A New Nonlinear Dynamic Speed Controller for a Differential Drive Mobile Robot.

A disturbance/uncertainty estimation and disturbance rejection technique are proposed in this work and verified on a ground two-wheel differential drive mobile robot (DDMR) in the presence of a mismatched disturbance. The offered scheme is the an improved active disturbance rejection control (IADRC) approach-based enhanced dynamic speed controller. To efficiently eliminate the effect produced by the system uncertainties and external torque disturbance on both wheels, the IADRC is adopted, whereby all the torque disturbances and DDMR parameter uncertainties are conglomerated altogether and considered a generalized disturbance.

Data Transmission Enhancement Using Optimal Coding Technique Over Channel for Interbody Communication.

Wireless actuators and sensors are examples of sophisticated technologies. Another breakthrough is the use of wireless medical devices, which provide scalable and cost-effective solutions for wearable device integration. wireless body area networks devices reduce surgery invasiveness and provide continuous health monitoring.
