About

Tapesh is an undergraduate engineering student at BIET Jhansi with a working interest in drone systems and aerial mapping. He coordinates The Drone Learner's Club, where students build, fly, and study unmanned aerial platforms.

Before BIET, he spent time at IIT Patna studying computer science and data analytics, and at GBP Engineering College in mechanical engineering — collecting technical range before settling into his current trajectory.

He has trained at IFFCO's Aonla plant on industrial processes including distillation columns and shell-and-tube heat exchangers. He holds a core membership at the Bureau of Indian Standards, serves as a liaison in the BIET Alumni Association, and teaches underprivileged children through SEWA.

He represented IIT Roorkee's E-Summit as a campus ambassador and volunteered at the Bundelkhand Innovation and Incubation Center. He is a UP Scholarship recipient and has been certified by Canara Bank for investment knowledge.

His work sits at the intersection of drone technology, process engineering, and student-led innovation.

Flight Dynamics

The mathematics governing quadrotor flight — from individual rotor thrust to full six-degree-of-freedom attitude control. These equations inform every aspect of platform design, from motor selection to PID tuning.

Rotor Thrust

Ti = kT · ωi²

Each rotor generates thrust proportional to the square of its angular velocity. kT is the thrust coefficient determined by blade geometry and air density.

Hover Equilibrium

ΣTi = mg  ⇒  4kTωh² = mg

At hover, total thrust from all four rotors exactly balances gravitational force. This defines the baseline angular velocity for stable flight.

Net Torque (Yaw)

τz = kD1² − ω2² + ω3² − ω4²)

Yaw torque arises from differential drag between CW and CCW rotor pairs. kD is the drag coefficient of each blade.

Roll Moment

τφ = L · kT4² − ω2²)

Roll is generated by thrust differential between left and right rotor pairs, scaled by arm length L from the center of mass.

Newton-Euler (Translational)

m · a = R · Fthrust − mg · e3 − Fdrag

Translational dynamics in the world frame. R is the rotation matrix from body to world frame. The thrust vector is rotated by current attitude before summing with gravity and aerodynamic drag.

Rotation Matrix (Z-Y-X Euler)

R = Rz(ψ) · Ry(θ) · Rx(φ)
φ : roll    θ : pitch    ψ : yaw

Attitude is parameterized using Tait-Bryan angles. The rotation matrix maps body-frame forces and torques into the inertial reference frame.

Euler's Rotation Equation

I · α + ω × (I · ω) = τ

Rotational dynamics relating angular acceleration to applied torques, accounting for gyroscopic coupling via the cross-product term.

PID Control Law

u(t) = Kp · e(t)  +  Ki · ∫0t e(τ) dτ  +  Kd · de(t)dt
where   e(t) = r(t) − y(t)   |   r: setpoint    y: measured state

Each axis (roll, pitch, yaw, altitude) runs an independent PID loop. Gains Kp, Ki, Kd are tuned per-axis to achieve stable, responsive flight without oscillation.

Reference frame conventions follow NED (North-East-Down). Rotor numbering is clockwise from front-right. All equations assume rigid body dynamics with negligible blade flapping. Aerodynamic coefficients are empirically determined through static thrust testing.
