Usually when you think about “robot videos”, you think about blockbuster movies like Transformers, Wall-E, Short Circuit, Real Steel and others. You would be surprised however to see just how many free robot-themed animated / CGI short movies are out there, many of which could easily be misconstrued as short clips taken from much longer […]

When we first saw Robotis release their new line of professional (and large) Dynamixel Pro servo motors, we knew it would not be long until they were used to create larger humanoids. So, not long after their release, “THOR” was revealed; Robotis’ child-sized humanoid entry into the DARPA humanoid challenge. The latest iteration of this […]

We would like to thank Chris and Jim from Project Lead The Way (PLTW) for creating several videos around the Lynxmotion Servo Erector Set  (SES) V1.1. Videos are one of the best ways to get a good understanding of a product. This set of seven videos include unboxing / package contents of the SES V1.1, […]

This tutorial is intended to complement the Robot Arm Torque Calculator found in the Dynamic Tools section of GoRobotics. The equations used in the calculator to determine the torque required at any given lifting joint (raising the arm vertically) in a robotic arm are presented here. Note that the term “actuator” is used rather than motor because […]

A Motor Controller is a device that acts as intermediary between your robot’s microcontroller, batteries and motors. A motor controller is necessary because a microcontroller can usually only provide roughly 0.1 Amps of current whereas most actuators (DC motors, DC gear motors, servo motors etc.) require several Amps. The current a motor consumes is related to […]

An actuator is a device that converts electrical energy into physical motion. Choosing the right actuators (which include DC motors, gear motors, servo motors, linear actuators, muscle wire etc.) requires an imagination and a bit of math and physics. The vast majority of actuators produce either rotational or linear motion though combinations thereof can lead to complex motion.

There are many different ways to communicate with a robot. Robots are most often controlled using a tether (wired), wirelessly or autonomously. Tethered The easiest way to control a robot is using a handheld controller connected physically to the robot using wires or a cable. Toggle switches on the controller allow you to control the […]
