AlphaBot2 pi posibile hardware bug? #1

Open EmiCoCo19 opened 2 years ago

EmiCoCo19 commented 2 years ago

Hello,

I am using this robot for college project: "maze runner". I am tried to run a python program (on raspberryB+ board) that follows a line but after about 20 seconds it starts to spin like crazy. The right motor wheel blocks, the wheel stops spinning.

Did anybody encountered issues like this? Code attached bellow.

Hi @EmiCoCo19 ! I had exactly the same problem, I attributed it to a machining problem and/or sand getting stuck in the bearings. My solution was to flush the gears of the wheel completely with WD40. Don't hesitate to use too much (without it dripping on the motors), in order to rinse off any dust, but you'll have to wipe off the excess afterwards.

Furthermore, if you are working with a cable that is plugged in and not on a battery, do not neglect the capacity of the cable to make the robot turn on the side of its plug.

Hello,

I want to thank you for your feedback! I sprayed the bearings and now I wait to dry up. I appreciate your promptitude and the detailed response. P.S. If you have more materials regarding this robot I would be grateful if you would share it. :D

Have a nice day!

Hi! There is one piece of information I can share, because it has caused me a lot of trouble, and that is about the robot's power supply. Where I bought it, it was not marked anywhere what kind of batteries were required. It looked like AA batteries, but they didn't work... In fact, you have to use 14500 3.7V batteries Once you know that, there are no more problems ^^
