So let's start discussing the project. The following are the software and hardware prerequisites of this project:
| No | Component/software | Link |
| 1 | Low-cost VR headset | https://vr.google.com/cardboard/get-cardboard/ |
| 2 | Leap Motion controller | https://www.leapmotion.com/ |
| 3 | Wi-Fi router | Any router can connect to a PC or Android phone |
| 4 | Ubuntu 14.04.5 LTS | http://releases.ubuntu.com/14.04/ |
| 5 | ROS Indigo | http://wiki.ros.org/indigo/Installation/Ubuntu |
| 6 | Leap Motion SDK | https://www.leapmotion.com/setup/linux |
This project has been tested on ROS Indigo, and the code is compatible with ROS Kinetic too, but the Leap Motion SDK is still in development for Ubuntu 16.04 LTS. So here the code is tested using Ubuntu 14.04.5 and ROS Indigo. If you are ready with the components, let's look at the design of the project and how it works.
