Fablab version of simpleWalker

At the protospace fablab I made a laser-cut wood version of the simpleWalker. It took only 5 minutes on the laser cutter, instead of an hour behind the bandsaw! I used 4mm birch plywood. The robot works well (and smells like a campfire … oh well…) Again, it can be seen walking on YouTube (butRead more

Arduino brain for simple walker

In the first version of the simple walker I used a custom atmega32 based board. I replaced it by a ‘custom’ version of the Arduino which I dubbed ‘ottantotto’ The microcontrollerboard is a breadboard version of the ‘ottantotto’ controller. It uses an ATmega88 instead of mega168 (mostly because they are cheaper, they sell forRead more

FlatpackWalker

post image

This is a try-out of a FabLab-ready kit design for a 2-Servo walking robot. The design is inspired by the lynxmotion kits and the designs by david buckley. The goal for this project is to make all mechanical parts for the servo walker out of 1 A4 size sheet of plywood (or perspex, lexan, delrin,Read more

Simple Walker – finished

The simple 2-servo walker (which I hope to use as a fablab-ready robot kit) went through its first paces today. The microcontrollerboard used is an ATmega32.. my ‘ottantotto’s haven’t arrived yet 🙁 The robot walks well, now it’s time to make it turn, avoid obstacles, sit up, make noise, etc… You can see it walkRead more

LED matrix on arduino

The previously discussed LED matrices have been mounted on a perspex stand, and instead of the mublock controller I have used a normal Arduino Diecimila. Since the software was originally written for WinAVR using some of the AVRlib functions, I haven’t made a full functioning Arduino sketch yet. Bitmap images give the start configuration forRead more

Game of life on dot-matrix

First of all I wish you an inspiring and creative 2009! The remainder of this post is about the Dot matrix LED display. This ‘game of life’ simulation is running in Processing, communicating via serial port to an ATmega32 controller which controls two LED dot matrixes. The displays were on sale at baco-army-goods, and hadRead more

TinyWalker

Today this tiny crawler took his first steps! This robot uses 5 small-size RC servo’s and is controlled by a small custom microcontrollerboard using an Atmel ATmega8. This controller board is very minimalistic. No power supply regulator, no crystal, just the controller, some capacitors and pcb edge connectors for directly connecting the servo flat cables.Read more

TinyWalker mechanics

More details on the mechanics. The frame has been made from the cover of a discarded CD-ROM drive. The frame had been cut using metal scissors. Bras tubes have been soldered to the frame in order to form the middle joint. The whiskers are made from guitar string, mounted to paper-detect switches that had aRead more

Tchibo Cleaner Robot Mod-chip

Today I managed to kill (what could definitely be.. sure…) the last bugs in the design of the Tchibo Cleaner Robot mod-chip. In fact, it is not only a chip.. it is a tiny PCB that slots in the place of the original ATmega8 controller. On this PCB an ATmega32, 16MHz crystal and Max3232 areRead more
