A robotic cart platform with a navigation and movement system that integrates into a conventional utility cart to provide both manual and autonomous modes of operation. The platform includes a drive unit with drive wheels replacing the front wheels of the cart. The drive unit has motors, encoders, a processor and a microcontroller. The system has a work environment mapping sensor and a cabled array of proximity and weight sensors, lights, control panel, battery and on/off, 'GO' and emergency stop buttons secured throughout the cart. The encoders obtain drive shaft rotation data that the microcontroller periodically sends to the processor. When in autonomous mode, the system provides navigation, movement and location tracking with or without wireless connection to a server. Stored destinations are set using its location tracking to autonomously navigate the cart. When in manual mode, battery power is off, and back-up power is supplied to the encoders and microcontroller, which continue to obtain shaft rotation data. When in autonomous mode, the shaft rotation data obtained during manual mode is used to determine the present cart location.

A therapeutic pressure applicator with a sensor and transceiver is worn by a patient during daily activity to apply pressure to a specific body part, and used in a system with a device such as a cell phone to receive and display real-time pressure data to alert the patient and physician when the pressure is outside a desired range. The applicator includes a securement member and a pressure adjusting device with a pressure adjusting dial, pressure sensing component, pressure focusing plate and cushion. Rotating the dial retracts or extends the sensing component, focusing plate and cushion. The applicator has a computer module with a CPU, memory, transceiver, power source and a force sensor. A pressure button is pressed into engagement with the sensor to transmit real-time focused pressure data to the CPU. The transceiver communicates the real-time cushion pressure data to the cell phone that displays and stores the data.
