Global robot end effector market is expected to grow from USD 2.3 billion in 2023 to USD 4.3 billion by 2028, registering a CAGR of 13.5%.
Driver: Increasing demand for modular end effectors by various industries.
Due to the fast-changing nature of industries, the demand for modular end effectors is increasing. This scenario is observed in the consumer goods industry, specifically packaging, where the shape, size, surface, or weight of the packaging is constantly changing. This shortens the life cycle of an end effector to 1 to 2 years and thereby increases the cost of replacement for the company. Modular end effectors have the capability to accommodate and handle a large variety of objects as required. A modular vacuum bar from Schmalz (Germany) can perfectly seal and lift objects regardless of their size; Zimmer Group (Germany) and Schunk (Germany) introduced a modular gripping system – MATCH with an unlimited range of uses from production and assembly to warehouse logistics, shipping, and even laboratory automation. This modularity ensures that the grippers do not have to be changed from time to time, thereby reducing the cost of redesigning and downtime associated with its change and replacement. Modularity can be seen in other forms as well, where the end effector components such as mounts and accessories can be quickly swapped without drilling or welding. Destaco (US).

Restraint: High cost of deployment, especially for SMEs.
Small and medium-sized enterprises (SMEs) differ from large-scale industries such as automotive or electronics manufacturing in various ways. SMEs typically have a low threshold for capital expenditure, a low-risk appetite, and limited time to generate returns on their investment. Additionally, their applications are often specific and on a case-by-case basis. For instance, Saint-Gobain, a glass manufacturing company in France, required automation of its glass polishing process that was previously carried out manually. Robotiq successfully automated the process by programming its torque sensor to replicate the hand movements and pressure applied by a human. Unlike large industries, many SMEs have not built their infrastructure around deploying robots, and must often integrate them into their existing floor space at a later stage. Since the growth of end effector in SME applications is slowly outpacing the growth in the automotive sector, companies have started taking certain initiatives, such as Universal Robots (Denmark) and Robotiq (Canada), are now making use of advertising campaigns showcasing different use-cases and estimating payback period. Zimmer Group (Germany) has set up a division known as the Know-How Factory to solve challenging implementations of end effector and robot systems, reducing the hassle of integration for their client. However, industrial robots and automation still remain a cost-prohibitive investment for most SMEs.
Opportunity: Advancement in robotics has surged the demand for soft grippers.
Advances in soft robotics, coupled with the increasing need to handle delicate items, have enabled rapid progress in soft grippers. Unlike traditional grippers that are made of rigid materials, these end effectors are fabricated from soft and flexible components. Earlier, most end effectors were able to only manipulate objects of fixed size and shape. However, industry requirements are slowly shifting toward the use of components that can grasp and manipulate a large variety of objects. Due to the material softness of the gripper arms, they can be used for sensitive applications such as in the food & beverage or glass manufacturing industries that can handle objects without damaging them. Fruits or vegetables have varying sizes, making soft grippers ideal due to their consistent clamping force irrespective of slight differences in size and shape. Soft grippers are mainly adopted by the food & beverage industry, one of the fastest-growing clients for soft grippers. Hence, the high penetration rate of automation in the food & beverage industry is expected to stimulate the adoption of soft grippers in the next 4 to 5 years.
Challenge: Interoperability and integration issues related to end effectors with existing facilities.
Interoperability is a very important function in any factory or manufacturing unit. There must exist a modular framework for both hardware and software to connect and coordinate various end effector systems. The focus is not only on the software side, which is used for programming, diagnosing, and monitoring but also the interchangeability of hardware between the end effector and robot arm. There have been cases in the industry where a client has bought a robot arm and an end effector separately that were not fully compatible with each other, and the setup was a huge challenge from the onset.
