Sweep Dynamics

26:1 Micro Harmonic Drive & 20:1 Micro Cycloidal Drive in action! ⚙️ Both delivering exception torque and precision in a tiny 42x42mm package. Compatible with Nema 17 stepper motors. #3DPrinting #Robotics #engineeringdesign

First three joints of Armold MK8 prototype in action. Powered by our 26:1 high-torque cycloidal drives, offering high performance at an affordable cost. #Robotics #Engineering #Automation

Side-by-side of our Armold actuators. MK8 upgrades to 26:1 reduction (vs MK7's 20:1) with a more robust design. Result: Smoother movements, heavier loads, better performance.

Our Micro 20:1 Cycloidal, and 26:1 Harmonic drives. Both 3D printed and made from readily-available materials. Perfect for desktop automation tasks and hobbyists!

Our new 26:1 High-Torque cycloidal drive! ⚙️🤖 Exceptional torque with minimal backlash, perfect for precise movement under load. We've engineered this drive to withstand repeated use while maintaining affordability. #Robotics #3dprint #mechatronics #Gearbox

Our fold-ball sized 26:1 harmonic drive! High torque and precision in just 42mm. Ideal for desktop automation and hobbyist projects. #3dprinting #3dprint #gearbox #Robotics

26:1 Cycloidal from @SweepDynamics up and running today ✅ must get printed in nylon next, then build 5 more for a 6 DOF arm

@Conor96walsh This looks fantastic! Can't wait to see the arm in action!

Just tested our mini 3-axis arm with micro-harmonic drives achieving 26:1 reduction in a golf-ball-sized footprint. The future of automation fits on your desk - perfect for PCB assembly, pick-and-place, and micro-manufacturing. 🛠️ #harmonicdrive #roboticarm #diyrobot

Testing our 20:1 Micro Drive under load conditions! 💪🔬 Our compact cycloidal drive powers through this stress test—supporting joint 2 of our 6-DOF Armold with another stepper motor mounted at the end acting as dead weight. #robotics #cycloidaldrive #roboticarm

@Sentdex Next we need a photo of the actuators!

Idk who needs to see this, but the Unitree G1 with the back plate off:

@viktor_vrp Is it back-driveable?

First attempt at a custom servo with harmonic reducer using off-the-shelf parts. It works, but I’m not thrilled with the results: – Couldn’t tune the controller properly due to firmware limitations – Gearbox design flaw: the output plate shifts under load (friction fit, no pins) – Awkwardly bulky — the gearbox was originally made for a stepper motor

@inventorOli This looks great. The movement is so smooth

Working on a cheap, powerful and robust robotic arm. Still need to add a gripper, replace plastic parts with aluminum and fix dangling wires.

Demonstration of our 20:1 drive in our robotic arm prototype. Right torque & compact form factor. #robotics #cycloidaldrive #3dprinting

The true speed of our 20:1 cycloidal drive. Even paired with a tiny 23mm Nema 17, this actuator packs a punch 🤛 #Robotics #3DPrinting #engineering

Our compact & speedy 20:1 cycloidal drive. Perfect for robotics, automation & more. #robotics #3dprinting #gearbox #diyrobot #steppermotor #actuator

@CyberRobooo So smooth

LIMX’s humanoid robot CL-3. New human-like expressions.

@phethers These look fantastic!

It's magical
