A team of five mechanical engineering seniors, in collaboration with the Modular Robotics Laboratory and under the guidance of Dr. Mark Yim, have designed a search and rescue research platform intended to address limitations of current search and rescue robots and introduce a novel form factor and integration technique into the field. The system of [...]
Docking and undocking are common activities for robots (modular robots in particular). The relative frequency of this operation behooves us to ensure reliable alignment under uncertain conditions. We present a new face geometry that is numerically superior to existing alignment geometries. This geometry is intended for two-dimensional reconfigurable robots.
Connection mechanisms are critical to modular reconfigurable systems. The ModLock manual connection system is both fast to attach/detach and strong. This low cost, low profile connection system has been demonstrated on a variety of robot configurations including legged walkers, flying quadrotors and wheeled robots.
The design of this system called SMORES (Self-assembling MOdular Robot for Extreme Shapeshifting) is capable of rearranging its modules in all three classes of reconfiguration; lattice style, chain style and mobile reconfiguration. Modules are independently mobile and are capable of self-assembly from a collection of disconnected modules.
Hard foam can be used to synthesise a body on-the-fly, allowing us to spray a body for this quadruped. Each of the limbs comprises three CKBot modules, in a configuration similar to that used in the self-assembly after explosion project.
Can small man-portable robots aid the transport of incapacitated victims? This work received the Best Paper Award at the 2009 IEEE International Workshop on Safety, Security, and Rescue Robotics.
The factory floor is an experimental robotic system for the construction of passive robotically-reconfigurable truss structures. The macroscopic goal of this work is to embed autonomous reconfigurability into human-built systems.
The CKbot (Connector Kinetic roBot) is a chain style modular robot. It is designed to be fast and inexpensive while small enough to fit inside a 3 inch tube. It is manually reconfigurable into any shape while also allowing attachments such as wheels, grippers, IR proximity sensors and camera modules.
A car bumper is designed to crumple upon impact and protect the driver. A ski boot will detach from the ski to prevent injury to the ankle. Likewise a CKbot assembly falls apart when it is kicked, however CKbot can put itself back together again.
CKBot is designed to be fast allowing it to achieve dynamic locomotion. Given that CKBot is reconfigurable gives us the unique ability to research different types of dynamic locomotions in different morphologies all with the same hardware.
An advantageous feature of modular robots is the applicability to system fault tolerance. With redundant units and parallel processing facilities, modular robots have the capability or potential to account for certain types of failures within its system. This research presents work on communication fault tolerance with CKBot.
The advantage of reconfiguration is central to modular robotic systems. With this benefit, however, comes a complex and interesting challenge: how does a modular robot recognize which shapes are useful or familiar? The ability for a modular robot to determine which configurations are needed for various tasks is a fundamental requirement for increased autonomy.
