Guys I need a little help. I am required to design a robot that will be able to pick up 50 KG worth of load. Application is not specific except that it needs to pick up that much weight. Other things that are presented to me are that robot needs to be 5 DOF robotic arm. And the gear system it will use is Harmonic Gear drive and the motor it will use is servo motors. The problem I need help with is that I am required to find out the torque that the robot would be facing. HOW AM I SUPPOSE TO DO THAT ?? Also dimensions are not provided to me. How am I to just assume them myself ?
