I worked with someone who had previously worked on park robotics, and apparently they had to guarantee that the character could not injure a child to be able to put them in parks - a particularly high barrier to actually doing so.
Take a look at industrial cobots (not a typo). They feature rounded corners, have very little to no "finger pinchy areas" and lots of force feedback sensors.
Despite that they still require trained (adult) personal and move very slowly when actually interacting with humans.
That's the price for them being sturdy and precise.
