AndyBoard - April 2024 - Lab 1 - A Basic Robot - Part 6: Steps 91 thru 118

Follow the steps below to install the bump sensors, the remaining superstructure, and the cage that will contain and protect the AndyBoard on-board computer.

Step	Procedure	Picture
91	Locate one left hand bump sensor , one right hand bump sensor , one 1 x 8 beam (p/n 3702) , one 1 x 10 plate (p/n 4477) , and one 1 x 8 plate (p/n 3460)
92	Snap the bump sensors and the 1 x 8 beam into place as shown, and then snap the 1 x 10 plate and the 1 x 8 plate into place.
93	Locate two 1 x 12 (p/n 3895) beams
94	Snap the two 1 x 12 beams into the locations shown
95	Locate one 1 x 12 beam (p/n 3895) , two 1 x 8 plates (p/n 3460) , and two 1 x 16 beams (p/n 3703)
96	Snap the 1 x 12 beam into place as shown. Then on snap the two 1 x 8 plates and then the two 1 x 16 beams
97	Locate two 1 x 10 beams (p/n 2730) and four black friction pegs (p/n 2780)
98	Snap the black friction pegs and the 1 x 10 beams into place as shown. Note how the beams run perpendicular to the rest of the beams. The effect of this is to lock the other beams into place, making the robot robust while keeping it light
99	Locate two 1 x 16 beams (p/n 3703) and two 4 x 4 plates (p/n 3031)
100	Snap the two 1 x 16 beams into place as shown and then snap the two 4 x 4 plates onto them. Note that all the wires from the sensors and motors rise up in front of both of these 1 x 16 beams. Also note that the wires from the motors and the shaft encoder sensors pass under both these beams
101	Locate one 1 x 16 beam (p/n 3703) and two 1 x 6 beams (p/n 3894)
102	Snap the 1 x 16 beam onto the back decking as shown and then snap the two 1 x 6 beams on from below
103	Locate one 1 x 4 beam (p/n 3701) , one 1 x 12 beam (p/n 3895) , and one 1 x 2 beam (p/n 3700)
104	Snap the 1 x 4 beam on at the junction of the the 1 x 12 and 1 x 6 beams as shown. Then snap the 1 x 12 and the 1 x 2 beams into place
105	Locate one 1 x 4 beam (p/n 3701) , one 1 x 12 beam (p/n 3895) , and one 1 x 2 beam (p/n 3700)
106	Snap the 1 x 4 beam on at the junction of the the 1 x 12 and 1 x 6 beams as shown. Then snap the 1 x 12 and the 1 x 2 beams into place
107	Locate one 1 x 16 beam (p/n 3703) , one 1 x 12 beam (p/n 3895) , and two black friction pegs (p/n 2780)
108	Snap the 1 x 16 beam onto the 1 x 2 beams installed in steps 104 and 106, as shown. Then insert the black friction pegs into the holes at the ends of the 1 x 12 beam and snap the beam into place, vertically, as shown. This is another example of using beams that are perpendicular to make the structure stronger and more rigid
109	Locate two 1 x 12 beams (p/n 3895) , four 1 x 2 plates (p/n 3023) , and two 1 x 2 beams (p/n 3700)
110	Snap the two 1 x 2 beams into place in a tower as shown. Snap a 1 x 2 plate onto the top of the 1 x 2 tower. Snap another 1 x 2 onto the 1 x 16 beam at the back of the robot. Note that this plate is perpendicular to the other 1 x 2 plate. Snap a 1 x 12 beam onto the top of the two 1 x 2 plates just added. Snap two more 1 x 2 plates onto the top ends of the 1 x 12 beam. Finally, snap a 1 x 12 beam onto the two 1 x 2 plates
111	Locate two 1 x 10 beams (p/n 2730) and four black friction pegs (p/n 2780)
112	Insert the black friction pegs into the holes at the ends of each 1 x 10 beam and snap the beams into place, vertically, as shown.
113	Locate two 1 x 12 beams (p/n 3895) , four 1 x 2 plates (p/n 3023) , and two 1 x 2 beams (p/n 3700)
114	Snap the two 1 x 2 beams into place in a tower as shown. Snap a 1 x 2 plate onto the top of the 1 x 2 tower. Snap another 1 x 2 onto the 1 x 16 beam at the back of the robot. Note that this plate is perpendicular to the other 1 x 2 plate. Snap a 1 x 12 beam onto the top of the two 1 x 2 plates just added. Snap two more 1 x 2 plates onto the top ends of the 1 x 12 beam. Finally, snap a 1 x 12 beam onto the two 1 x 2 plates
115	Locate two 1 x 10 beams (p/n 2730) and four black friction pegs (p/n 2780)
116	Insert the black friction pegs into the holes at the ends of each 1 x 10 beam and snap the beams into place, vertically, as shown.
117	Locate one 12 unit long axel (p/n 3708) , one 6 unit long axel (p/n 3706) , one coupler (p/n 6538) , and two collars (p/n 3713)
118	Insert the axels through the top 1 x 12 side beams as shown and use the coupler to join them. Slide the collars onto the ends of the axels as shown.

That completes installation of the bump sensors and construction of the remaining superstructure and the cage that will contain and protect the AndyBoard on-board computer.
