Industrial robot architectures and kinematics, ROS, machine vision, collaborative robot (cobot) safety standards, Arduino & Raspberry Pi prototyping, servo/stepper motion control, and the sensors automation depends on.
Answer a few questions about payload, reach, and task, and get a recommended robot architecture — articulated, SCARA, Delta, or Cartesian — with the reasoning behind it.
Compute the required motor torque from load mass, radius, and acceleration, and get guidance on whether a stepper or servo motor fits the result.
A searchable reference of proximity, photoelectric, and force/torque sensor types, filterable by what you need to detect.
