When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

A hardware developer known online as 3DprintedLife has unveiled an open-source swarm robotics project that transforms each individual chess piece into an autonomous micro-robot capable of independent ...

On a chessboard, a pawn moves forward on its own. A knight jumps in an L-shape. A rook slides in a straight line. All 32 pieces are independent robots. Moreover, it is open-source and anyone can build ...

The RootBoard is a handheld computer kit with a 3.5 inch color display, a 70-key thumb keyboard complete with function keys, and a built-in speaker plus what looks like a decent s ...

This is fine.

Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...

The sensor payload (thermopile + VL53L8CX ToF) is carried by a rigid pan-tilt assembly driven by two NEMA 17 stepper motors ...
