We have a new machine in our lab! It is a laser cutter, which can be employed in both carving and cutting works. This laser engraver is equipped with one 40W water cooling laser tube, high precise stepping motors, high quality control board. It employs an USB port and thus can be connected to your l...

Research on how to measure/estimate reaction torque

In addition to thrust force, a spinning propeller will also introduce reaction torque onto system. According to paper [1], there is a strong linear relationship between a propeller’s reaction torque and thrust force. Once this relationship is f...

The following is a short overview of the process by which the characteristic velocity of the vehicle is determined from local information. Let $v(t)$ be the velocity of the vehicle at time $t$. In the presence of traffic jams, $v(t)$ will be wave like. A sample of different possible solutions...

Simulate Motor Thrust in Simulink

On Crazyflie, the spinning of motor and propeller will introduce a thrust onto the system. According to Crazyflie Wiki page (https://wiki.bitcraze.io/misc:investigations:thrust), the relationship between the motor spinning speed (rpm) and the thrust force (g) can...
