Let's Make Robots!

Here's my version of the Start Here Robot.  It pretty much follows Fritz's directions, with some minor adaptations of the body based on the material I had on hand, … Read more

Steam Punk Robots

I was visiting my sister this past weekend. I showed her son Alec some of the great bots here on LMR. Alec has a couple of interesting model engines, and has been trying to generate electricity with them. His dad actually does this on a bigger scale with diesel engine running biodiesel and a generator.

Anyway, one of Alec's engine models is a Stirling engine. He has this model.

This is a concept for a drink server robot, Mr Boston. My initial concept is to build him out of an ice cooler, adding wheels, sensors, actuators, etc.

Some initial thoughts:

Yin and Yang

This is an idea for a pair of matched robots, "Yin" and "Yang".  This pair will be almost identical in phyical construction, but very different in programming.

Yang will be aggressive, and constantly seek to attack Yin.  Yin will be passive, but not defenseless, preferring to dodge and avoid rather than directly confront.

Slip Ring

To support my idea for building a 360 degree range finder, I want to build my own slip ring assembly.

I'm thinking of using a copper clad board to create concentric rings. I found a manufacturer that uses this technique. I posted a picture from them below.

Introduction

This is a concept for a robot to monitor and manage my swimming pool.

Design Goals

360 Range Finder

I just received my SRF05 and I can't wait to start using it.  While I was thinking about it, it occurred to me that I always see the SRF05 mounted on a servo, which allows maybe a 180 degree field of view for a robot. I wondered if anyone ever mounted a range finding sensor on a motor so a robot could see in every direction. 

I think I may try to build a 360 degree range finder, but I wanted to open this as a topic and get some ideas. Here's what I'm planning. Let me know what you think.

Hardware

While building my own 'Start Here' robot, I made a goof. I soldered on about 12 inches of 18 ga stranded wire to the motor contacts. Even though I reinforced it … Read more

My Robot Habit

My robot calls to me. 

It says, "You don't need sleep.  You need to rebuild my chassis.  It's too hard to replace the batteries, and I'm down to 4 volts here."
