2015 FIRST World Championship Creo Modeling Challenge #4 - Robot Gripper Mechanism

Creo Parametric CAD Modeling Challenge

For this fourth Creo Parametric CAD modeling challenge, you will be creating a full assembly of the robot gripper shown below. You need to know basic Creo Parametric assembly constraints, Kinematic constraints and assembly structure to complete the design. It is a complex model to create, but you will need to master Creo Parametric Pin constraints to make it work correctly.

 

HINTS

  • Assemble the gripper plate first and make sure it is grounded
  • Add all the hardware at the end
  • Create one side first to make sure it works as desired
  • After placing the gear, add a second constraint (Slot) using the curve (blanked on layer) to control the range of motion
  • Use a Parallel constraint for the gripper_tips to make sure it does not ground (fix) the whole model
  • Watch a video of the mechanism motion

Extra Credit

  1. Create a 1:1 gear connection to synchronize the motion
  2. Add a motor to one of the gears to simulate the full motion
  3. Create a rendered video of the full simulation
