I am working with the magni robot for my master’s degree thesis in the Politechnic Institute of Engineering in Porto, Portugal.
Lately I am having some problems regarding the power supply of the robot. First the batterys seem to not be working properly. Even though they are charged there is something that is making the robot lose connection with the computer periodically. Then we used a power cord extension to have the robot allways connected to the power supply. This solved the issues of the batterys but after a while the robot motors started having some problems. For example the connection is made with the computer but we cannot receive data from the /odom topic or publish data in the /cmd_vel topic. But this only happens sometimes. The remaining of the time it works. Other thing is a kind of “kick” that the motors do even without the robot having some program running that makes the robot lose connection the the computer.
I hope I am explaning the problem properly. I hope someone can tell me what tests to do to found the issue. Thank you very much.
