Object fall off screen when programming

[MMichelle]

Hello! I’m a teacher attempting to learn Robot Mesh Studio so I can use it with my students and I’m stuck. I built an object and programmed it, but when I press play, the entire build just falls off the screen. I’m not sure where I went wrong or why it is happening.

I wanted to build just a simple mechanism where the motor would turn one gear.

Any thoughts on what I might need to change/fix?

Hi MMichelle.

Gravity, alas. You must place a surface under your assembly for it to sit on.

The Base Plate, Full Field and Floor from the Misc category of the parts library are not subject to gravity.

Cheers, Sam.

That worked! Thank you so much for your help.
