Let's Make Robots!

Maker Faire 2013 in Hannover

Last weekend the first Maker Faire has been landed in Hannover, Germany. It was a great success and a real time experience for me. The only bad things I can tell, it was too short (only one day) and too hot. Approximatly 4500 visitors have visited the exhibition and our booth was surrounded with crowds of people all the time. Too less time for me to walk around to see other makers. 

Red BoB has arrived

Hi,

I'm so excited, and FrankenBoB, too. Isotope has sent me 3D printed BoB parts and a cool name badge from Canada. Thank you so much, Vadim. This time I need to pay you the beer at Campus Party.


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.

MURCS - Sneak Preview

Hi,

this is MURCS - Multi Use Robot Construction System. My first self design chassis using laser cutted parts. Today the parts arrived and I have quickly assembled them for a foto shooting. 

The neon green chassis looks great. 

 

The design was made with SketchUp, my favorite tool for 3D design. This is a early design using a second platform.

IOIO-SHR version 2 sneak preview

Started this weekend with the 2nd version of my IOIO-SHR (Start Here Robot). Because Santa brought me a Rover 5 chassis on christmas, this would become the chassis for it. I got the 2WD version including wheel encoders and the motor controller board.

Here are some shots from the assembly test.

The IOIO is mounted on a carrier board with 3 pin headers for all IOs. Some Jumpers are available to select the supply voltage for the IO headers, 3.3V, 5V from the IOIO or external servo voltage.

FezBridge - Android Debug Mode meets Fez Domino

FezBridge is an Implementation of the Android Debug Bridge (ADB)  on a .NETMF device, the Fez Domino from GHI electronics. It is based on the MicroBridge project from Inopia alias Romfont. The ADB is available on most Android phones (Andropid v1.6 or higher). This is one of the advantages against the Android Open Accessory mode. which runs only on a few phones.

Android Open Accessory DIY DemoKit

At the Google I/O 2011 the new Android Open Accessory Development Kit (ADK) has been published. This allows to connect Accessorys to your Android phone and communicate between the Accessory and the Android via USB. The Accessory has to implement an USB Host, while the Android acts as a USB client.

Robot family picture

This is my complete robot family. 24 robots so far. Build over the last 15 years. Some of them are dead or incomplete. But most of them works.

A higher resolution image can be found in my flickr album, including tags of every single robot.

 

 

 

Dagu's Ultrasonic Sensor testing

I've made some testing with the ultrasonic sensor from Dagu. Tests were made on the platform the sensor is build for, the Asuro. The sensor works pretty well, most of the the time. The range of obstacle detection is from 0..25cm. Sometimes the sensor dismiss an obstacle, when the objects is not directly in front of the robot.

 The video gives some impressions, how this sensor works.

Starting with .NET Micro Framework

My current project is a start here robot with .NET Micro Framework using a FEZ Domino board from GHI Electronics. The FEZ Domino is pin compatible to Arduino, but has more processing power (ARM7 core with 72MHz clock), 3 UART, 2SPI USB host and micro SD-Card support.

After building some Arduino based robots I think it's time for a change. Before I start build the robot itself some testings were needed to find out if the FEZ Domino is a worthy successor for the Arduino and can I use my existing Arduino shields.
