Logics Project -- RoCo + Webots

Chang Liu

Goal 1: Get RoCo-designed robots to work well in Webots Problems: RoCo generated .stl file is for presentation, the parts are considered as one solid body, which means there will be no rotational/translational parts simulated in Webots. How to get RoCo generate files that can differentiate t...

Logics Project -- RoCo + Webots

Chang Liu

Pehuen and I are working on computational design and evaluation of robots. This project will take realistic manufacturable robotic designs from RoCo and evaluate them in Webots. Flowchart: here is a flow chart that we came up Tasks: the parts that are marked in red are what is missing in thi...

FORAY - Testing control using camera

Zhaoliang Zheng

In order to verify the use of camera automation control, I set up a camera on a quadrotor. I will use this as testbed to understand and test some algorithm and data on it. Right now, I can use this camera to proceed Wifi remote control:

EM SLAM on EuRoC dataset

Tsang-Kai Chang

We are now able to demonstrate that the performances of EM-based SLAM algorithms are comparable to that of optimization-based. However, it is not easy to observe that same thing in the real-world dataset. simulation result The first challenge is whether to use IMU data or to only use the output...

[paper review] Evolution of Kalman Filter for input estimation

Zida Wu

Those slides are presenting the evolution of input estimation based on Kalman Filter. I picked up 14 papers as the representatives of those evolution. Next week I would implement the 2d Multi-model and test to see how effective the new MM algorithm perform better than the native one.

LOGICS project initialization

Chang Liu

LOGICS Project Pehuen and I have been working on building robotic cars & boats from RoCo design system and evaluate their performance in WeBots simulation system. 1. We want to build robots in WeBots directly. Here are some robots that have been built: (1.1) A four-wheeled car Design code:...

ROS ready-to-go Virtual Machine system

Zhaoliang Zheng

Recently, I created a Linux VM system that pre-installed all the software for running a ROS. For beginners, this ROS ready-to-go system will be super easy to use. To use this virtual machine, you need to install VMware first. Go the link1 link2 to download vmware if you don't have one. Th...

Computational Design of Planar 3D Structures -- Buckling -- Intermedium Results

Chang Liu

Part 1: Correcting Y Direction Deflection Y direction deflection correction Following last week's blog post, I modified our design tool. The new results show a better match for y-direction deflection. Here are some of the results: 1. FCFC, clamped on longer edges, forces on shorter edges...

Scalling Lifelong Multi-agent Path Planning via Local Field of View

Pehuen Moure

Scaling multi-agent solutions is difficult due to the exponentional growth in state space. To this end we are implementing a local field of view for each agent. Each agents local goal will be determined by running A* over the entire space and finding the last position in the field of view. This fo...
