Barobo‘s Linkbot all-in-one smart actuators allow anyone without any knowledge of robotics to create and “program” robots. Each actuator is packed with many features including: • Atmel AVR Microcontroller: Compatible with Arduino so you can re-flash with your own firmware using the on-board bootloader • ZigBee-Capable Radio: Communicate wirelessly with an 802.15.4-compliant radio, create mesh […]

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 […]

The Robot Leg Torque Tutorial is intended to compliment the RobotShop Leg Torque Calculator found in the Dynamic Tools section of the RobotShop Learning Center. This tutorial explains how to find the torques acting at each degree of freedom of a 6-legged (hexapod), 3DOF / leg “insect” robotic leg. Hexapod (6-legged) robots are most commonly […]

Here’s how to modify a servo for continuous rotation. If you’re building a robot, one of the first things that you need to think about, is how you are going to propel it. There are many different choices for this, including fans or propellers for a boat robot, props or turbines for a flying robot, or legs for […]
