Done!
As per @Timple advise I have removed the email registration.

You don’t need to register or even visit the website.

here are the updated steps:

  • clone the debians (still need to figure out how to deploy with apt)
    git clone -b melodic git@github.com:mowito/safe_teleop.git ~/safe_teleop

  • and then run the setup file to install the debians and dependencies. You can do it manually also, all the debians are in the debians folder.
    cd ~/safe_teleop && ./setup.sh

  • run the launch file
    roslaunch ~/safe_teleop/launch/maxl_sim.launch

Enjoy! Do provide the feedback!
