Honda Canada Mfg. Open House 2025
Assembling a model CR-V automatically
Project at a glance
- Helped create a UR10e cobot demo that assembled a 3D-printed Honda CR-V model.
- Designed a magnetic rack-and-pinion end effector with Arduino-controlled tooling.
- Achieved a 100% assembly success rate throughout the public demo day.

Why?
At Honda, we had access to cobots for demonstrations and public open houses. One demo used a robot arm to take small 3D-printed CR-V parts from a visitor’s hand and assemble them onto the model vehicle.
What?
I helped design the end effector. Magnets hold parts that contain matching inserts, and a rack-and-pinion mechanism pushes each part off during placement. We 3D-printed the tooling because the process was inexpensive and supported fast iteration.

Halfway through the build
How?
The UR controller communicates with an Arduino Nano through its available GPIO. It sends an analog output voltage, which the Arduino maps to a servo position. The Arduino provides the PWM update rate that the UR controller could not generate onboard.
Servo-control concept
ArUco tags allowed the robot to estimate each part’s pose before pickup. Their unique IDs distinguished the hood, tailgate, and front and rear doors. My teammates developed the robot controls, which achieved a 100% success rate during the public demonstration.
