We visited the lab again today, on Monday 31st August, 2020.
When we arrived, we were ready to test the two digital cables we each made in the last two visits. We connected controller to the computer to tune the motors by setting various parameters such as the offset of the motor, the maximum current, maximum revolution, enable/disable, etc.
Even though we conducted continuity tests with a voltmeter to ensure the cable was working, we initially had trouble getting the motor to work. It turned out there was a defect in one of the motors which prevented it from working, so we'll need to contact Maxon Motors to fix it for us. When we tried both of our controllers with the other two motors, it worked perfectly.
We soldered the analogue cable we stripped on our last visit. We all joked that "when soldering, you need three hands." You need to hold the solder, the soldering iron and the object to solder.
We attached the analogue cables we soldered today and the digital cables from the controller to the Ni-board
Now that all the cables are connected, we just have to tidy up all the cables, replace the broken motor and then we can start coding the hand!
