Have you wondered why some robots can run much longer than others, or why UAVs can only hover for a few minutes? The battery pack you choose is certainly important, but there are many additional factors which have a huge influence on the total time your robot operates between charges.
Drive Motors
These things are little complicated for me to understand. Please simplify the details given above if you can and please give more information related to efficiency.
I want to build a robot similar to the mars curiosity rover.
I am using the arduino board from an mbot for the programming part.
I am planning to use 2 12V DC motors that have 30rpm, rated current of 0.1A and rated torque of 12kgcm.
I am planning to use 3/4 80mm silicone wheels.
Should I use a LiPo Pack of 1300mAh 4s 40c or a 9g Continuous Rotation Micro Servo
I have seen your Drive Motor Sizing Tool.
But I do not know how to deterrmine the efficiency.
Based on the parts that I have, I am not sure I underrstand the output on the tool.
Can you please let me know if these parts are compatible with each other in building the robot.
Please advice.
@Nisha We see you have many questions – we propose you create a new topic on the RobotShop Forum with all of your questions and what you would like to create and we would be happy to answer there.
@cbenson can you help me how to measure operation time of our 6-wheeled wall climbing robot driven by D.C. motors and propellers powered by 4 BLDC motors.We are using YPG 2600 mAH 3s 11.5V 35C.By the way our design is dual coaxial for our design…Is it quantitatively measured and how?Thanks in advance @cbenson
@Lyxcier Measure? Not quite… I’d have to be there 
Can help you work on the theory, but you’ll need quite a few estimations. Can you create a new forum thread and post the details of the design (how many drive motors, the details of each motor etc.) and what you envision to be its “wall climbing” capabilities?
