Design of the Base of the Robot

The architecture of the robot sits on a line tracker robot type – base . The structure is built between two plates (diameter : 140 mm) braced by motor plates which support DC  motors . The motors receive the wheels which are fixed on the rotor arms. Two stabilizing ballcasters help keep the balance of the robot .
The robot may be fitted with different units : tracking device, obstacles sensors, robotic arm, camera ...
The base also receives the electronic and the energy parts.

Four parts are machined using differents process : EDM (Electrical Discharge Machining), milling, turning.

Notes :
With TopSolid, in order to know the mass properties of a particular part, proceed as follows : select Attributes context , activate the fonction Design analysis , choose : Physical Informations = Yes and click on the part to analyse.
Depending of the energy solution, we have to add accumulators mass (rather important mass).
