- Page 2 STEP 1: Cross Channels Using eight of the 12mm long screws, fasten one Quad Block Pattern Mount per side of a 10 Hole U-Channel as shown. Repeat this process on the other 10 Hole U-Channel. If at any point you run out of the recommended screw lengths use the next size up or down depending on the situation.

STEP 3: Motor Mounting Using eight of the 12mm long screws, attach two motors to the 10 Hole U-Channels as shown. STEP 4: Back Wheel Assemblies Using four of the 12mm long screws mount the Sonic Hub to the Rhino Wheel. Ensure the screws go through the deeper side of the wheel. - Page 4 STEP 5: Back Wheel Collars Tighten a 6mm Set Screw Collar flush with the end of an 80mm Long Shaft on the flat side of the shaft. Then slide a shim, a bearing, and another shim as shown. Repeat this step for a total of two shafts. If you run out of 80mm Long Shafts (shorter size) you can use a 100mm Long Shaft (longer size) instead, just be mindful of where the extra length sticks out.
- Page 5 STEP 7: Attaching Back Wheels Put a bearing through the 13 Hole U-Channel followed by a shim to keep the hub from rubbing against the bearing. Now slide the wheel assembly on and tighten the Sonic Hub. Repeat this process for both sides. You need to use a ball-end hex key to tighten the Sonic Hubs.
- Page 6 STEP 9: Front Wheel Assemblies Using four 30mm long screws attach two omni wheels together with a 4mm Pattern Spacer in between onto a Sonic Hub as shown. Ensure the rollers spin easily when assembled, otherwise take it apart and rotate one of the omni wheels slightly before putting it back together.
- Page 7 Repeat for both sides of the robot. STEP 12: Electronics Box Attachment Mount the electronics box (found in white goBILDA box with controller) as shown. You may use 12mm screws and nuts or thread directly into the plastic mounting points from below.
- Page 8 STEP 13: Motor Wiring Plug the motor wires into the corresponding connectors (look at color coding) coming out of the electronics box. The red wires should connect to red wires, and the black wires connect to black wires. Feel free to wire manage as you please using the included zip ties, a recommendation is shown in the image below.

Page 9: Step 15: Connecting The Controller
STEP 15: Connecting the Controller 1. Start with the controller and electronics box powered off. 2. It is now time to turn the electronics box on by flicking the switch, the box should light up when on. The receiver’s orange LED will blink slowly. 3. - Page 10 STEP 17: Tuning Driving You might notice that when you let go of the right gimbal which is used for driving one or both of the wheels continue to spin. If this is the case try adjusting the Trim Switches labeled “G” and “H”. When you hear a long beep while adjusting it means you’ve hit the max it can be adjusted in that direction.
