121 Jan 201931 Jan 2019jianminzUAV battery charger smokeUAV battery charger left smoke when plug in the batteryContact Intel and got a new part shippedWorking battery charger
24 Feb 20195 Feb 2019yunfeiscannot connect LLP and on board computer Cannot read sensor via serial communication between LLP and onboard Computerneed to communicate with HLP instead, need to first flash program in./
35 Feb 20197 Feb 2019yunfeiscannot flash program to HLPopen-ocd cannot connect the on-board computer using JTAGopen-ocd does not support out-dated syntax. Need to rewrite the config filecan now flash program to HAP
47 Feb 201914 Feb 2019jianminzchecksum error when running ros package on atom boardshow error msg "checksum error for packet 14 ,resyncing "Update the Baud rate by 8 timescan now read IMU data, and GPS Data
514 Feb 201929 Mar 2019yunfeis, jianminzwhen launching fcu.launch, battery cannot be correctly readshow error msg " battery critical low"This is due to serial did not read the battery voltage when initializing. This does not affect the performanceNothing
616 Feb 201918 Feb 2019ningwangGraphic simulation was not connected with the main program.Changes in code was not reflected in simulation.Failed to configure Rviz and Gazebo ports in code Rviz and Gazebo are now able to reflect the correct simulation progress.
718 Feb 201918 Feb 2019ningwangOnly two maps shown in the simulation, where should have been 3.After adding an extra map to show variance changes, the ground truth map was able to show.Changed the coordinates for drawing variance map.Now three maps all show correctly.
823 Mar 20199 Sept 2019jianminzOne UAV crashed due to a different operation mode and the serial remotely turned off the motor while UAV hovering at around 10 mcamera and Lidar hold for UAV 1 is broken.We switched to use UAV 2 for SVD and request spare parts from Intel. The spared parts arrived in summer, UAV 1 reparation finished in Sept 2019UAV 1 now have solid camera and lidar mount
93 Apr 201910 Sept 2019yangzha4, yunfeisJackal localization fusing GPS has a large drift.Jackal localization with IMU and Odometry is working. When RTK GPS is integrated. Jackal appears to move to one direction without stop. Use dual EKF. One fusing IMU, Odometry, the other fusing IMU, odometry and GPSUGV can now do stable GPS navigation.
108 Apr 20195 Nov 2019jianminz, ningwang, yunfeis, yangzha4Clearpath Base Station has a very low speed that cannot handle UAV UGV working at the same timeClearpath Base Station has a very low speed that cannot handle UAV UGV working at the same time1. shut down unnecessary nodes.
2. use the new router as a wifi booster		UGV and UAV can now working withing the same network.
1128 Oct 20195 Nov 2019jianminz, ningwang, yunfeisJackal cannot connect to the new routerAfter connecting to the new router, Jackal cannot be found connected in the network and cannot be pingedUse new router as a wifi booster. Seeking technical support from clearpathJackal still connect to the old network, but the connection speed now increases.
1227 Oct 201910 Nov 2019yangzha4, ningwangUAV temperature measurement is very close to the ambient temperatureTo be safe, UAV will collect data at 1.5m, but it does not show great temperature difference from the ambient.Perform two tests: Functional test using UAV UGV to show valid pipeline, and accuracy test of UGV collecting temperature solo to show temperature distributiononly changed testing procedure
1318 Nov 201920 Nov 2019yangzha4GP model not updating due to wrong hyperparametersGenerate uniformly distributed temperature modelRe-tune the parameters and verified the GP model in simulation and rosbagGP parameters
1418 Nov 201921 Nov 2019yangzha4, ningeangGP model visualization not correct with various scale and color codeThe visualization is not updated and the color code used is not staticupdate the visualization channel. use fixed color code for visualizationvisualization code in sampling core
