Long Post Alert! IIT Delhi Tryst 2026 https://tryst-iitdelhi.org I had the opportunity to visit IIT Delhi for the Annual Robotics festival TRYST 2026, and didn't miss it even though it was right in the middle of my final exams. A few days' break in the exam schedule due to Holi helped as well. Though I only had a 3-hour window, I got the vibe: the participants, the energy, the displays, the seminars, and the competitions. I liked the following: 1. The ISRO Exhibition, with models of Chandrayaan-3 (1:15), GSLV Mk III (1:20) and PSLV (1:20). Chandrayaan-3 had achieved India's historic soft landing on the Moon's South Pole on August 23, 2023, making India the first nation to do so and the fourth country overall to land on the Moon. The mission successfully deployed the Vikram lander and Pragyan rover, completing all its scientific objectives, and demonstrating India's advanced space capabilities. The GSLV Mk III, now redesignated as LVM3 (Launch Vehicle Mark-3), i...
Let's talk about the statics of a human arm holding a weight. Let's try to calculate how many Newtons of Force is the biceps tendon carrying, and what is the moment in the shoulder joint? We assume that a person of 100 kg is holding a dumbbell weighing 10 kg. Thus, weight of the upper arm = approx 4% of body weight = 4 kg, and weight of the fore arm = approx 3% of body weight = 3 kg. We take the length of the fore arm = 30 cm. Also, for keeping calculations simple, we take g = 10m/s2. Cutting the system free F w1 = 40 N, F w2 = 30 N, F wd = 100 N α = 10 ° d 1 = 5 cm, d 2 = 15 cm, d 3 = 30 cm We can calculate Force on the Bicep, F B = 172.62 N Shoulder Moment, M A = 34.5 Nm This is fun!

The Inspiration Behind My Robo Hand Assist for Rehab Project! Some incidents have a deep impact on you. In December 2025, someone very close to me met with a horrible accident, suffered multiple injuries in the hands, legs, and hips, had to go through multiple surgeries, a long period in the hospital, followed by a long period of recovery. Among the injuries, one was particularly brutal, not because it was life-threatening, but because it took away control. He suffered a radial nerve injury, a condition that affects the ability to extend the wrist and fingers. In simple terms, the hand loses its ability to open and lift. This leads to something known as “wrist drop”, where the hand is unable to perform even the most basic actions. Holding a bottle. Picking up a pen. Shaking someone’s hand.Movements we never think twice about suddenly become impossible. What followed was a series of complex medical procedures - fracture fixation, nerve repair, and eventually a tendon transfer surgery. F...
