💡 What is a hollow-shaft gear reducer used for in small robotic arms?

It's handy for compact robotics where space is tight and direct motor coupling matters. - For precise motion control, reducing speed while increasing torque - Handy for tight mechanical envelopes in robot grippers and arms - Easy to integrate with standard NEMA 11 BLDC motors and slim housings - Improves repeatability and reduces backlash in linear motion systems
