Shipping

On November  14th, we shipped our boat for the competition which will be held a month later. It was 8 o’clock in the morning when we received a newly made crate for our boat, WAM-V. Then we add some sponges inside so that it wouldn’t damage the boat when being transported. And we packed the boat and […]

Experiment 2

October 7th, we carried out experiments. That day was a perfect day for the experiments. First, we floated the hull that is showed below on a pool to conduct a test on the hardware. This is a picture of we were observing how this hull move on the pool. To check degree of sinking, a member […]

Experiment 1

We planned to do our experiment on September 30th weekend if everything would go well. We prepared for the experiment the day before. However, the experiment was canceled due to typhoon, and we couldn’t do it. The hardware group assembled the propelling mechanism and created the simplest circuit to move the hull. People who were […]

Run YOLO in opencv node

Yesterday, we built opencv-3.3.1 and contrib for Jetson TX2. After opencv-3.3, opencv contains yolo deep neural network. So, we make a simple ROS node for object detection by using tiny yolo and try it!! The code is here. This node can run only 2Hz. This is 5 times as slow as using using darknet in […]

Build ros-kinetic-opencv3 package for Jetson TX2

ros-kinetic-opencv3 package is very useful for ROS users, but this package is not supported cuda. So, we built ros-kinetic-opencv3 packages with cuda modules in Jetson TX2. Compiled binary is here. Usage is below. 1.install dependencies 2.remove ros-kinetic-opencv3 3.install dpkg We built this .deb file in this way.(<a href=”https://qiita.com/kendemu/items/a805b0b9828b6f6031db”>reference</a>) 1.get ros-kinetic-opencv3 source from apt-get 2.remove source files […]

Run darknet in Jetson TX2

In order to use Jetson TX2 and Deep Learning in this competition, I tried to run darknet in Jetson TX2 and tested Jetson TX2 throughput. In this post, I used Tiny-Yolo deep neural network in Jetson TX2. This is the result of object recognition. Tiny yolo structure is here. dog.jpg eagle.jpg giraffe.jpg person.jpg scream.jpg Prediction […]

Compile tensorflow on Jetson TX2

We use tensorflow in order to use deep learning algorithms such as Faster-RCNN, Yolo, VoxelChain. Compiled .whl file is here. If you want to install tensorflow into Jetson TX2, you should follow these instructions. 1. download jetson_tensorflow.zip 2. unzip jetson_tensorflow.zip 3. cd jetson_tensorflow 4. sh install.sh We checked this .whl file by using this python […]

Object Detection System

We build object recognition system using point cloud data. This node are composed of ros_ship_recognition package. The object_recognition_node detect objects by using SHOT features. We conducted a presentation about this node in ROS Japan user group meeting in Kansai. 3D Object Detection using PCL (Point Cloud Library) from masaya kataoka Demonstration movie is here.

WAM-V Simulator

We are building gazebo/ROS simulation package for WAM-V. Our simulator has a such characteristics. 1. buoyancy simulation We calculate buoyancy from archimedes’ principle and simulate it! 2. driving force simulation Ship’s driving force are calculated from it’s speed and propeller rotational speed. We develop driving force controller and control ship’s driving force. 3. Visualization We made […]
