Overview
Use of hybrid architecture combining an
MPC5xx microcontroller unit (MCU) and two
to three TouCAN™ modules can be used in
applications from toys to industrial
manufacturing. Each node on a robotic arm
application has a stand alone functioning
module designed to enable modular
construction, leading to adaptable robotic
arms. Nodes include sensors designed to
gauge temperature, pressure, and position
allowing feedback to the central control unit.
Up to 32 nodes can be driven from one
embedded controller.
The MPC500 embedded microcontrollers
are ideal for control intensive applications
like the robotic arm. Compatible with the
PowerPC ISA instruction set architecture,
these devices are available with two or
three TouCAN™ modules capable of
sending control signals to CAN drivers (one
for each TouCAN™ module). The systems
communication is essentially achieved
between two lines with a CAN 2.0B
protocol. Each CAN driver is engineered to
be able to drive up to 32 nodes across an
entire robotic application. The nodes are
designed to independently deliver control
commands to motors or actuators, or send
and receive sensor information about the
robot, or the surrounding environment.
Imagine a cave exploration robot rolling
downward into a rough, dark terrain. It
examines a rock with a remote controlled
arm—scratching the surface and detecting
compounds. Next, the robot plunges into a
liquid pool. Sensors on the arm inform the
central processor the liquid is di-hydrous
oxide (water), and proceeds to the next
observation.
