Otto was inspired by another robot instructable BoB the BiPed and programmed using code from another open source biped robot called Zowi.

CC-BY-SA

Otto's differences are in the assembled size (11cm x 7cm x12cm), cleaner integration of components and expressions.

Lurking a few months now in this forum I've been learning from all of you. I started assembling and playing with some Dagu robots like the Adventure bot and mini-biped and other kits available here locally, but practically the platforms were ready and the codes were complete and had to be just applied or sometimes tweaked.

I got this book for my Kindle over amazon Insectronics: Build Your Own Walking Robot and decided for this to be my first robot project. As i have been dealing with arduino for some time now but mostly building advanced outdoor sensor networks using long range RF. The book has it all from cutting the parts to programming the PIC they used to control the robot. I made a arduino version since i have a lot of arduinos at home.

Future addons:

- Use a arduino nano with a homemade servo shield to downsize the electronics

This is REG•E and he is my first obstacle avoiding robot.

He works off two Lego motors powered by 4 AA batteries and for a brain he has an Arduino Duemilanove. He uses an ultrasonic range finder to 'see' what's in front of him. Motor control is thanks to the TIP120 transistor and this tutorial here: http://www.instructables.com/id/Use-Arduino-with-TIP120-transistor-to-control-moto/

Hi all! First robot ever, saying it's not great would be an euphemism, nevertheless I would be very glad to get some feedback from you.

How it works : two switches on the front, when it meets a wall, andrew goes backwards and turn, then turn the other direction and goes forward again (see video - about the video, sorry for the poor quality, I had to use a phone, I can post a better one next weekend)

This is the LMR robot for the today's Campus-Party Berlin. Its purpose in life is to help children if they are afraid of monsters in the night. The Monster Catcher stays under the bed and makes noises to catch the monsters...

The Monster Catcher is a collective work of Drakuni, Antonio, Isotope, TinHead, Frits, RobotFreak, Lumi and Francisco.

The Making

Here some impressions from the making.

Frits, Nils and Antonio elaborate on the ideas. It is important that it is a very easy-to-make robot that does not need rocket science software and hardware.

Work in progress. HexedBot can walk forward and backward. Still working on the driver program. Hopefully I'll get the video processing working so that he can follow an object or a bright light, for example a laser pointer. I'll use the Sharp sensor for collision avoidance. I've followed the plans pretty much literally out of the Robot Builder's Bonanza book, and added a second deck to mount the Arduino Uno board, the Pololu servo controller and batteries. The construction material is 6mm Sintra PVC plastic from Solarbotics. Still a lot of work to do, but wanted to share my progress :)
