How to Build a Robot - The BeetleBot v2 ( Revisited )

Step 16: The BeetleBot v2 ( Revisited ) - Mounting the power switch

Your robot should be able to move around and avoid obstacles.

To stop your robot, you need to remove the battery. This can get annoying and I recommend adding a simple switch.

Look at the pictures and you will understand. I have added heat shrink to make it look nice and hide my beautiful solder joint.

mine can run on one battery!

it also shocked me

[miteshchellapa]

and i have used NO switch !!!

[miteshchellapa]

i hav done everything as u have instructed but d problem is that when i connect d batteries the motor doesn't gets started and all the wires r connected properly can u give a solution for this ?

[r_carron]

i dont get this step...? in step 13 you soldered the wire from the back of the battery holder to the motor? ryte?
and you soldered the same wire to the switch and attached another wire to the motor to the switch.. i am lost now :(

wrong answer

[robomaniac]

you have 2 ways to build the robot.

with NO switch
or
with a switch



if you want NO switch, you simply don't check that step. Leave the wire from the back of the battery to the motor.


if you want a switch, you will need to cut the wire and attach a switch to it.

Hi ya wazzup yall

[hohohe]

Ref power switch @ 3rd connection (step 16). This does stop motors, but even in off (open) popsition, the lever switches still activate motors. Do I have something miswired.??

[Carnavislol]

will a battery holder that has a switch on it work?

[fundash]

 oh no!

i installed a switch and had mine working fine, until for some reason, the motors wont reverse...the just stop

also, when the on/off switch is off and i press a motor switch, the motors don't do anything! :(

Please reply!!!

[elmvet]

My motors don't reverse when antennas contact surface.  wired as per v1 but added a switch.  your wiring diagram could be clearer.

hey Garrett, im 15 years old and iv have always wanted to know how to make a simple yet fun robot. The beetle bot is so cool because you dont need a CB (circuit board) or a programmer to make it. my one question is do i HAVE to use 3V motors or can i use a smaller one and just make the robot smaller? thanks Garrett :)

[raykholo]

well that all depends exactly on what u said if ur gonna make the robot smaller then it might be possible to use smaller motors However, that would require u to totally remake this design and that kinda defeats it if so i would just apply this circuit to a different robot idea otherwise, it is possible to use smaller motors on this robot, but then i would suggest gearing it for more torque and thus the robot would move slower...

[smilespoon]

should v solder the 3rd connection to the positiv or negativ terminal of the battery holder

[Migacz]

negative... Mine works!!!!!!!! PS solder it to the spring- it goes faster!!!!!
