Why would anyone build with this?

REASON 1

Design and test a robot's mechanical structure and sensors in a virtual 3D world before building hardware.

REASON 2

Write and run control code for a simulated robot to validate behavior before deploying to real hardware.

REASON 3

Prototype an autonomous vehicle or drone design and test it virtually first.

REASON 4

Learn robotics fundamentals as a student without needing expensive physical equipment.
