Abstract

Industrial robots are capable of moving at high
speed. Each time they come into contact with their environment,
e.g. to pick up an object, they decelerate to a near standstill. A
solution involving a compliant pneumatic gripper and adapted
trajectory plan is presented to initiate contact at a higher speed
while remaining within hardware limits. By adding overload
clutches in either the robot arm or gripper, tolerance to errors
is provided. The key parameters such as gripper compliance
and maximum allowed initial impact velocity are identified.
Results show that by properly optimizing these parameters,
robot picking of rigid objects can be accelerated. The complete
high-speed picking solution is experimentally verified. A time
reduction of 16% was obtained when making contact at 0.65
m/s.
