Basic tools are used to assemble the Rover and Multi-Axis camera assembly. These tools include a small Philips screwdriver (No.1 or pocket screwdriver), needle nose pliers, and Allen wrenches.

After all of the 3D printed components have been made and ready for assembly, it may be necessary to “clean” the 3mm holes using a 3mm or 1/8” drill to provide easy assembly.

The motor side plates are attached to the Rover platform using two 1/2” 4-40 Philips head machine screws and nuts. It is advisable to have a small bottle of nail polish or model paint the serve as a “thread locking” material.

Orient the motor side plate with the mounting flange toward the center of the Rover platform.

Tighten the nuts securely but do not over-tighten the machine screws as it may crush the printed parts.

Select Screws and Nuts

Align Parts

Note which side the mounting flange is oriented. Assemble this motor side plate with the mounting flange toward the center of the Rover platform.

Tighten the nuts securely

Complete this assembly

Attach gear motor drives to Rover side plate using 4-40 X 1-1/4” machine screws and nuts. The motors should be mounted with the wire-side out. Place nuts on the inside of the motor side plates.

Attach the last pair of motor units to the other side plate. Note that the motors are wired together. Each pair of motors are connected together to turn in the same direction. When the motors are properly connected, all four motors will turn in the same direction in a forward or reverse mode.

Select the crews, washers and nuts, insert the power switch from the bottom of the board, add screw with washer from the top of the board and tighten the screw using a nut.

Slide the battery shelf under the platform (between the two motor side plates)

The shafts on the Rover motor gear boxes have “flats” on the shaft. The flats on the shaft must be aligned correctly so that the wheels will slip on the shafts snugly. Hold the yellow motor gear box securely when attaching the wheel.

Attach the remaining three wheels. Hold the driver motor securely when attaching the drive motors as the motor side support brackets may break.

Attach the Arduino UNO controller board using three 4-40 X 1/2” socket head machine screws with plastic spacers and nuts.

Do not over-tighten screws. The programming USB “B” socket must face outward (away) from the Rover platform.

Attach the motor shield to the Arduino UNO board. Use care in aligning the shield orientation and connector pins.

The screw terminals are oriented toward the silver USB connector on the UNO. The shield pins will not “seat” all the way into the UNO connector sockets.

install wires at DC Motor Shield board

Install the ground wire (black) from battery to the Ground Terminal (Colored in Black)

Connect the red wire to the power switch and Install wire from power switch to DC Motor Shield Board, make sure your swtich set the "Off"
