Help with Picaxe and serial LCD

Chris the Carpenter's picture

Ok Picaxe Basic Gurus... I think I need some code snippits...

My new serial enabled LCD just arrived and I can't seem to get it up and running. I am using what I think is the standard picaxe basic commands but I am only getting white blocks, x's and some other random symbols. To be honest, I am confused with a lot of the serial commands in general, the whole ASCII thing and anything written as 0x7C or 0x14 or whatever.

Here is the display.

Campus Party - Berlin 2012

TinHead's picture

Hi LMR,

As you might seen on the first page a new CP is going to happen in Berlin on 21-26 August in an airport :D 

I'd like to go, last time I got invited but even without an invitation the trip would be somewhere around 400 Euros including the airplane ticket, and if it will be like the last time it will be worth going. 

Frits can you post some more info on this when you get some time/more inside info?

Cheers!

Swarm Robots - Brainstorming (Football robots)

lumi's picture

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:

Robot sweep taking too long

A few friends and I have been attempting to build an autonomous robot for our project using:

Arduino - Duemilenove 

Adafruit - Motorshield

Sparkfun - Bluesmirf

Parallax - Ping sensor

We were able to configure the robot such that it is able to run autonomously. We also tried implementing some code in processing to show where an object is detected and how far it is from the ping sensor; it looks similar to a radar.

i made this for fun.it was designed for 6axis & gravity detection. the mercury switch is not perfect,i have to do some anti jitter work. Read more

Rubik's cube solving robot

MarkusB's picture

This blog is dedicated to build a Rubik's cube solving robot. I'll not give you any guarantee to even update this blog or finish it. I just want to share and discuss some ideas.

The first thing I did was to buy 3 Rubik's cubes at taobao.com (a kind of Chinese Ebay), each around 10 RMB.  I bought 3 pieces, because I wanted to avoid one or two samples are getting damaged during my experiments and evaluations and I needed then to find exactly the same kind of probes for my experiments again, which can be quite annoying.

Ant Bots and Spyder Bots--My Version of Swarm Robots on LMR

vishurockssrivastava's picture

Just browsing through LMR, I found that many people are interested in the concept of making swarm bots (the most prominent being Lumi and his team, Aaronsuper1 and warnew). After a short discussion with each of the 3 I mention via shoutbox, I decided that swarm bot is going to be my second project.

This is the first prototype for a robot that can turn into a circle and roll itself around or crawl for locomotion.
Skitters around, loves and/or hates its own kind, communicates via light.

Hakko (compatible-affordable) Digital controlled soldering station

Due to recent  intense smd soldring work, my 25watt antex soldering iron was begining to show its limitations......

... so out with the old and in with a new Hakko 907 (compatible) soldering system.

Truth is i found the temperature controller first .... which was a godsend because the current stye of hakko enclosure did not "Grab" me.....

...... Creating my Custom Box is too awsome to even think about :-)

Arduino questions

Hello,

i'm from germany and i'm trying to build my first Robot with the arduino Platform.

I've desided to build my own shild for the arduino.

It should be able to drive two motors and to connect 4 -5 servos to the arduino.

The first problems with the L293D Motordriver are solved and I've done that it works and avoids objects.

Today my servos arrived and i tested my shield with the servos.

and then the first problem:

Work HERE on giving some of our robots emotions....

I am not sure why I decided to start this topic on thia area of the forum (other than the fact I REALLY enjoy my FEZZ Mini Robot!!!).

Do you want a robot that runs around the floor and its only job is to not collide with things (some robots do more)??? I want MORE than that! A rather simple simulation of emotion would be really cool and freak out your friends and neighbors!!! Its time for some AI !!!

Others, please join us and help this website do almost as much as some small AI laboratories have done.

Design of 3D printed enclosure

AndreyNech's picture

We are currently working on the new version of our BeagleBoard-xM based robot. The main reason for redesign was the lack of wheel encoders which prevent us from developing more sophisticated navigation algorithms. That is why we decide to use Dagu Rover tracked chassis. However, not all our electronic could be fit in to the chassis, hence the need for additional enclosure on top of it.

Robot Teaches Itself How To Walk.

FR's picture

Very interesting work of making a robot learn about itself using gyro feedback and programming in rules based around this.

Looks like it would be a quicker way to program robots to do complex tasks perhaps...
