Compliant manipulator design method (COMAD) for the type synthesis of all serial and parallel multi-DoF compliant mechanisms, with example of a Sch?nflies motion generator

A. E. Huisjes et al.

Summary: This article introduces a compliant manipulator design method (COMAD) for the synthesis of serial and parallel multi-DoF compliant mechanisms. Unlike the current method (FACT), COMAD includes parallel solutions by combining legs in parallel to obtain complete compliant mechanism designs. The method was applied to a compliant Schonflies motion generator, resulting in new designs and successful experimental evaluation of the compliant mechanism's mobility.

Numerical determination of freedom spaces from any set of twists

Nigel C. Archer et al.

Summary: This article introduces a complete numerical algorithm to find the principal twists of all freedom spaces without constructing the constraint space. Additionally, principal geometry is proposed as a visual representation of all possible principal twists for a freedom space. Identifying freedom spaces has been a central problem in screw theory, and until now, there was no autonomous tool that can identify all freedom spaces. This tool can be integrated into solid modeling software to help design mechanisms using the FACT approach.

Mobility of overconstrained parallel mechanisms with reconfigurable end-effectors

Patrice Lambert et al.

Summary: This article presents a general method for calculating and representing the coupled mobility of multiple end-effectors. It provides insights on the mechanism in any configuration and can be used for obtaining numerical values of mobility in specific configurations. Two illustrative examples showcasing the method are presented.

A constraint-flow based method of synthesizing XY? compliant parallel mechanisms with decoupled motion and actuation characteristics

Haiyang Li et al.

Summary: This paper presents a constraint-flow based method for synthesizing XY theta compliant parallel mechanisms (CPMs) with decoupled motion and actuation characteristics. The method derives multiple constraint combinations for the compliant modules, resulting in a large number of possible synthesis schemes. Case studies demonstrate the effectiveness of the proposed method.

Type synthesis approach for the 2R1T compliant parallel mechanism with a suitable constrained branch

Yajie Zhou et al.

Summary: This paper proposes a new synthesis approach based on screw theory for the type synthesis of 2R1T compliant parallel mechanisms with a suitable constrained branch. The correctness and effectiveness of the approach are verified by analyzing the DOF of the synthesized mechanisms, and it is shown that this approach is also suitable for the type synthesis of compliant parallel mechanisms with 4, 5, and 6 DOF and a suitable constrained branch.

Design of Four-DoF Compliant Parallel Manipulators Considering Maximum Kinematic Decoupling for Fast Steering Mirrors

Guangbo Hao et al.

Summary: This paper focuses on the design of a four-degree-of-freedom compliant parallel manipulator to meet the requirements of FSM. Using a constraint map method, four required DoF are proposed and their kinematics are analytically estimated. A normalization-based compliance matrix is derived to validate the mobility of the system.

Synthesis method of two translational compliant mechanisms with redundant actuation

Shihua Li et al.

Summary: A new method for synthesizing 2T compliant redundant actuated parallel mechanisms was proposed, leading to the synthesis of new mechanisms and their subsequent analysis. The results confirmed the validity and effectiveness of the method, which can also be applied to compliant parallel mechanisms with different degrees of freedom.
