Vital efforts are been made to study a Remote Controlled Compact Pneumatic Actuator. Scotch-yoke is an important component whose function is to convert rotary motion to linear motion. The scotch-yoke is subjected to compressive forces and was found to be the component failing consistently in the actuator. Hence it was found necessary to modify the existing design. This paper attempts to perform a design optimization of the scotch-yoke used in the RCC pneumatic actuator using linear static analysis. The results are compared and changes are suggested. The key parameters of interest of deflections & stress distributions in the scotch yoke. The baseline model had deflection of 4.234 mm, 1.9783 mm & 0.0125 mm in the x, y & z directions respectively while the deflections in the optimized model had deflection of 3.943 mm, 2.296mm & 0.006007 mm in the x, y & z directions respectively. The normal stresses in the baseline model 2191 N/mm2, 1439 N/mm2& 681.063 N/mm2 in the x, y & z directions respectively, whereas the normal stresses in the optimized model were 1369 N/mm2, 1392 N/mm2& 521.707 N/mm2 in the x, y & z directions respectively. The von Mises stress in the baseline model was 3643N/mm2 and in the optimized model is 2706 N/mm2.
