The following is the Chassis Frame and Drive Module Assembly for the Autonomous Mobile Robot (AMR). The total weight of the AMR is 150 kg, We want the platform to have a variable height adjustment. The platform height is controlled by the torque applied to the timing pulley. Find the torque "M" to control the platform height of 150 kg. Consider an M12 screw with a friction factor of f=0.2. 496.00 axis (1) right-hand thread 586.00 Torque (M left-hand thread 515.00
