Unity robot enviroment (EN/HU)

I want to have a robot simulating enviroment in unity with loading robots, armature and other objects such as tables packs etc. I already have a robot (6 axis system) in peaces . Basically i seek help for someone who can make a working enviroment with robot movement simulation. Possibility to undo moves and actions. Place coordinate systems to move the robot from there or from a control panel where you can navigate it. I want this app to be build in front of me and with me because i want to learn how to build it too and so i can modify it in the future. I need implemented coordinate systems in every unit so i can move them in space. The requested models i will have and i will send to you if needed. Also implement a system where i can select points in 3d and the robot somehow pass through them (or a line). PS: if we finish quick i will give a bonus at the end ($)
