Workshop basics - working with templates

Just a quick entry to cover a point asked by Antonio about using templates.

I'll use an example of some leg components from a hexapod that I am working on currently. Here is how I made them to be accurate to each other, and also accurate to the design. I'll add pictures to this post when I get home.

The component is a joint between two servos, and is a complex shape - A circular section at the end of each joint with a curved centre brace between the two.

I will post a picture of it at some point, but it's essentially the middle leg joint of a bot like this:

This is my latest creation. It is a Hybred Boe Bot built up from a chasses. It has 2 power supplys, one for motors and one for electronics so far. I plan on adding … Read more

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.

miniq or start here?

hello everyone ive recently made some robots that i couldnt quite complete because of lack of experience so ive decided to take some good advice and look for a nice easy robot kit to teach me programming and other robotic skills and so i am stuck on 2 kits. i cant decide which to use.

Real-time enough? About PWMs and shaky servos

We are currently working on the next incarnation of our software and hardware platform for vehicles controlled over the Internet. Among others, we decide to investigate the way to control our robot without micro-controllers. In fact, BeagleBoard has a lot of GPIOs available. In addition, three hardware PWM generators and I2C bus should be enough at least to control the tank with camera, compass, GPS, and sonar.

Finds things to play a beat on.

WiiCamera Break Out Fail (Not my fault)

It seems that God is not without a sense of humor...

So, I had a bit of a run there for a while of producing boards which later became coasters. Bound and determined to not let that happen again, I set out to design my WiiCamera break out boards. I carefully layed out the circuit, breadboarded each and every part, and then designed a neat, simple PCB around the breadboard circuit.

Okay this is just a concept at this point, but If it generates enough interest i'll begin finishing the design. I want to take the Sanguino, Arduinos Middle child … Read more

Alliance of Droids - Companion Robot - Help needed!

Hello everyone. Just so everyone knows, I am an absolute beginner when it comes to electronics and that sort of stuff. I built my own R2-D2, but it wasn't motorized.

I want to build a companion robot for the Alliance of Droids - my charity. I was planning to use some Arduino's for the project, as well as a controller system.

I want to know the estimated cost, the parts I would need, and some more information.

If anyone would be interested in helping me, please visit my website @ www.allianceofdroids.com.

Thansk for your help.
