![]() ![]() These servos are manufactured for Vorpal Robotics, LLC by the actual Tower Pro corporation, and they use the same high quality gears and other components of the MG90 line of servos from Tower Pro. Technical specs (from the Tower Pro official spec sheet): However you will generally not hear clicks, pops and loud buzzing noises. ![]() When running under load, you will typically hear a high pitched squeal as the digital servo circuitry compensates for loads on the shaft.Tower Pro gears rarely bind up and generally turn smoothly without any clicking or grinding noises. High quality gears made from aircraft grade aluminum.This is an extremely tight deadband and can cause issues, more discussion is below. A deadband of 1 microsecond means the servo essentially will try to adjust the position if it is off by more than about 0.045 degrees. This is somewhat technical, but the "deadband" is the amount of error the shaft position can have from the commanded position without the servo trying to adjust power to compensate. However, digital servos can also be somewhat more subject to noise on the power rails, see discussion below. Digital servos can also generally take faster PWM signals, meaning it can receive updates from the microprocessor more quickly. It is a digital servo, meaning it has more sophisticated internal circuitry that generally provides more torque, more holding power, and faster updates in response to external forces.The Tower Pro MG90S has these characteristics: A name that is purposely trying to fool the customer into thinking the servo is made by Tower Pro is also considered a counterfeit in this article. In some cases names very close to "Tower Pro" are used, such as "Tower Prop" or "Turbo Pro". In most countries this violates various intellectual property laws and is illegal. Counterfeit MG90S: A servo that is marked "Tower Pro MG90S" but was not actually manufactured by Tower Pro.In other words, the manufacturer is not pretending the servo was made by Tower Pro. Clone MG90S: A servo marked MG90S and generally compatible (same size, etc) with applications that use the genuine Tower Pro MG90s, however its label does not claim it was made by Tower Pro.They have some modifications that make them work better for small robotics projects such as Vorpal The Hexapod. They are manufactured for us by Tower Pro and so they are genuine and are manufactured to the high quality level of other Tower Pro servos. Vorpal MG90 Servos: These are our own brand of MG90 sized servos. ![]()
