Originally, the chassis of the Roktrack was made of aluminum composite plate, but it was not strong enough, and the motor mounting points were sometimes tilted. Above all, it was very difficult to drill many holes by hand.

Then we received an offer from PCBWay. It was my first time to use a sheet metal service, but all I had to do was send them a dxf file and they sent me a precisely machined 2mm aluminum sheet.

Unlike manual machining, the motors and other components were accurately installed in one shot, and the parts did not deflect or tilt under load. Compared to the aluminum composite sheets we have used in the past, the reliability has increased overwhelmingly.

My first experience with sheet metal in my life ended in success. We plan to increase production in the future and are considering using sheet metal services instead of hand fabrication.
