This paper discusses an idea for torque and speed modulation in rotating-blade systems. This can be done by magnetizing the blades of the system in a particular manner and keeping an electromagnet at the base of it. The base electromagnet and the magnetized blades interact appropriately to produce the required speed/torque modulation. Using the principles of electromagnetic interactions, it has been...
Back-To-Sit and Sit-To-Stand movements are the most important and essential movements for any human being to sustain their life and to accomplish their habitual actions. Not only for human beings, but for robots or assistive devices to accomplish several tasks, these movements are vital. The knee joint has the major functionality to execute such movements and indeed, the torque required at these joints...
This paper describes the selection of brushless motors, propellers and battery for getting maximum time of hover for a quadrotor UAV. We also introduce a experimental testbed to measure various parameters of the system like torque, thrust, RPM, current and voltage. The static testbed is directly interfaced through MATLAB for real time data acquisition. We tested different motor and propeller combinations...
The purpose of this paper is to present a brief comparison between a conventional hexacopter and a cant angle hexacopter. A conventional hexacopter has got all its 6 rotors fixed and thrusted upwards in the body frame which gives it a decoupled 4 DOF motion or a coupled 6 DOF motion. But a cant angle hexacopter has all its six rotors canted at an angle tangentially to the radius of the frame. It provides...
