[Misc] Selling our robot vehicle prototype

For the last two years, my friend and I tried to build a prototype for an autonomous delivery vehicle. He’s called Ben. Unfortunately, after thousands of hours of work and even more dollars spent, we are forced to discontinue our project due to lack of time, skills and energy. So if you guys want to continue the work or use it as a base for your own project, we would happily sell it to anyone who’s interested. As a side note before we get into details: we would have never made it this far without you / this community. Thank you from the bottom of my heart for all your help and your interesting and helpful posts. Although I feel extremly sad that we will discontinue this project, I hope that some of you can and will finalize it or utilize it for something else.

Here are some images of the robot: https://imgur.com/a/ILPOa84
