Elderly care robots need to meet three core requirements

Elderly care robots need to meet three core requirements: safety (no damage from collisions), battery life (≥12 hours), and flexibility (precise load-bearing/assisted movements). For every 1kg increase in the weight of the whole machine, the joint load and energy consumption will increase several times. Lightweighting can directly reduce energy consumption by 10%-22% and improve motion response by 5%-25%, ensuring the safety of the elderly.
