A basically simple Beetle Robot
The Beetle Robot is a simple diy robot to impress youngsters or your non-technical friends. Its construction and operation are simple enough for just about anyone to understand.
The only components necessary are:
- 2x - small 1.5 Volts motors
- 2x - small paperclips
- 2x - big paperclips
- 2x - batteries AAA or AA
- 1x - battery holder AAA or AA
- 1x - 2 cm of heat shrink
- 1x - wooden pearl (for the caster)
- 1x - meter of electric wire
- 2x - Sub-mini lever SPDT switches
The beetle’s operation is also fairly simple. If one of the SPDT switches is tripped, the polarity going to one of the motors is reversed. This causes the beetle to back away in the opposite direction.
The instructions are sketchy to say the least. ” Take the battery holder and make a connection to the connection.” Fortunately, the pictures are easy to follow.
