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:

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.


Note: You can follow some projects some of the time, but you cannot follow all the projects all the time.

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
