Hi, I have 2 wheeled drive robot here is the spec

total Mass of robot = 20 kg

Wheel radius = 0.05 m

Desired velocity= 1 m/s

Desired acceleration =2m/s

From torque calculation = F. R = ma.Radius = 20 x 2 x 0.05 = 2 Nm

should it be divided by 2 so 1 Nm per motor ?

In other words I should get the motor that has 1 Nm

Q2. How inaccurate this calculation in sizing the motor?If I use RMF calculation I could not derived the torque, I should need to find the motor 1st and get the input torque then put inside the calculator, Where my difficulties the vendor is asking me what is the torque you need, So i need the calculated torque, Please give me an advice ya

Q3 In the calculator on excel, it said " if you have twice the motors, then they just need half the output ", should i divide the RMF by 2 ?
