github.comA fast and efficient type assistant for Python, including tensor shape inference - RightTyper/RightTyper
Linked is Python RIghtTyper which sounds great... if it works. It will analyze the type hints in your python (if any) and offers to gerentate them for you. Something like that. Many ways in which that might not go right but I read a very positive overview of it!

How to Calculate the Motor Torque for a Mobile Robot
wiki.dfrobot.comThis guide outlines how to calculate power parameters for a mobile robot and select an appropriate power system. We cover frictional and acceleration forces, wheel type, and motor parameters to design a direct-drive system with a brushless motor. With the rated voltage, speed, and torque of the motor, we calculate the required power and minimum battery capacity to power the robot successfully. This discussion is a valuable resource for designing or selecting a power system for an indoor, service-oriented mobile robot capable of carrying a payload of 20 kg and achieving a speed of 1.
Linked is an article explaining how to calculate torque. But why? When choosing a motor for a robot, you need to calculate the torque required, which in turn depends on the weight of the robot, the diameter of the wheels, and other parameters.

Kinda cool. Linked is a simple tool which formats a cv in one of several styles. But the trick is that the input is a yaml file which contains all the content as a structured text file that you can edit with vscode and version track with GitHub. Nice!
