Continuous Rotation Servo

The latest continuous rotation servo from ServoCity is based around the popular Hitec HSR-2645CRH, but with a 25 tooth output spline in order to conform with the majority of the hobby servo market. The servo also boasts an M3 x 0.5 mm socket head servo screw for additional holding power and ease of use. Similar to the HSR-2645CRH, this servo rotates at a specific speed based on the signal received from the servo controller. Its speed is fully proportional, meaning that the further the signal deviates from the center (1,500 µsec), the faster the servo will rotate.

It can be difficult to control the speed of regular servos that have been modified to continuous rotation. However, the HSR-2648CR circuit was designed from the factory to drive the servo smoothly and with fine-control over the speed. Since the HSR-2648CR servo is digital, it’s able to be tuned using a Hitec servo programmer. The programmable parameters allow you to tailor the servo to best fit your application. This servo is excellent for compact sliders, winch mechanisms, small panning devices, and wheel-drives on robots. Price is $32.99.

1/4” D-Bore Barrel Hub

ServoCity’s new 1/4” new D-bore barrel hub is a balanced clamping hub that maximizes surface contact on the shaft to provide superior holding force when compared to a standard clamping hub.

The increased barrel length also aids in handling greater radial loads. The dual pinch bolts are tucked in tight to minimize the clearance diameter as the hub rotates within an assembly. Patents pending. Price is $6.99.

Steel 1/4” D-Bore Barrel Hub for Worm Gears

This D-bore hub also from ServoCity is designed to be used with a 27 tooth worm gear or a 26 tooth bevel gear. While both have the potential to be demanding on a hub, it’s the worm gears that have driven this hub to being made of steel with huge 8-32 pinch bolts.

With the 27:1 ratio gear reduction of the worm, there’s potential to generate massive amounts of torque. With the combination of the D-bore, the steel body, and large fasteners, there’s little chance in having this hub slip, strip, or fail even in the most rigorous application. Price is $6.99.

Custom Badge Kit

Addicore has introduced the “Custom Solder On! Badge AddiKit:” a product that allows groups of all kinds to include basic electronic assembly and soldering into their meetings, seminars, gatherings, or activities.

When individually custom marked with the group’s name and/or message, the completed kits can be worn during and after the event to generate name recognition, positive feedback, and added confidence for group members who have leveled up in a much-prized skill.

The “Custom Solder On! Badge AddiKit” consists of:

  • 1 Solder On! printed circuit board that has a group’s specific logo and/or slogan on it
  • 1 Fast color changing RGB LED light
  • 1 Through hole resistor
  • 1 Switch
  • 1 2032 coin cell battery holder
  • 1 2032 coin cell battery
  • 1 Pin back with double-sided tape (so the completed project can be easily worn)

A Solder On! Badge AddiKit project is very easy for kids of all ages to complete with a modest investment of time and energy. Only a soldering iron, solder, and supervision must be provided by the group. Small children will benefit from having an older tween/teen or an adult to help with the use of the soldering iron during final assembly.

Here are abbreviated instructions: Solder the RGB LED light in place. Then, install and solder the resistor, the switch, and the battery holder. The circuit board has information printed on it to help with each of these steps. With the switch in the “OFF” position, place the unit’s battery into the battery holder, then wait until the participant flips the switch. The RGB LED light will cycle through numerous colors to signal a successful project completion.

Smart Servos

The new Lynxmotion Smart Servos (LSS) from RobotShop are compact, modular, and configurable actuators designed to be an evolution of the standard RC servo for use in multi degree-of-freedom robotics, animatronics, custom RC projects, and more.

The servo lineup currently includes three “smart servos” which appear physically the same, sharing the same dimensions, mounting points, and output spline, but differing in maximum torque and speed.

The servos are core modules of the next generation Lynxmotion Servo Erector Set (SES) modular robotic construction system and a wide variety of modular brackets, mechanics, and electronics have been designed around them. “Smart” means each servo’s parameters are user modifiable and configurable; there is sensor feedback; built-in safety features; and although meant to be connected to a microcontroller, can be used as advanced RC actuators.

The custom LSS serial communication protocol was built on the SSC-32/32U protocol and makes communicating with, controlling, and configuring the servos easy and intuitive.

Features include:

  • Serial, RC PWM, and continuous rotation modes.
  • Human-readable LSS serial communication protocol.
  • Button menu, RGB LED.
  • Feedback: Voltage, current, position, temperature, operating status, and more.
  • Configurable: Center position, angular range, direction, speed, and much more.
  • All metal gears for high torque and reduced wear.
  • Libraries: Arduino, Python, ROS.
  • 12V nominal (3S LiPo ideal), 6-12V operation.*
  • Standard 24T output spline (compatible with accessories made for Hitec 422, 645MG servos).
  • Many mounting points, brackets, accessories.

* Note that the servo’s maximum speed and available torque both decrease with lower input voltage.

The easiest way to differentiate between the three models is based on the sticker, located at the rear of the servo. Lynxmotion software automatically determines which model is connected.

Detailed product specifications regarding voltage, torque, speed, temperature, and more can be found on the LSS - Specifications page.

Also note that these servos are intended primarily for hobby, educational, and semi-professional use. They are not intended for industrial, medical, or related applications, and are not certified as such.

The servos are meant to be powered from either a battery source or a DC wall adapter. When selecting a power source, ensure it will be able to provide sufficient current to power all of the servos in the project.

The “high speed” and “standard” models are the same price ($67.99) whereas the high torque is $109.95.
