 5VDC or two Single Pole Double Through (SPDT) relays rated for 5VDC. <br> <br> <br>You can purchase and appropriate 5V DPDT relay from Solarbotics or just read more about how they work on their site. http://solarbotics.com/products/re1/ <br> <br>Hope this helps. <br> <br> <br>Sincerely, <br>Christin Boyd <br>http://robotfun.wordpress.com

Wow, lots of comments here since I last was on. I have finished building my mousebot. Here are some pictures: I used Radio Shack's LM386N op-amp and it seems to be doing fine. I had to order my relay online. The best deal I could find was from futurlec.com. They had the exact part for $2. Worked great. Hecbot, regarding the LED. Did you wire the sensitivity boosting circuit with the revised schematic on streettech.com? I used that schematic and my LED lights up. The sensitivity of the IR beams seems to be pretty good too. I would think that there may be a problem in your circuit, although it may not have one. Check to make sure that the negative and positive are in the right spots, because the LED won't work otherwise. Stephen: that stinks that your bump switch isn't working. Did you check the poles on the switch to make sure that you didn't break off the wrong one. Out of the two side poles only one is connected to the switch, and that is the one that should be connected to the cap and the timer resistor. Other than that, I would just take a good look over the schematic and compare it to your circuit. I know that a few times I had some miswirings and they can drive you crazy! Also, I had a relatively small mouse and I had to cram it all in the case. My motors are also larger than normal, I took them off of an old xMod RC car. This has a been a fun project! Erich
have u yoused that http://streettech.com/robotbook/circuitMousey.html ?

I found through some testing that putting a resistor across the gain (Pins 1 and 8) of the OpAmp chip (LM386) rather than just soldering them together gave me better results. Every robot will be a little different because we're all using different IR emitters or IR LEDs in our bots. <br> <br> <br>You can read about my experiments and how I determined that a 200 Ohm resistor resulted in my mouse moving in the straightest line on my blog. <br> <br>http://robotfun.wordpress.com <br> <br>-Christin Boyd
and also about the lm386 please help cuz i think that i fried them !!
im really impressed by your ideas !!! but i want ask you a question how can we know that IR light emitter works and not fired please help
i just finished making this and it doesn't work! i have no idea what i am doing wrong, it could be anything! <br>PLEASE HELP ME!!!!!!!!!!!<br>maybe like a schematic of something like that.<br> please respond ASAP! i am doing this for a science fair project and its due Monday!!!!! :0
......................or a circuit?
never mind i found something<br>
wht waz your pbobleme brother because i also finished the project but it doesnt work ! please help me brother and i will be really thankfulllll ...thnx
i've made the test in the bread bord when i on the toggle switch the motors run normally but the Led is still off .and when i put the light on the sensor they didn't work and also the bump switch didn't work :( :( :( please please help me i will be thankfull
I'm busy making a different project, but it requires a lot of similar components. I am looking for a LM386 op-amp but I'm finding it very hard to get, any ideas where I could get one. DO NOT SAY RADIO SHACK. I live in the UK and can't travel very far from Newcastle so where could I get one, if it is used in any household products I have aces to a whole range of them which I can strip down. Thanks

&nbsp;you are retarted
You could maybe do some salvage.
jesus read what he wrote before you comment he said HE&nbsp;DOESNT&nbsp;LIVE&nbsp;NEAR&nbsp;ONE
maybe a amplifier? strip it down and try to find one!
some stores (I don't know what equivalent of jaycar is in england, maybe they have one) will mail your components out to you so it can be just a matter of searching electronics hobby stores in the UK and checking if they mail out to you.
