We have developed a low-cost, lightweight coaxial-rotor MAV capable of full attitude control using just two actuators. The vehicle provides real-time telemetry and high-quality video to a ground station which can be used to remotely pilot the vehicle. The design integrates the underactuated rotor system developed in the lab with parts of cheap helicopter toys […]
We extract thrust, roll, and pitch authority from a single propeller and single motor through an underactuated mechanism embedded in the rotor itself. This allows new types of conventionally-capable micro air vehicles now requiring only two motors. This contrasts with the servos and linkages of conventional helicopters or the four drive motors in quadrotors.
We have built a system of shipping container sized robotic boats that can hook onto each other. We demonstrate the conceptual design of a system that is capable of constructing bridges and various shaped islands that can be made compliant to waves.
