Let's Make Robots Robots

This is propably fourth or fitfh evolution version of my first finished and working robot ever built.

It has Oopic-R controller as brains, 2 cont.rot. modified servos as drive system, 2 SRF04 sonars as obstacle detectors and 1 GP2D12 Ir-sensor to see edges of tables and such. And also lcd-display to help debugging.

It serves as generic testing platform for new hardware and new algorithm ideas. Nowdays i'm more of a arduino-fan but oopic is also nice board.

Parts.
where did you get the plastic base? i’m looking for cheap blue plastic sheet.

Hey! mine has the same
Hey! mine has the same ON/OFF button :smiley:

That is called Lexan or
That is called Lexan or polycarbonate sheet. Unlike acrylic, it is much stronger and does not crack. It is also easier to machine. It also comes in many colors.

Nice job
Can’t beat plexaglass. I do the same. I am curious. I just got an OPPIC processor and motor drive at a good piice. It is an OOpic Version 1.A7 processor board. It looks like a nice setup but know nothing about OOPIC. Is it worth learning? It is an older one I know mabe 1999 but in new condition. Any imfo concerning OOPIC from anyone would be appreciatted or it will go back to Ebay.

It looks more or less like

It looks more or less like Lexan/Polycarbonate, because of that bent piece of whatever that is that is attached to the sharp IR sensor. I suppose it could be plexiglass though. Do you have any experience with lexan though?

Where would I be able to get
a dark blue 3’ by 4’ sheet?

complex design! very well

complex design! very well organized and structured!!

looking for the video :wink:

It is acrylic, got it from

It is acrylic, got it from local hardware-store here in finland.

Bottom one is 4mm thick and top plate is 2mm.

Its called google my freind.
Its called google my freind. Thats all i did was google it. Thats all you had to do. scroll down to blue http://www.usplastic.com/catalog/product.asp?catalog_name=USPlastic&category_name=21314&product_id=9792.

Video added
Video added, yay! It’s a bit dark but hope you see something. Gonna try to get better one in daylight.

Video soon, hopefully

I’ll try to get video soon uploaded. I was just inspecting the bot and noted that one of the sonar wires ripped off :frowning: (bad soldering).

Got to fix that one first.

 

Edit: Video added!

it looks like it gets way
it looks like it gets way too close to things. You should change that value at which it decides to turn.

**OOPIC **
is a object-based programming language. its reccomended by electronics 4 dummies
