Competitors to Dynamixel XL-320? Like RC servo but 2 way digital coms
.Stack entry by James Newton
What servo out there - is near an RC servo form factor e.g. about 1 or 2 inches in physical size. (the current servo is 1"x1.4"x0.7" ) with a shaft takeoff - has a digital interface that can BOTH - accept command to move with a specific torque / drive...

First leg prototype
Log from Mildred the Hexapod
2019-03-08 Made a first leg prototype with the initial three servos I had. Starting with one leg gave me a chance to both test the tolerance and clearances on my 3d printed parts and experiment with the Dynamixel SDK early, before committing to buying...

Components
Instructions from Hexapod
Dynamixel AX-12A: The biggest problem on controlling hexapod is controlling its leg, and that is what makes choosing motors the hardest job for component part. What I'm planning to do in the future for controlling this hexapod is using dynamic...

Board prototyping
Log from Stack-chan - JavaScript driven super-kawaii robot
From recent tweets (2021-06-04) Stack-chan board prototyping on universal board. I've made a PCB board for translating between UART of M5Stack and TTL of serial servos. I tested the board with RS304MD serial servo. But theoretically it can apply to other...

Experiment #1
Log from Scarab - Hexapod Robot
Here is the first experiment with a robot leg and solving inverse kinematic problem algorithm. Software was written in C++ running ROS Kinetic. A marker was attached to the end of the leg in order to check correctness of the algorithm. Also reference...

Adding a Manipulator
Log from Wild Thumper based ROS robot
The WIld Thumper robot now has a 4 degrees of freedom (DOF) Open Manipulator with a RealSense D435 depth camera attached: The manipulator can be extended to 6 or more DOF if necessary. Communication with the Dynamixel servos is done with the AVR...

New Tool Interface
Log from Dexter
We have developed a new tool interface for use with Dexter. It provides more interactivity with a pair of Dynamixel XL-320 servos as a 6th and 7th axis. The 6th axis acts as a wrist and the 7th is available to power a gripper or other end effector/tool....

Control of Many Servos
Log from Dexter
While we were implementing the 6th and 7th axis onto Dexter, we realized that our FPGA servo control system is so fast, it should be able to operate over 200 servo motors at reasonable update speeds. We're not sure there is any application that could...

Friday
Log from K3lso Quadruped
Work is still in progress for all the covers. Spending much time to adjusting and fitting everything together. But slowly cooming together.Friday Picture: Wireframe of k3lso. Design is moving along nicely!Planned for two Dynamixel mx106 in head...

Arduino (OpenCM) Serial and Motor Command Code
Instructions from Quadruped robot with 22 DoF
This Arduino code allows the OpenCM9.04, together with OpenCM 458 Expansion Board, to receive commands via serial from the Python kinematics code, and in turn send the goal positions and speeds to the AX-12 motors. LegTestRig_OpenCM.ino...

Printable Quadruped Arduino & Raspberry Robot Spot
Details from Printable Quadruped Arduino & Raspberry Robot Spot
Enik robot is a quadrupedal robot designed for contribute to both students and researchers studies about the code information in a practical way. At the same time, this robot is a useful prototype to develop larger four-legged robot. 12 AX 12-A Dynamixel...

Actuator Testing
Log from 3D Printed Robot Actuator
Testing using the Brushless motor, Cycloidal gearbox, Position sensors, Controller and LiPo Battery 3kg of weights placed at 330mm distance from the center axis = 100kg/cm or 10NmThe laptop sends a command to move between 90 (vertically down) and 180...

Build your own TurtleBot 3 backbone
Details from Build your own TurtleBot 3 backbone
Why this project ? It makes no doubt that ROS (Robot Operating System) is the most common framework for robotics. It offers a powerful middleware for interconnecting sensors and actuators with already packaged drivers and state-of-the-art algorithms...
