Thank you for explaining this issue. So commercially available robot needs Jetson TX2 (or Wandboard) with ROS and some hardware from safety tools vendor like Pilz or Sick. And the whole safety assessment from TÜV with official certificate. That was helpful!

Depends on what your market is. The suitability of Jetson TX2 for industrial robots is quite debatable, for instance. Might be sufficient for service robots, but really depends on the notified body accepting your argument. Also don't forget that the actuators (brakes? power?) are part of the safety architecture as well. Word of advice: You need to have a 100% waterproof concept, otherwise your product will _not_ make it to market. Don't try to guess your way around the safety system, it will cost you dear later on.

What market are you looking at? Its all about risk... if you're targeting the medical domain for example, you have a multi-year project just to get thru the certifications. Conversely if you're just looking at creating a toy with limited movement, weight and power then the risk is significantly less. Get an engineering safety consultant to have a look.

  Industrial cleaning, machine is slow, but has many liters clean and dirty water inside. Just prototyping it and thinking how to achieve reasonable price. 30-50k is too expensive, janitor is cheaper.

    Robotic lawnmowers may be a good application to draw inspiration from. They need to be low cost and likely have similar safety requirements to meet in terms of avoiding collisions and going out of bounds.

    If you want a solution, don't develop your own. Industrial robots can be purchased on Ebay for <10k that have already had the certification and engineering done. Then you just need to do the easier job of engineering your specific task, versus an entire robot + your task.
