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,

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

Fully Autonomous Robocar

The last updates in the Burro autonomous robocar platform focus on two areas: Collaborative driving and fully autonomous driving (steering and throttle). Collaborative driving allows control of a single vehicle using multiple controllers and a self-driving model, all at the same time. Using this feature, one may have a neural network control the steering and

Autonomous driving at the micro scale

Building and training a self-driving robocar takes several iterations of hardware and software improvements. Especially training a competitive model is a time consuming process that involves going back-and-forth to the track several times to either check or improve model predictive performance by recording additional samples. Computer simulation is an alternative, however setting up a simulation

Emulating an Ackermann Steering Vehicle

Two steering schemes are mostly popular when it comes to ground vehicles: Differential, or skid steering, and Ackermann steering. Differential steering vehicles, despite their fancy name, look just like the typical two-wheel robot chassis found pretty much everywhere: Differential steering vehicles, as the name suggests, use differential thrust to turn. Most are made of two wheels

Building a DIY sub-500 gram quadcopter

In a previous post I’ve discussed the advantages of a lightweight aircraft: longer flight times, quieter operation, less stress to the components, more responsive control. In addition, having an aircraft below 500 grams (less than around 1.10 pounds) has the advantage that in many countries it does not require registration to fly, except for where
