Six revolute joints, one prismatic joint, one degree of freedom.

This Siemens NX Animation Designer study shows the kinematic sequence of a UAV landing gear retracting through 90° in 1 s (average angular velocity π/2 rad/s) and returning to 0°.

[Nima Shahnazipour @NIXODESIGN]

Scope: this is a purely kinematic study (rigid bodies, ideal joints, prescribed stroke). Hydraulic pressure, actuator sizing, locking forces, and inertia need dynamic analysis, which is the next step.

[Nima Shahnazipour @NIXODESIGN]

With 6 revolute joints plus the actuator, the mechanism has one degree of freedom, so one input drives every link through the loop-closure constraints. Because the linkage transmission is nonlinear, the leg’s instantaneous angular velocity varies along the stroke.

[Nima Shahnazipour @NIXODESIGN]

The input is a single hydraulic actuator, modeled as a prismatic joint with a prescribed stroke. Extending the rod rotates the leg up to the stowed position, and retracting it deploys the leg.

[Nima Shahnazipour @NIXODESIGN]

From individual links to synchronized deployment, every movement is governed by the underlying kinematics.

The objective is not simply to animate the mechanism, but to make its kinematic behavior visible and demonstrate how each component moves as part of an integrated mechanical system.

[Nima Shahnazipour @NIXODESIGN]

The study captures the motion of the interconnected linkages, revolute joints, kinematic constraints, and prescribed motion inputs governing synchronized gear deployment and retraction.

A few projects I worked on last week. The team had an incredible season, with 6 wins in 7 rounds and another championship title secured.

Big thanks to Trystan Hart and FMF KTM Factory Racing for the continued collaboration. It’s been great being part of the racing season.

Skyways provides long-range, heavy-payload, autonomous drone solutions for the harshest environments. Unlike traditional logistics methods that are slow, inflexible and costly, Skyways solutions are fast, flexible and cost-effective.

Skyways Ferox unlock missions that helicopters can’t serve efficiently and typical, electric-only drones can’t reach. Skyways Ferox do this by employing a Dual-Hybrid Design™ that takes off like a helicopter and cruises like an airplane

Happy to share my SubD modeling workflow of a 1997 Porsche 911 (993). I show the complete process, from modeling to UV unwrapping.
Hope you enjoy watching it.

Porsche Carrera 4S in Miami Blue. Available on my website! I created a custom 3D viewer so you can view it in 3D as well.

📌Bad topology is a silent project killer.
Engineering a digital twin requires more than just a good-looking render.

I’ve even built a custom interactive 3D viewer on my website so you can inspect the model yourself
