I've been working for the past couple of weeks on the nosewheel doors. In the course of testing the actuation system, I found that in three years of operation the connection between the main and the nose actuators -- all three struts' retractors are mechanically interlinked -- had developed some play. The bellcrank tha...

Based on the rotor position, two sinusoidal waveforms are created, 120 degrees phase shifted from each other. Multiplying these signals by the torque command produces amplitudes that are proportional to the desired torque. These commands are fed to the controller, which regulates the current in the motor windings. Acco...

The challenge of synchronization, specifically addressing the phase offset between transmitter (Tx) and receiver (Rx), can be mitigated by using differential measurements. By analyzing the phase difference Δ​ϕ=ϕ2−ϕ1\Delta\phi=\phi_{2}-\phi_{1} between two carriers of wavelengths λ1\lambda_{1} and λ2\lambda_{2} propagat...

The pose of a Swedish wheel is expressed exactly as in a fixed standard wheel, with the addition of a term,  , representing the angle between the main wheel plane and the axis of rotation of the small circumferential rollers. This is depicted in figure 3.8 within the robot’s reference frame. Formulating the constraint...

Air ducts are integral to modern buildings but are challenging to access for inspection. Small quadrotor drones offer a potential solution, as they can navigate both horizontal and vertical sections and smoothly fly over debris. However, hovering inside air ducts is problematic due to the airflow generated by the rotor...

After the covariances are set, it is useful to evaluate the performance of the filter; i.e., whether it is possible to improve the state estimation quality. If the Kalman filter works optimally, the innovation sequence (the output prediction error) is a white noise, therefore the whiteness property of the innovations) ...

Impression of Ed’s 3D animated hand The computers of the time weren’t capable of calculating an entire frame of footage at once, so the output on the screen was captured with a long-exposure camera until the entire frame was processed. When this was done, a snapshot would be taken. A lot of work for just one frame. The...

If you are working with ESCs for high current applications, be aware of component (MOSFET and diode) lead sizing and the total current your system will draw.  Once you get over 20A or so, precautions must be taken to ensure that everything can handle the current without overheating.  This applies to PCB traces and comp...

Expectation maximization algorithms may be employed to calculate approximate maximum likelihood estimates of unknown state-space parameters within minimum-variance filters and smoothers. Often uncertainties remain within problem assumptions. A smoother that accommodates uncertainties can be designed by adding a positiv...

Firstly, boundaries were introduced for the Cartesian space components to optimize the attraction field function, such that regardless of the difference between the initial pose and the target pose, the redundant robotic arm s end effector can now reach the target pose at a consistent speed.

The period around Christmas and New Years brings work on the plane practically to a halt. I did squeeze in a few hours to reposition the oxygen on-off lever, which turned out to collide with the sidestick after I moved the latter a few inches aft. I also started cutting material for an armrest, which I think will make ...
