Objective　To verify the effects of microlecture based on robot carrier on standardized residency training of orthopedics. Methods　Sixty orthopedic residents from our hospital were divided into two groups according to different training methods. One was control group (n = 30)

receiving regular training methods

and the other one was experimental group (n = 30)

receiving additional microlecture based on robot carrier besides regular training methods. The teaching effects of the two groups were compared after the training in orthopedics department. SPSS 20.0 was used for t test. Results　There was no significant difference between the experimental group and the control group in theoretical tests results [(88.63±10.24) vs. (87.85±9.62)

P > 0.05]. The operation test scores in experimental group (92.12±7.52) were significantly better than that in control group (85.35±8.12)

with statistical significance (P < 0.05). The satisfaction scores for teaching in experimental group (90.00%) was significantly higher than that in control group (70.00%) (P < 0.05). Conclusion　Microlecture based on robot carrier could enhance abilities of skills operation for orthopedic residents during the standardized residency training and improve their satisfaction for the teaching effect.
