urdf-rs 0.1.3

# urdf-rs
[![Build Status](https://travis-ci.org/OTL/urdf-rs.svg?branch=master)](https://travis-ci.org/OTL/urdf-rs)

[URDF](http://wiki.ros.org/urdf) parser using [serde-xml-rs](https://github.com/RReverser/serde-xml-rs) for rust.

Only [link](http://wiki.ros.org/urdf/XML/link) and [joint](http://wiki.ros.org/urdf/XML/joint) are supported.

[Documentation](https://docs.rs/urdf-rs/)

## Example

You can access urdf elements like below example.

```rust
extern crate urdf_rs;
let urdf_robo = urdf_rs::read_file("sample.urdf").unwrap();
let links = urdf_robo.links;
println!("{:?}", links[0].visual.origin.xyz);
let joints = urdf_robo.joints;
println!("{:?}", joints[0].origin.xyz);
```

## Limitation

### order of elements

You have to repeat "link" tags and "joint" tags in the urdf, like

```
<link />
<link />
<link />
<joint />
<joint />
<joint />
```

Below style does not work now.

```
<link />
<joint />
<link />
<joint />
<link />
<joint />
```

### Mesh

* Only .obj files are supported now. Please convert meshes and edit the urdf.
* `package://` path is ignored. $CWD is used instead.
