This circuit is not the very latest in robotics, but it may be of interest to those of you involved in making little robots using popular and inexpensive components. The proposed idea is a ...

One of the worst things about sewing is finding out that your bobbin — that’s the smaller spool that works together with the needle and the larger spool to make a complete stitch — ran out of thread ...

It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

Figure 2: By using smaller servo drives, robots have less dead weight to deal with, reducing their wear-and-tear. The ongoing trend of micro-sized servo drive technology is driven by Moore’s Law and ...
