Inspection robots with flexible wheel/motor positioning

An inspection robot, the robot comprising:

• a housing comprising a first connector positioned on a first side of the housing, and a second connector positioned on a second side of the housing;
• a first drive module operatively coupled to the first connector, the first drive module comprising at least one first wheel and a first motor
• a second drive module operatively coupled to the second connector, the second drive module comprising at least one second wheel and a second motor;
• and
• at least one electronic board and at least one removeable interface plate, wherein at least one of the first drive module or the second drive module is electrically coupled to the at least one electronic board via the at least one removeable interface plate,
• wherein:
• the first motor is in line with the at least one first wheel and is directly coupled to the at least one first wheel such that a rotation of the first motor rotates an axel or a hub of the at least one first wheel;
• and
• the at least one first wheel is interposed between the first connector and the first motor such that the first motor is positioned outside the first wheel relative to a center of the housing.
