The story is that this is on a robot that I took home with me to do some-last minute programming. When it got to my house, I discovered that the mechanical and d electrical teams had not done any testing at all
, and the robot had several malfunctions, including this sprocket that was not properly fastened onto the gearbox thingy. However, the problem was, being at my house and not our shop,I lacked the proper tool to attach it. So this is our interim solution:hot glue.
