Mechanical Assembly
All hardware should be installed with Loctite unless a locknut is used. As with any assembly, put all
hardware into place before torqueing anything down.
This is how we typically assemble the Robot. If you do not have basic hand tools and some mechanical
ability, we suggest you let us do the assembly.
Drive Installation
Bolt on the front axles with the supplied #10-32 Bolts and Nuts. Mount the axle plates to the front of the
chassis and insert the bolts from the outside in. Once on use the Nylock nuts to fasten the plate to the
chassis and be sure to tighten them.

Now to mount the Drive motors. Install the drive motors. Use Loctite and the M5 machine screws and
washers provided with the kit. You can leave the bolts a little loose until you get the chains installed and
tensioned.

Mount the tension blocks with the #6 hardware. Get all the screws started but can leave them loose until you
install and tension the treads.
Slide the rear axle into the tension blocks. Make sure to slide it in so that the middle key slot will line up with the
flipper arm motor.

Use a lock collar on each side of the blocks to hold the bearings from sliding out. Do not tighten these yet.
Put the sprockets on the motor shafts. The #25 sprockets are used for the drive wheels. The #35 sprocket is used
for the flipper arm. Put Loctite on the setscrews but do not tighten them down all the way as you will need to
adjust them later in the assembly.

Install the back-handle strap. The #10 screws serve two purposes, to tension the treads and also to hold the
strap. Get the bolts started in the back of the tension blocks and leave them loose until the tread is installed.

Wheel Assembly
Assemble the wheels. You will have two drive wheels with the sprockets mounted, and two idler
wheels with no outside teeth or sprocket.
Idler wheel assembly. Sandwich the rubber between the two plastic sides. Bolt them together and then
press in the center sleeve bearing.
Assemble the drive wheels. These use the sprockets and the rubber with the teeth formed into them.
Final assembled wheel is on the left.

Slide the wheel with the sprocket on the front axle. Use a thrust bearing as a spacer. Put another thrust
bearing on and then a lock collar to hold everything in place.
Wrap the #25 chain around the sprockets and cut the chain to the nearest link. Make sure the motor is
slid forward in the slot so you can have plenty of adjustment after it is connected.
Install the master-link in the chain as shown.

It is very important for everything to be aligned properly. The motor sprocket can be moved in or out to
get the chain aligned. The wheel and tread guide should also be aligned.
Repeat the previous steps for both sides of the robot.

Line the flipper arm sprocket up with the motor sprocket. Now is when you should also measure from
then end of the shaft to the robot chassis. Adjust the shaft to get each end equal distances on each side.

Insert the 1/4-20 setscrews into the flipper arm on both sides (top and bottom).
The opposite side does not have a sprocket, so the spacing will be different. Use a thrust bearing and
two lock collars for the spacing.

Slide the remaining wheel on the shaft, then another lock collar. Install the remaining key and then
flipper arm onto the shaft. Once everything is in place, you may want to adjust the shaft from side to
side to make spacing equal, then tighten down all the setscrews on the shaft, including the lock collars
on the inside of the robot chassis.

You can now wrap the treads around the wheels. Make sure the tension blocks are slid all the way
forward and roll the tracks on each side.
The treads are the first thing you have to tension. Make sure the flipper motor bolts are loose, tension
the treads and tighten down the #6 bolts that hold the tension blocks. Now tension the flipper arm
chain. We find it easiest to slide the motor from the inside of the chassis and tighten the motor bolts
down.
Tension bolts. With everything loose, tighten these 4 screws and they will put tension on the treads. Be
sure to tighten each one evenly. We measure each side of the robot, from front axle to back axle and
get them the same distance center to center. This makes sure the rear axle is parallel with the front
axles.
