Robot Size and Methods of Obstacle Avoidance

I realize that most LMRians are going to have more experience with smaller robots and that I am in the minority here, but for the few that have similar or greater experience with big boys (or relevant experiences and insights from or in related fields) I wondered if I could see if you've noticed the same trends as I have in terms of larger (greater than 25cm in any dimension) Robs and effectiveness of various kinds of near-surface detection.

       Hello LMR, this is Penny the 3 servo hexapod. Penny is not just a very cheap way to build a hexapod but a very cheap way to build a robot, period. I … Read more

arduino infrared help

Anyone out there successfully used the IR libraries with arduino? Calculon is trying to use it with some bots, but not in the way the libraries are written. Calculon is trying to get one duino to talk to another using a byte, the way that a Picaxe can.

All the code and tutorials he has googled seem to be for emulating or talking to a remote control and figuring out the protocol of that remote.

PICAXE INFRA-RED REMOTE CONTROL

So i did everything as on this guide

http://www.picaxe.com/docs/axe040.pdf

But it's not working, I think the code is wrong? Can you help me ^^

I use picaxe 28x1

Thank you <3

Juice Box Robot Plan, Needs review

***UPDATE MARCH 11: After reading the comments here I have made a couple of changes to my plans. I have replaced the PICAXE 18 with the PICAXE 28 and appropriate board. I have switched to 3 AAA cells as a power source and I have changed to servos to power the "arms". When I wrote the original post used the word "arms" as a placeholder, but while I always intended to have actuation it was never actually going to be a set of arms.

Connecting TSOP38238 IR Receiver to AXE020 + 28x1

Hello LMRians,

I am using a Picaxe 28x1, and AXE020 project board and a TSOP38238 IR Receiver

Now has video of the robot playing a game and I've attached the code used in the video. You can run this on an Arduino even if you don't have the robot as the game … Read more

IR sensors

So, I bought from an online shop an IR LED and an IR receiver, like this:

and I want to connect it to a Picaxe chip, but I don't know how. I found plenty of tutorials about this one

like this:

but no information about mine.

Could anyone help, please?

Line robot sensor

Hey guys, i want to build a line following robot and I was scouring ebay for some sensors

 

I found these but I wasn't sure if they would work, as I haven't done this before. They're pretty cheap.

Swarm Robots - Brainstorming (Football robots)

This will be a note for my just started team project "Swarm Robots".

This project will take place in our hackerspace Shanghai "Xinchejian". it will be a team project where every member can join and contribute his/her skills, ideas etc.

In this blog I will ask questions and write down solutions, ideas, goals and everything else what is related to that project.

So far that's the initial idea:

Navigates via IR. Hopefully it will do that and much much more in the near future!

IR sensor-Again

I have again problems with my IR-sensors. 

I have two of these http://www.dfrobot.com/index.php?route=product/product&path=36_55&product_id=114 connected to input pin 6 and 7 on my 28x1 picaxe projectboard. And even when there's no program on the microcontroller the sensors think that there's something infront of them, but there isn't.
