Rewrite of Hopper's body controller and kinematics unit in Rust
Hopper (Named after Grace Hopper) is a 3D printed hexapod robot running on ROS.
It's brain is a Raspberry Pi 3 running Ubunut Xenial with ROS Kinetic Slowly porting into pure Rust.
The platform is modeled and 3D printed by me and is still a work in progress. It's heavily inspired by PhantomX Hexapod from Trossen robotics

In case build fails with alsa-sys build stepa you want to install dev dependencies for alsa.
On debian the package is called libasound2-dev.
You may also need libssl-dev depending on which ssl library you are using.
And libudev - libudev-dev on Ubuntu
sudo apt install libssl-dev libasound2-dev libudev-dev -y
# camera
sudo apt install libv4l-dev libclang-dev -ydepending on if you are running as user or system you'll want to have the following config
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}either in ~/.asoundrc or /etc/asound.conf
