For the moment I'm printing and testing.
for the aseptic models) saves valuable facility space and makes integration easy, yet despite their size, they have a large payload capacity. The first is to supply the servo motors with 5V from an external power supply with enough power to move the 6 servo motors simultaneously. The robot should position all of its servo motors at 90 degrees.
The actual movement is intermittent, but because the waiting time between each movement is only 10 milliseconds, the movement gives a sense of continuity at low speed. Control the robot from the control panel.
We will develop a robot arm that picks up parts with a gripper and places them elsewhere. e6)EIgf"{lf||U7$8GzR'F5'_)F]TH_rGetd|lF hV23dp",5g;p~Y7U?K To support the movements of the servo motors, we need to balance the weights of the arms a little, taking into account the weight of the arm at the other end. The instruction line indicates the number of the target label.

This example shows how to model a 6-axis industrial robot arm from scratch, using the 3D models provided by the manufacturer.
The ultracompact VSA Series 6-axis articulated robots offer the highest speed and repeatability in their class. Servo motor 1 moves at normal speed and servo motor 0, which is the gripper, closes it at slow speed because it is in a loop. Be careful, overheating 3D printed parts could deform them and make them unusable. The six servo motors are controlled by the Atmega328P microcontroller via the PCA9685 module, which has two important functions. Waits for a specific state of a Di input signal.
For the other stages, the adaptation method is similar. All servos require their own PWM signals. With the function, we tell the PCA9685 module to move motor 5 to the position resulting from subtracting the value of the rising edge (0) from the falling edge (350), and with the function. ) The LED1 light should turn on and the LED2 light should flash.
