Dive into the world of mechanical principles demonstrated with LEGO, featuring unique mechanisms like the chain fountain, ...

[2n2r5] posted up a mechanism that we’d never seen before — a threadless ballscrew that turns rotational into linear motion with no backlash. It works by pressing the edge of three bearings ...

Linear versus rotary, electric, pneumatic or hydraulic, here’s a look at the basics of the actuator component.

RC servos are a common component in many robotics projects, but [Giovanni Leal] needed linear motion instead of the rotary actuation that servos normally offer. The 3D Printed Mini Linear ...
