RoCo Actuation Info Extraction

Chang Liu

Trying to get actuation location from RoCo. Method 1: Write a new code for it Steps: Get motor information from .yaml file (e.g. "fs90r") Refer to dimensions.py for motor geometry information (e.g. "hornlength" etc) Refers to system input for "length", "width" and "height" for "bodylen...

RoCo Geometry Information Extraction

Chang Liu

Here is what we will need to extract from RoCo in order to construct simulation in Webots Updates In the above graph, green boxes have been implemented in RoCo. Now, for each component, we can extract vertices coordinate, facet normal, and coordinate index from RoCo. Example 1: for compone...

RoCo + Webots

Chang Liu

Updates: RoCo can save components separately, in .stl files Coordinate can be saved in .wbt required format in .txt files Facet normal can be saved in .wbt required format in .txt files Details Coordinate points of each component have been saved. Example: RoCo-Saved-Coord (left)...

Tests on the modules of optimization problems

Tsang-Kai Chang

The optimization based SLAM formulate the optimization problem with two kinds of constraints. First, the pre-integrated IMU error establishes the constraints between two spatial states, or two poses. The other one is the reprojection error that links a spatial state and a landmark. In the optimizati...

Consensus on a Quantum Network

Cody Fan

I have been thinking a bit on what consensus on a quantum network means and whether the solution for von Mises-Fisher consensus has any good application towards quantum information theory. There are 4 ways to define Consensus on a quantum network (Mazzarella, et al. 2015): Sigma Expectation Con...

Delta Tolling for Improved Route Planning

Pehuen Moure

Delta-Tolling in Grid-Based Multiagent Systems For a single agent, the problem of warehouse navigation can be considered a simplistic path finding problem over a gridworld environment. With multiple agents existing and acting in this environment, however, the problem of coordinating actions over a...
