Let's Make Robots!

My first Robot! Looks familiar!

Uses Ultrasound to navigate as per the Tutorial code

My first Robot, made with the "Start Here" project :)

Rear

I added a switch in the little box between the motors which houses some of the wires.

The box

I'm not sure if adding a switch directly on the power wire is the right thing to do, but it works :)

Also i wasn't too sure about wire sizes. I have been robbing wires and connectors from old PC's and stuff around the house :) The wires on the motors are hard drive power wires. They seem a bit thick, will that make less power get to the motors?  The wire from inside CAT5 seems quite good, would that work for these sort of projects?

I tried to use plugs and connectors where I could so I could easily change things around.

An important lesson I learned was planning the layout of your parts.  I found it takes 2 seconds to stick a motor or sensor in place with doublesided foam tape...  It takes 5 minutes to get it off and remove the tape when you stick it in the wrong place! :)

Any how, My first robot and my first venture into the land of forums too, so please be kind :)

Thank you to Frits for the tutorial and everyone who commented there Great job !

hay guys , i m a  beginner robot builder. Can u please post the source code. i would highly appreciate it

thanks in advance ! :)

 

Could you email me the source code you refer to in your description, I want to implement it into my circuit, I want to get some type of guideline with the code for the ultrasonic sensor.

Please join LMR because you want to share and take part.. or get lost.

You are extremely close to a flame & getting kicked out for spamming and bad karma.

You are VERy welcome to join LMR if you are joining. NOT if you are just asking to get stuff out and move on. Post something, be a real member, or get lost!
Good job! I really like the way you've arranged the components!
  Thanks for the comments and the tips :) I already snapped a few single core wires at the joints and i hadnt though of the problems that would cause if the break were hidden in the insulation.  I did start to modify the code from the tutorial, but I am struggling a bit. So I think I will go back to the very basics and start from the ground up using the tutorial as reference. Once I have it wandering again I will post Video :)

Well done! As Frits said, programming it will be fun. This is where you can give it some personality and make it stand out from the crowd. Perhaps make it throw a tantrum when it gets stuck in a corner.

I usually set mine up so if there are no obstacles after a certain period of time then they look around and change direction out of bordom. Perhaps go towards the nearest obstacle out of curiosity.

You nailed it, yo.

Very nice job!!

- And now for the fun part, programmig it :D (And video!)

Snagging wiring from old PCs is great. The 3-wire cdrom->mobo audio cables can make really groovy sensor wires (pay attention tho, they may have 4 connectors but only 3 seperate connections (common ground)).

The wires you used for the motors should be just fine. You'll likely come into problems using wire that is too small, but going too big isn't that large of a deal (as long as you don't go ridiculously big). CAT5 wire is probably too small for wiring those motors. It should do okay for simple signal lines (like button input), or for tiny motors (like pager motors).

Solid copper wires are not as useful as braided ones. When a solid wire bends/folds a couple of times, it will snap. Within the isolation. Nightmare debugging!

Good start. Both the bot and the post.
