Arduino – Not detecting Arduino board.
If your board does not appear on a port in Arduino IDE………………… Ensure you’ve connected your board with a working data USB cable. Check that your device is powered. One or more LEDs should be lit. In earlier versions of Arduino IDE 2, the Tools > Port menu option would only be displayed if at… Continue reading Arduino – Not detecting Arduino board.
FORWARD KINEMATICS
Forward kinematics is a concept in robotics and computer graphics that involves determining the position and orientation of the end effector of a robot or an articulated system based on the positions and orientations of its individual joints. In other words, forward kinematics deals with mapping joint angles or joint parameters to the resulting pose… Continue reading FORWARD KINEMATICS
FLEX SENSOR-A Brief Overview
A flex sensor is a type of electronic component that changes its resistance when it’s bent or flexed. It’s typically made of a flexible substrate with conductive material applied on it. When the sensor bends, the distance between the conductive elements changes, altering the resistance of the sensor. This change in resistance can be measured… Continue reading FLEX SENSOR-A Brief Overview
HARMONIC DRIVE
A harmonic gear drive, also known as a strain wave gear or harmonic drive, is a type of gear mechanism that offers high precision, compact size, and high gear reduction ratios. It consists of three main components: a wave generator (flexible spline), a circular spline (flexible outer ring), and a flex spline (flexible inner ring).… Continue reading HARMONIC DRIVE
