- Robotbeat 6y agoQuasi-direct-drive actuators (BLDC motors with position Feedback and a modest, 5:1 or 10:1 gear ratio) are what you’re thinking of for Spot and similar. For Atlas, you kind of need the specific force and low speed specific power than hydraulics give you. That’s what Boston Dynamics uses for those larger dynamic robots (Atlas, Big Dog, etc). (Hydraulics are under-rated! They can be electrically pumped, so they need not be super loud.)
