Very low-cost Robotic tool -The Servo Tester.

It is a very low-cost device at less than Rs 200/- absolutely required for testing small servo motors. It is. a must device for hobby robotics. It is basically to both test and ensures the center position ( at 90 degrees) of a (non-continuous spinning only ) small Servo Motor which is very important for robotic applications as, the unit that is procured from the market, its shaft may not be in the center position. Thus if used without fixing its shaft position in the center, for any robotic application, say a humanoid biped, hexapod, pick and place, gripper, claw, etc during assembling,  then it gives erratic operation at the time of switch on even if the programming is correct. 90-degree position of the shaft is the center position where from the non-continuous servo shaft moves exactly – 90 degrees…

Programless Robotics using stepper motor driver

Descriptions A very low-cost stepper motor driver that has 4 modes of operation. Can be used for excellent robotics application without using any program. 1.Working Mode: Normal Mode 1: S1 start stop button, S2 forward and reverse button, W2 potentiometer speed control. If limit reversal is required, two limit switches can be connected to the P3 pin, and the motor motion shaft is mounted with contacts, so that the motor will reciprocate within the stroke between the two limit switches. 2. Normal Mode 2: S1 forwards the start button, S2 reverses the start button, press any button to stop. W2 potentiometer speed regulation. If the limit stop is required, two limit switches can be connected to the P3 pin, so that the motor will stop moving when it touches the limit switch, and the motor will reverse after the opposite…
