Manual Robotics day1

Robotics basics

Introduction to robotics: competition robots, industrial robots, domestic robots, space robots, robot chassis, PMDC motor, Differential drive, Steered wheel drive, omini wheel, double differential, Gear and transmission, material to be used for robots

Use of tools

Using multi-meter for testing continuity and components. How to safely handle batteries.

Components reverse engineering:

Open up  100 rpm  motor and observe RPM after each gear division

Compare 100 rpm gear structure with 7 rpm gear structure write differences you observed.

Observe torque by pressing fingers against the rotation of the shaft, check after powering it up
