Maxhirez' PICAXE board

9-29-2014: This update just adds the zip file containing the board in its current layout. Send the zip file to your favorite board house and get your own stack of boards. :) I still have a few that I am dispersing.

A week or so ago Max was trying to find a layout for a PICAXE 18 or 20 board with an L293/754410 motor driver. He was hoping for something similar to what sanc04 assembled.

Wheels - The Making of Blaster Shark (Sumo)

After the design of the body and motor mounts I can get an idea of what kind of wheels I need.  The things that are important to consider is the width and diameter.  Both are restricted by the dimensions of the the minisumo.  In my case, since the motor shaft is offset, I can go with a smaller diameter wheel and not worry about the bottom clearance of the robot.  But since the motors are somewhat long, I can't go with a really wide wheel.  With this in mind I figured that a wheel diameter of 40mm and a width of roughly 20mm would suffice.

Workshop basics - the mechanical side of robots - post 1

Given the fact that I'm stuck in the middle of 3 months of 75 hour weeks, and Mrs Steve is *still* grumpy becuase there are no tiles on the kitchen wall, it looks like I'm not actually going to be able to build robots for a while, so I thought I would write about some area's instead.

I have found LMR's blog roll one of the most useful places to learn about robots and robot building, and so I thought I would add something myself.

 

WhiteBOB - preview

This is WhiteBOB, my member of the BOB family. Because I have no access to a 3D-printer this robot is build from polystyrene sheets (3 and 1mm) and a piece of PVC corner strip.

3D Laser scanner for 25USD

Believe it or not, but in China the people really can do things with less money then elsewhere in the world. Cheap 3D Laser Scanner for roughly 25 bucks. See that amazing results...

Mini Robotic Ant Farm

I have started the build of the first Drone prototype for my little ant farm project. I plan on building around 4 Drones and a Builder.

 


1. The Drones:

Chassis:

The Drones will be as simple as possible, using TH components, as is hard to prototype with SMD. A double sided, plated holes prototyping board will be used as the chassis. The board is 38mm x 38mm and it can get smaller only if I use a smaller battery.

My artificial neuron approach

February 12, 2015

A single artificial neuron can represent some simple Boolean functions like OR, AND or NAND and some like XOR not, because a single artificial neuron can only learn linearly separable mappings.

Example. Perceptron for the AND function:

Cheap & Easy Speech For Robots

I am always on the search for cheap hackable devices for robots. I have found a couple here you can use to add cheap, easy, and unlimited speech to your robot.

Rhex

I definitely want to build a 6 legged Rhex robot. Below are some drafts I made today with Sketchup. 6 standard servos HS-325, a LiPo battery, two Sharp IR distance sensors and a tilt switch.

Computer On Wheels Controller

Hi guys,
 
 
 
Since last week, I've been learning c++ and openFrameworks and creating a application to control any robot with a computer on it or, at least connected to one by someway.
 
It is supposed to be simple to implement and use.
You just need to run the application and program your robot to read the following chars and act corresponding to them:
  • 'w' to move forward;
  • 's' to mo

Drawing, Steppers, LMR Challenge and it works!

Well how 'bout that, it sorta works. I don't know if I am going to kit this one or just have fun with it, but either way, here it is.

I still need to finish the lift mechanism for the pen, but other than that, 100% solid. Woo Hoo!

 

First foray into homemade PCBs

**Update at the bottom.

  Alright guys/gals, it has been a coons age since I posted anything even remotely useful of my own. I have managed to break that trend with this 'bitty blog, somewhat. I say somewhat, because, everyone and their brother has posted a how to about DIY PCBs. I will attempt to offer some bit of information that others have not, doubtful. :)

I just received my OSLRF laser Range Finder!

So I received this awesome package in the mail yesterday from LightWare Optoelectronics in South Africa.

The most useless machine ever

This is a "most useless machine" i made. I used a instructable but it was a comment by "compukidmike" that was the schematic i used. 

here is compukidmike's schematic picture thing  http://www.instructables.com/files/deriv/FCQ/XPAC/G43EFYKB/FCQXPACG43EFYKB.SMALL.jpg
