reasoning summary现在在答案板上方接近中心。需要在降低时放平,或者可以倾斜放置并缓慢放平。需要根据接触计算物体相对姿态。末端执行器初始抓取 (-.147,-.152,.927),物体中心顶部 (-.148,-.14,.78),底部 .76。相对 R 向下。局部坐标 : [0.147,0.001,0.012],底部中心 [0.167,0.001,.012]。当前 R 向 y 倾斜 .35,世界局部 x [0,.343,-.94],局部 z [0,.94,.343];中心底部现在 p+[0,.0573+.0113,-.157+.004]=[-.004,.0076,.815]。所以底部 .815。答案板 .763 顶部。间隙 .052。目标末端执行器垂直高度 .930,物体底部也许 .763。直接在 (0,-.012,.93) 垂直也许可达,之前高 .973 失败,更低可能仍然?逆运动学可达性可以通过倾斜 .35 辅助。需要测试垂直目标 .937 向前,而当前差 .058,旋转 .35 允许,通过?之前从 .98 到 .973 在远 x 0 处不可达的预检查;新姿态 .933 也许在 q 向下时可达?我们可以尝试 q 向下目标 [0,-.013,.946],可能失败 .015。相反更少倾斜 .17 和末端执行器 ,z .945 然后最终向下 p .934。需要数值局部预检查作为保护,不要慌乱。方向腕部连杆目标测量提供。计算 =1.4(倾斜 .1708)的四元数 .540825,-.455531 等。中间末端执行器 [0,-.037,.948]。物体底部约 .785。放置倾斜 .17 高点长度高度 .01。最终需要放平。

Now above pad near center. Need flatten while lower or can tilt place slowly flatten. Need calculate object pose relative based contact. Eef initial grasp (-.147,-.152,.927), object center top (-.148,-.14,.78), bottom .76. relative with R down. local coordinates R.T delta: [0.147,0.001,0.012], bottom center [0.167,0.001,.012]. current R tilted alpha .35 toward y, world local x [0,.343,-.94], local z [0,.94,.343]; center bottom now p+[0,.0573+.0113,-.157+.004]=[-.004,.0076,.815]. So bottom .815. Pad .763 top. clearance .052. Goal eef vertical height .930 maybe object bottom .763. direct vertical at (0,-.012,.93) maybe reach failed high .973, lower likely still? IK reach can be aided with tilt .35. Need test vertical target .937 forward y-.013 while current difference .058, rotation .35 allowable, passes? precheck from earlier at .98 to .973 unreachable at far x 0; new pose .933 maybe reachable with q down? we can attempt q down with target [0,-.013,.946], might fail .015. Instead fewer tilt .17 and eef y-.034,z .945 then final down p .934. Need numerical local precheck use as guard not flurry. orientation wrist link targets measured provide. Compute q for theta=1.4 (tilt .1708) .540825,-.455531 etc. intermediate eef [0,-.037,.948]. object bottom approx .785. place tilt .17 high point length height .01. need flatten ultimately.
