What changes

  • Bring the work closer650 → 380 mm from the base center: move targets 270 mm inward.
  • Raise and aim the robotMounting face 690 → 750 mm; turn the base 55°.
  • Lower the rolling stationWork point 980 → 880 mm; leave brush and kick at 980 mm.
  • Change pickup and travelReverse pickup/brush approach; turn with the output transfer; lift above the fixtures before returning around the front.
  • Use a custom tool and supports100 mm flange-to-grip assumption, slim fingers, raised pickup nest, 60 mm tray-rim opening and narrow fixture pedestals.

What this establishes

In the proposed layout, the modeled size-04 clamp can follow the path within the RS model’s joint limits. Aluminum versus steel does not change this geometric check.

Exact fingers, hoses, all clamp sizes and the finished fixtures still need a fit check. Force support can be added as Eli proposed.

Evidence and limits

Manufacturer RS URDF and visual meshes, using the existing Cell 1 WDG04 stamped-part mesh and fixed-hook forming path. This is a numerical fit study, not a live robot test.

Sampled inverse kinematics checks position and orientation. The clearance screen tests robot mesh vertices and custom-tool boxes against fixture envelopes; it is not a full swept-volume or self-collision test.

The 100 mm tool is a design assumption, not a verified bolt-on adapter. Use a fixed, correct-face pickup nest. The old upside-down pickup/flip fails at 24 of 40 tested poses; reshuffle or separately orient those blanks. Arbitrary tray pickups and sizes 01–16 are not qualified.

Manufacturer model

A43 / CELL 1 / TEAM PREPARATION

Two arms. One process to develop.

Feed and locate a blank → hold it through deburring, supported kicking and fixed-tool rolling → release to the WIP bin. Aluminum and steel are in scope; the current detailed fit study covers WDG04 only.

reBot B601-RS · ordered

Lower-cost development arm, approximately $2,000 before tax, plus the $99 matching power kit. Both have an Amazon delivery estimate of Wednesday October 21. Final invoice amounts are pending.

Start with MotorBridge / Python for connection and zero verification. Seeed’s current planning tutorial uses Ubuntu 24.04, ROS 2 Jazzy and MoveIt 2, with CAN communication. Prepare the model and simulate first. The purchased Protectli is the vision-PC candidate; controller-host performance and storage still need checking.

The proposed process tool uses the purchased SMC gripper and a custom adapter/fingers. The included stock gripper is useful for bring-up but is not the tool represented in this fit model.

FANUC LR Mate 200iD/7L · planned

Industrial-arm candidate, approximately $15,000 hardware budget. Eli plans to call the distributor Monday October 19. No order or delivery date is confirmed; final matched controller, pendant, cables and landed cost need agreement.

Proposed stack: HandlingTool / teach-pendant motion, with external PC vision through KAREL R632 + User Socket Messaging R648. Ask the distributor to confirm installed options and license rights. ROBOGUIDE / HandlingPRO and the KAREL compiler are a separate development-license question.

The FANUC animation is a concept layout, not a joint-limit or collision-validated simulation of the specific used robot.

Before the boxes arrive

Review the two layouts and the delivery list; prepare the RS software environment and virtual motion; review the camera, PLC and gripper handshakes; finish the custom jaw/adapter and fixture dimensions. After arrival, verify actual geometry and run slow dry cycles. Force assistance can come from actuators or backstops as needed.

Four guarding SKUs are ordered but backordered. Two additional SBC-18N silencer packs are still unpurchased. In-house fabrication, robot mounting/services and commissioning are separate from receiving purchased components.
