Energid develops software for simulation and
control of any robotic system.
Actin software is at the core of our
business:
• Actin SDK
• Actin Applications
• Integration Services

Actin Software
• Multi-robot coordination
• Dynamic collision avoidance
• Singularity avoidance
• Kinematically redundant mechanisms
• Complex kinematic chains
• Global path planning
• Real-time dynamic simulation
• IO and sensor feedback
• Easy integration of new hardware
components
• Integration with CAD
• Desktop applications for Windows,
Linux, OS X
• Control on VxWorks, Real-Time Linux
and RTOS32
• Distributed processing over DDS
Simulation and control software for any robotic system

Actin Software
Actin is a high level robotics control framework
One column for each robot
(executed on separate machine)
Task building
blocks
Multi-robot tasks can be created on one machine and
executed on many

It was customer driven:
• Many government customers began emphasizing DDS
• Single-robot deployments
• Increasing demand for “remote” capability
• Multi-robot deployments
• One robot controller machine per robot
• Communication between the controllers consists of:
• Commands, state synchronization, sensor feedback, hardware status
• Safety and mission critical systems
Learned first hand that developing and maintaining our own
communications middleware was going to be cost prohibitive.
Why did Energid adopt DDS?
Copyright 2016 Energid
• There is a trend towards higher-level frameworks
• Joint-level control to end-effector control to path planning
• Traditional socket IPC to DDS
• Message contents and delivery are independent
• Powerful Quality-Of-Service (QOS) options
• Multiple communication channels (unicast, multicast, shared memory)
• Message is the “what”
• QOS determines “if”, “when”, “where”, and “how”
• Redundancy and fail safety
• Allow redundant processes running in parallel
• Respond to critical system events (liveliness, latency, etc)
• Simplify complex communication problems (Security)
• Reduce development time
Why use DDS for robotics?

Universal Robots Collision Avoidance Demo
Robots dynamically avoid collisions with themselves and the environment.
Communication of robot joint state and
status is time critical.
If one robot protective stops, then the others
must know and respond.
