Research Overview

Line: 7 to 7
 Currently our research focus is centered around "modeling of biological systems" (mathematical formulations of animals' adaptive behaviors), "self-organization" (mechanisms to generate structures and patterns), and "component development" (development of unconventional enabling technologies such as sensors, motors, computation algorithms and assembling technologies). By understanding the basic design principles of these technological components, we aim to deepen our understanding of self-organization processes of intelligent adaptive behaviors in animals and machines.

Amazon Robotics Challenge: Cambridgearm Team

Picking and place into boxes from shelving remains one of the key challenges in a warehouse environment. As a driver for research, we are competing on the Amazon Robotics Challenge focusing on the development of robust vision systems, determing relevant gripping points and developing an adgile manipulator to allow manipulation of a number of items.

Thermoplastic Adhesives in Robotic Locomotion and Manipulation

 
glue.jpg

Description: Robotic growth and morphological change will increase the adaptability of a robotic system facing unanticipated task-environments. The research area focuses on development of mechanisms for robotic growth and morphological change based on Thermoplastic Adhesives (TPAs), also known as ‘hot glue'. TPAs are economic, off-the-shelf, and they have several interesting properties. They can form flexible or rigid structures by means of existing fast-prototyping techniques and can be also used as an easy and strong connection mechanism, which are important technologies towards robotic growth and morphological change.

Emergence of Reflexive Behavior: a Developmental Approach
legmodel3d.png Description: Developmental robotics is located at the intersection of developmental sciences and robotics. The main goal of this field of research is to investigate how a creature can develop increasingly complex behaviors autonomously. In this particular project we use self-organization principles to develop reflexive behavior in a simulated leg model. Using the same self-organization principles, we have obtained analogues of the myotatic, the reverse myotatic, the reciprocal inhibition, and the withdrawal reflexes, which have been identified in the mammal spinal chord.

Assistive Mechatronic Posture Support
Project_noonee.jpg Description: Using passive and low energy components the goal of this project is to develop a power efficient and comfortable posture support device which allows the user to stand for long periods of time as well as walking and climbing stair. The device absorbs the body weight of the user and redirects it away from the knee. This reduces the stress on the knees and muscles and therefore the risk of pain and injuries. The device is equipped with a high performance variable hydraulic damper. The damping can be varied from very low to very high damping and ultimately brake. The control of this damper allows different applications of the device in the industrial, rehabilitation and medical field.

Research Overview

The research interests of the Bio-Inspired Robotics Lab lie at the intersection of robotics and biology. Through abstraction of the design principles of biological systems, we develop core competences which are the design and control of dynamic mechatronic systems, bionic sensor and actuator technologies, and computational optimization techniques. Our main goals are to contribute to a deeper understanding of adaptivity and autonomy of animals through the investigation of dynamic robots, and to engineer novel robotic applications which are more adaptive, maneuverable, resilient, and energy efficient.

Currently our research focus is centered around "modeling of biological systems" (mathematical formulations of animals' adaptive behaviors), "self-organization" (mechanisms to generate structures and patterns), and "component development" (development of unconventional enabling technologies such as sensors, motors, computation algorithms and assembling technologies). By understanding the basic design principles of these technological components, we aim to deepen our understanding of self-organization processes of intelligent adaptive behaviors in animals and machines.

Simulation of Multi-Mode Linear Actuator (MMLA)
stairs_200.jpg Description: Legged locomotion on rough terrain is a demanding task which requires both the mechanical design and the control of a system to be versatile and adaptive.

Self-Sufficient Legged Robot in Uncertain Environment
xianshengchi3.png Description: Previous projects on self-sufficient mobile robots have shown that dealing with uncertainties of the real world is a challenging problem. This project focuses on efficient approaches applicable in real world scenarios with the objective of finding practical behavior to cope with uncertainties where classical approaches such as simulations fail. In a first step a simple self-modeling approach has been used to find gait patterns for forward locomotion and rotation. Augmentation of two cheap sensors - a proximity and beacon sensor - have shown satisfactory navigation behavior towards the charging station in a simple environment.
