PHASE 2: ASSEMBLE ========================================================= Use the Phase 1 parts only. Do not remodel them. Orient the whole assembly with origin at pivot O2, X horizontal, Y vertical (up), the ceiling at Y = 0. Step A: Position the fixed parts. Wall_Bracket in the XY plane at Z = -12 (mid-plane), with hole O2 at (0, 0) and hole O4 at (0, -312.5). Step B: Stack the links along Z (mid-plane of each link): Link_O4A Z = 0 | Link_CD Z = 12 | Link_O2C Z = 24 | Link_BC Z = 36 | Coupler_AB_Door bar Z = 48 (door panel on its +Z side). Links are 8 mm thick, so there is a 4 mm gap between adjacent layers. Step C: Place each link in the XY plane so its holes land on these points (pose: input angle about 51 deg, door angle about 174 deg): O2 (0, 0) O4 (0, -312.5) A (186.6, -82.1) D (62.9, -234.8) C (-133.0, -181.5) B (-77.6, -54.3) Door tip at about (-410, -19). Link_O4A: O4 to A. Link_O2C: O2 to C. Link_CD: C to D. Link_BC: B to C. Coupler_AB_Door: A to B, the bar and door continuing past B in the same direction. Step D: Insert the 7 pins (axis parallel to Z) with spacers: O4: through the bracket and Link_O4A. O2: through the bracket, the 10 mm OD sleeve (36 mm), and Link_O2C. D: Link_O4A and Link_CD. C: Link_CD, Link_O2C, Link_BC (three adjacent layers). B: Link_BC and Coupler bar. A: Link_O4A, a 40 mm sleeve, and the Coupler bar. Pin heads on the -Z side where possible, E-clip grooves free of links. Step E: Mate definitions (for later animation). Define 7 revolute joints on the pin axes. One degree of freedom. Driver: rotation of Link_O4A about O4, from -90 deg (closed) to +90 deg (open). Keep the same assembly branch (C to the left and below line O2-D, B to the left and above line A-C). Step F: Validation poses (check the joint points, do not keep these poses). Closed (input -90 deg, door vertical): A (0,-609.0), D (0,-412.5), C (-57.2,-217.6), B (1.3,-343.4), door tip (2.8,-9.0). Open (input +90 deg, door under ceiling): A (0,-16.0), D (0,-212.5), C (-184.8,-128.3), B (-265.6,-15.6), door tip (-600,-15). Report any interference between bodies in all three poses. DELIVERABLES 1. Eight separate part files (with 7 pins and the sleeves as copies). 2. One assembly in the 51 degree pose, all bodies named (Link_O4A, Link_O2C, Link_CD, Link_BC, Coupler_AB_Door, Wall_Bracket, Pin_O2, Pin_O4, Pin_A, Pin_B, Pin_C, Pin_D) and coloured as above.
