The broad research objective of the Assistive Robotics and Manipulation Lab is to develop technology that improves everyday life by anticipating and acting on the needs of human counterparts. We specialize in developing intelligent robotic systems that can perceive and model environments, humans and tasks and leverage these models to predict system processes and understand their assistive role. The research can be divided into the following sub-categories: robotic assistants, connected devices and intelligent wearables. We use a combination of tools in dynamical systems analysis, control theory (classical, non-linear and robust control), state estimation and prediction, motion planning, vision for robotic autonomy and machine learning. Our lab focuses heavily on both the analytical and experimental components of assistive technology design. While our application area domain is autonomous assistive technology, our primary focus is robotic assistants (mobile manipulators and humanoids) with the goal of deployment for service tasks that may be highly dynamic and require dexterity, situational awareness, and human-robot collaboration.
Improving Robotic Assistant Dexterity
As robotic assistants operate in complex, unstructured human-centered environments it becomes essential that robots
1. Have access to as much useful data as possible as they interact with the environment
2. Be able to leverage that data using intelligent models of the environment
Challenges for long term deployable robotic systems are
- Being able to handle uncertainty in a known environment
- Being able to reason about the properties of a new object/element in their environment
- Recovering from failure to complete a task/objective
By equipping robots to handle these challenges, we can develop robotic platforms that are capable of sustained, reliable, long-term service deployment.
Intelligent Prosthetic Arm (IPArm)
Prosthetic arm users often struggle to control their prosthesis, and accuracy is a skill that is developed over a long time period if it is ever achieved. Can a robotic prosthetic leverage situational awareness and prediction to decrease the learning curve and improve accuracy?
Smart Belt: Human Motion Prediction and Fall Prevention from Wearable Sensor
Dynamic bipedal walking is challenging to model as well as replicate on robotic platforms. Most exoskeletons use body sensors (surface EMG’s, subdermal, etc.) to predict leg motion, but the observation of the environment can reduce the need for invasive sensors and provide a longer prediction horizon.
