Dear Robotshop technical experts,
This is my first time building anything... so I'm sorry for the excessive questions!
I am currently building a robot for a design project in university. I am currently using a Zheng DC gearbox motor (12V, 50RPM), and I would like to mount RB-Ban-94 (Banebot 2-7/8") wheels on them using a suitable hex hub.
The problem is that the shaft on my motor is about 4mm in diameter and round except for one slightly flat side (looks somewhat like a D in shape) and only about 1.1 cm in length, so I am afraid that the hex hub will not fit onto the motor shaft.
Do you have any products/advice that would help?
Also, I would like to mount to non-driven wheels to a 4mm diameter round shaft and secure them in place, as well as securing the shaft to the chassis of my robot.
Do you know how I could accomplish this?
Thank you so much for your help!
