We decided to add the wheels into the trolley.

This video shows how we prepared the wheels.

We also had to cut the protruding screws that hold the wheel to the base as these screws were blocking the wheels’ proper rotation.

Lastly, this video shows the wheels in action! They are extremely heavy duty as these 6 wheels can carry a combined weight of up to 8 tonnes! Those are some pretty heavy duty wheels.

Moving on, We also 3d design and printed housing for arduino + two dc motor controllers and wires. The two DC Motor controllers will be on the left, and the Arduino board will be on the right.

Before we attach the components onto this 3d-printed base, we decided to wire all actuators with dc motor controllers + arduino, modified arduino code (to accommodate all 3 actuator systems + the shift from Ardunio Mega to Arduino Due) and tested the system (success!).

Lastly, we soldered many wires, including the variable resistor to wires and we are currently testing it.
