Key Limitation Lack of tactile feedback Inflexibility in procedures Inability to fully replace humans
Cost Issue High upfront and maintenance Similar cost barriers High costs impede widespread use

From a technical perspective, the precision of medical robots can be expressed through error minimization formulas. For instance, in both surgery and dentistry, the goal is to minimize a loss function: $$ L = \sum_{i=1}^{n} (y_i – \hat{y}_i)^2 $$ where y_i is the target position and ŷ_i is the robot’s achieved position. The lack of feedback remains a critical hurdle; integrating force sensors could improve this, but it adds complexity. The high cost of medical robots can be analyzed using cost-benefit ratios: $$ R = \frac{B}{C} $$ where R is the ratio, B represents benefits like reduced recovery time, and C is the total cost. Currently, R is often low due to high C, limiting accessibility. These insights highlight the need for innovation to address shared weaknesses in medical robot systems.
