DESCRIPTION
The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with five low-power
modes, is optimized to achieve extended battery life in portable measurement applications. The device features a
powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 μs.
The MSP430G2x13 and MSP430G2x53 series are ultra-low-power mixed signal microcontrollers with built-in 16-
bit timers, up to 24 I/O capacitive-touch enabled pins, a versatile analog comparator, and built-in communication
capability using the universal serial communication interface. In addition the MSP430G2x53 family members
have a 10-bit analog-to-digital (A/D) converter. For configuration details see Table 1.
Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values,
and then process the data for display or for transmission to a host system.

The BTS5016SDA is a one channel high-side power switch in PG-TO252-5-11 package providing embedded
protective functions.
The power transistor is built by a N-channel vertical power MOSFET with charge pump. The design is based on
Smart SIPMOS chip on chip technology.
The BTS5016SDA has a current controlled input and offers a diagnostic feedback with load current sense and a
defined fault signal in case of overload operation, overtemperature shutdown and/or short circuit shutdown.

The AZ1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current.
The AZ1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 5.0V and adjustable versions or 2% for 1.2V version. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature.
The AZ1117 has an adjustable version, that can provide the output voltage from 1.25V to 12V with only 2 external resistors.

obot control, a subject aimed at making robots behave as desired, has been
extensively developed for more than two decades. Among many books being
published on this subject, a common feature is to treat a robot as a single
system that is to be controlled by a variety of control algorithms depending on
different scenarios and control objectives. However, when a robot becomes more
complex and its degrees of freedom of motion increase substantially, the needed
control computation can easily go beyond the scope a modern computer can
handle within a pre-specified sampling period. A solution is to base the control
on subsystem dynamics.

Internet of Things (IoT) [26] is a new networking paradigm for cyber-physical
systems that allow physical objects to collect and exchange data. In the IoT, physical
objects and cyber-agents can be sensed and controlled remotely across existing
network infrastructure, which enables the integration between the physical world
and computer-based systems and therefore extends the Internet into the real world.
IoT can find numerous applications in smart housing, environmental monitoring,
medical and health care systems, agriculture, transportation, etc. Because of its
significant application potential, IoT has attracted a lot of attention from both
academic research and industrial development.
