To reassemble the MiPosaur, place the two halves of the gearbox together, and secure it with the screws. Place the gearbox back in the leg and secure the wire with the wire holder. Attach the screw and route the wire through the leg in order to reattach the halves. Resecure the leg with the screws.

Reattach the leg to the body and secure it with the screws, routing the wires through the body. Reconnect the connector to its socket and secure the motherboard and on/off board down in place with their corresponding screws. Close the two halves of the body and secure with the screws. Place the blue tabs back on the MiPosaur.

Place the battery compartment into the MiPosaur and secure with the attached screws. Now, turn on the MiPosaur and test if the MiPosaur will function correctly. If not, you can compare by doing this guide with the other leg. If you notice that the malfunctional leg is missing pieces or has damaged ones, you can replace these pieces.

In addition, you could purchase a new gearbox and this should get it working correctly again after doing the reassembly using a new gearbox.
