Bending adhesion compression Tension PSA

PSA toybot Number of DOF- 10 Hip joint servo - 6 Main thrusting - 2 PSA –peeling – 2 Actuation scheme – Servo driven push-pull cable Gait type – alternating tripod Weight - 200g

2 DOF legs 2DOF per leg Front leg (pull -> pull)Rear leg (pull -> push) -Key point : Flexible cable without sheath can not push hard Main power transmission - pulling

Servo motor PSA push-pull cable Main thrusting DOF push-pull cable

PSA Non-sticky pad Engagement Disengagement Push-pull cable

Problems.. Actuator.. Foot placement scheme Leg position

Leg actuation Actuator - Is servo motor the best selection? - What is muscle-like actuator? - How do we control compliance in power transmission path ?

Sensors. Do we need sensor? –Body pitching, rolling.. –Foot attach detection -Optic sensor? Gyro? -What type of CPU do we need ?(Virgilio) ?

Leg interaction -Do we need force sensor on foot? -How do we accommodate difference among legs stroke? - How do we control Ground reaction force to maximize stability ?

Leg position Alternating tripod?

Insect…

Questions.. What weight range is reasonable for Climbing robot? What size ? How do we optimize weight/ power ?
