Capabilities

RPL’s extensive capability goes beyond hardware
and software to deliver next generation
products and processes.

Cooperative operation and integration between multiple hardware and software segments is one of our key abilities and is often critical to high level operation. RPL develops and commercialises comprehensive systems that are tailored to industry requirements through extensive client and relevant industry consultation. From technology validation, computer 3D design, prototyping, development, integration, commercialisation, right through to commercial production, RPL has extensive capability to cover most technological requirements.

Electromechanical
Electromechanical

Electromechanical or mechatronic systems are those that have both mechanical structures and incorporated electronics. The electronics provides control and/or monitors any mechanical movement or physical variable (e.g. temperature or direction). These systems include motors, compasses, gyros, or even large multi-axis anthropomorphic arms.

Robotic arms (manipulators)

The ability to develop task specific robot arms provides a large advantage to solving complex automation problems and increases commercially viability. Often off-the-shelf arms are not suitable due to size, performance and/or cost restraints. By custom designing our own robots RPL can remove previous barriers to automation. This capability includes several other areas including, mechanical, electronics and kinematics (mathematical description of movement). These manipulators could be a basic single prismatic (linear) axis carriage, Cartesian robots, SCARA (Selective Compliant Assembly Robotic Arm) robots, or even more complex large multi-axis anthropomorphic robots. All of these designs have their own comprehensive embedded control systems.

Servo systems and control

A servo system has integrated feedback and control to ensure that an action is being carried out as commanded. These systems include:

  1. Motors
  2. Pneumatics
  3. Hydraulics

Stepper motors and control

Stepper motors offer a cost effective option over servo motors for many applications. By incorporating motion encoders and custom electronic control, RPL can achieve cost effective servo systems from stepper motors for many control applications, including arms.
