I have removed "Requesting assistance" as it clearly does not apply. What robot are you inquiring about? What product? Please provide information or this post will be removed.

As @DJ mentioned we need way more info... What wheels and what robot?... If you are talking about continuous rotating servos they rotate at about 60rpm because of internal gearing... If you want 280 rpm you will either have to re-gear them (which will be almost impossible) or buy a gear motor that does 280rpm.... Just curious are you new to robotics or a young kid or?
