Closed loop stepper vs open loop stepper

Petar Crnjak

Stepper motors are widely used in open-loop systems for their simplicity and cost-effectiveness, but they suffer from missed steps, resonance, and energy inefficiency. This blog explores how closed-loop control—especially using...

Types of joints in robotics

Petar Crnjak

Robot joints are the movable connections between different parts of a robot’s body, analogous to the joints in the human skeleton. These links allow robots to bend, twist, rotate, and...

Measure current of DC motor

Petar Crnjak

By measuring motor current, you can monitor and control torque, manage load changes, and protect the motor from potential overload conditions. Effective current measurement also helps to maintain energy efficiency...
