First attempts to add cutouts to the interfaceThis week I continued my work with Wenzhong on adding finger joints as a option for creating output with Roco. We made some progress in figuring out how to create our own custom tabs as a method of adding the finger joints, however our current method...

This week I was finally able to assemble a paperbot model and bypass the scaling issues. The scaling issues themselves have not been solved but by measuring the paperbot that was previously made I was able to scale the printout manually on Silhouette Studio.I was also able to get my old component...

Last week, the SCP actuators were assembled into mechanical logic frame and tested. There are some challenges still needed to be solved to get the mechanical logic function. The first main issue is the contact betweeen SCP actuator and conductive tab. A much more reliable method should be proposed....

The Robot Operating System(ROS) is a set of software libraries and tools for building robotic applications. The ROS platform is a unified and well-documented framework for development with different kinds of robots. In the case of our project, ROS is chosen for modification of Crazyflie 2.0's contro...

Last week, I assembled the first prototype of the load cell system. It was able to read the force applied to the sensor and send the data to Arduino serial terminal. However, it's still a bit inconvenient to process the data like plotting or doing mathematic operations in the serial terminal. With P...

The research question that this investigation seeks to answer is whether its possible to localize a drone in two dimensional space using a one dimensional LIDAR or range finder. The investigation has two main aspects; hardware development and integration, and software and simulation. The progress in...

This past Friday, Christian Prathyush and I met with some of the newer members of our lab who are interested in working on RoCo. Before we completely move to a new project, we got together to discuss what RoCo's status would be by then. One of the topics discussed was the fairly fragmented nature of...

The 60GHz Tx RF pulse generator is the circuitry in the red box. The function of this block is to generate a 60GHz mm-wave pulse from the multi-phase 10GHz LO signals and deliver this RF power to the integrated 50Ohm antenna load. There are 3 main circuit blocks : a NAND gate logic frequency sy...

The interpretation of covariance intersection is based on its assumption of Gaussian distribution. Or we have to draw the covariance ellipse to illustrate the variation of such fusion. However, what happen to the fusion of other distribution?In this paper, they formulate the combination of prob...

Automatically added tabs for a cube structureThis week, I worked on improving how the RoCo system handles connections. RoCo is designed to allow users to easily fabricate 3D robot designs in a number of ways. Often, this involves breaking up or flattening the geometry, which causes the need for a...
