Compared to the steppers we stick on our 3D printers, CNC machines and paintball turrets: - They're way faster 🏃 - Far more powerful (higher torque for longer) 💪 - More accurate (higher resolution) 🎯 - And they're closed loop (they know where they are) 🤖
The only downside is that they're expensive, like hundreds of dollars.
