Designing a Brushless Quadruped Robot

Brushless motors are changing the landscape in robotics. Coupled with precise closed-loop control, they are able to deliver excellent power to weight ratio but most importantly, they are transparent in the sense that external forces acting on the mechanism are reflected on the motor and vice versa. This leads to mechanisms that are actively compliant,

On ankle mechanics

Stand up on your toes. If you stay there for a while you’ll feel your calf muscles tension. Precisely how much force are the calf muscles exerting on your feet? This is an important question in designing humanoid robots, as the answer largely affects component and motor sizing of the robot. The human foot, simplified

3D Printed, Endurance Micro Quad

This post outlines the build of a micro quad that’s been designed with endurance in mind. I designed and 3d printed the quad parts to fit micro DC motors, prop gears and all relevant electronics, with reduction of weight being a prime objective.

3D Printed Landsail with Rigid Wing

This post outlines the design, printing and assembly of a 3D printed landsail with a rigid wing as a sail. Landsailing is a sport that applies the principles of sailing to land vehicles for propulsion. A lightweight wheeled vehicle is fitted with a mast and sail which uses wind-induced lift to provide thrust to the

On ESC Protocols Part II

In the first part of this post series we went over the most common ESC protocols that have been in use up until today. These protocols for the most part still dominate the market. In the second part we are looking at more recent protocols that attempt to tackle issues such as latency, refresh rate and
