The range of servo-type micro operating range from 120° to 360°. Actuators type micro work on the same principle as their larger counterparts - using the same attachment hardware and external software that for single beds and mega, you can manage smaller services like micro. Serwomechanizmy micro are a very good solution for people starting their adventure with systems embedded or robotics. In offer we have also a servo driver that is compatible with Arduino and Raspberry Pi.
The servo light company Okystar is a great choice for designers looking for small, efficient mechanism for their projects. The operating voltage of the device is from 3.5 V to 6 V. The rotation angle is 180°. The kit lifts and screws for Assembly.
Servo Kitronik based on the model Feetech FS90MG-CL metal gear. The power voltage from 4.8 V to 6 V, the torque is 1.8 kg / cm to 2.2 kg*cm, range of motion 180°. Wire was completed connectors krokodylkowymi.
Small servo-type micro connector Grove, which provides a direct connection to it with a cost Base Shield. The power voltage from 4.8 V to 6 V torque: 1.8 kg*cm and speed-0.10 sec/60°. The dimensions of the servo drives in size: 24 x 23mm x 11.5 mm Weight 8,5 g.
Set of 2 servos 9g allows you to increase the movement capability of the robot Allbot. The set includes two piece of servos and a set of mounting screws. Servo type micro. Speed: 0,09 SEK/60°. Torque: 0.95 kg*cm. Dimensions: 22,9 x 27,3 x 12 mm. Weight: 9 g.
The geometric dimensions, weight, range, power supply voltage and the control method are the parameters that must be considered when selecting servo type micro. In the same way as in big money, the final effect determines the torque and the rotational speed of the servo. Torque describes what weight the servo can move with the support arm of a certain length - hand that, as a rule, a pusher mounted at one end on orczyku servo, and the second object, which is controlled by servo. The rotational speed of the servo, as a rule, can be parameterised as the time required to perform pivot axis with the pivot at an angle of 60°. This is a standard adopted by all manufacturers, but before buying do not forget to check the specifications of the servo! If you are a beginner in the field of robotics, and servo need to control, for example, the height of a small airplane with remote control with a wingspan of up to 1 m, the optimal will be to use the servo speed 0.17 sec/60°. For control of ogonowym rotor helicopter with remote control, you must use a servo with a speed of 0.05 sec/60°, to instantly counteract the torque of the rotor.
Process control serwem directly from the Arduino has a simple design. It is best to connect the servo to Arduino using special pads, given the fact that the maximum current outputs GPIO in Arduino may be insufficient in relation to the hardware requirements of the servo - max working current of one output of the Arduino is 40 mA. Serwomechanizmy that current does not exceed the maximum load current outputs of the Arduino, you can connect directly. In that case, the black wire of the servo should be connected to the ground terminal (GND), red wire for output voltage (+5 V), and the yellow wire to one of the terminals that output a signal of two States. The red wire can be connected also to the output set as digital output, set to logic high, and the black wire to the output of the digital set in the low state. Using servos, whose power consumption exceeds power the Arduino, use an external battery or power supply, with the purpose of correct and safe operation of the pole the weight of the external voltage source must be connected to the ground terminal (GND) of the Arduino. Another method of managing services, to load program code in a compiler specialized Arduino library “servo library”. This library provides comprehensive management services. If you want to control more servos, it is better to take an external controller and separate power supply with an output voltage range from 4.8 V to 6.0 V.
