We present the design and implementation of a vision-assisted pick and place robotic machine for laboratory activities. The robotic device can automatically locate and pick small electronic components placed in containers in scattered order and put them in their final assembly position, indicated by pre-located visual marks on a printed circuit board. The execution of these tasks is supported by the design of two main systems. The first one consists of an image processing algorithm, fastly and precisely, capable of recognizing objects of interest arranged in containers. The second system involves the design and implementation of a Cartesian robot with four degrees of freedom. The robot's electromechanical assembly design involved implementing a PID controller and a power and sense electronics module. The resulting robotic machine solved the surface-mount capacitors manipulation problem, rendering an accuracy with a maximum deviation angle of ±15°, during the components placement tasks.
