10. Bind the radio to the receiver and
turn on the robot. The servo will
immediately travel to where you have
left the throttle stick on the radio.
11. Move the throttle stick to the
down position, then mount the arm
on the servo so it's 1 cm from the
You have finished a one
pound clamp robot!
14. Now, mount the foam wheels using the
wheel hubs. Put a small dab of glue on the
hubs, then slide them into the foam wheels.
Finally, use the set screw on the hub and
screw it on to the driveshaft.
For the lifting robot, I invert the materials for a different approach. Although
the clamp robot is rigid so it can get a tight grip on its opponent, I build lifters
with a more flexible frame by using the Garolite as the rigid backbone and the
Lexan as the outer skin. The Lexan can bend and absorb impacts which makes
it excellent against axe, hammer, and spinning robots. For the lifter build, we
will construct the undercarriage in Garolite and the top plate in Lexan. It will
still need the titanium plates to prevent damage from cutting saws.
Print out the template (at the article link) for the lifting design. Cut the template
out and trace the parts onto their respective sheets. This time, you should have
three titanium plates, one Garolite base plate, and one large Lexan wedge. The last
piece is a rigid L made out of either carbon fiber or steel.
12. Once you are satisfied with the
position of your clamping arm, screw
the servo horn screw into the servo,
locking the servo in the desired
For the Garolite or Lexan, remember
you can use shears to cut the
template out. Use a 3/8” drill in the
corners to create a radius.
13. Screw down the bottom plate.
