Navigator2
Specification: Navigator2 is designed so that the momentary push button on the front right causes the robot to cut the left motor off so the only motor running is the right motor this causes Navigator2 to turn left because the only motor running is the right motor this is the same collision systen I used on Navigator1. Also I used a resistor to slow the fast dc motors down. Navigator2's power supply is two AA nimh (Nickel-Metal Hydride) batteries their 1.2v batteries I used these so my 3v 40ma solar cell could safely charge Navigator2's batteries and I used a led as a blocking diode to keep the battery's juice from leaking out when the solar cell charges the batteries also Navigator2 has a yellow on indicating led.

Problems: I had a couple problems like Navigator2 is a indoor robot and its solar cell does not work under non-intense indoor light but it does work around a window or a bright lamp. Another problem is that Navigator2 is some what back heavy so im going to try to find some method to fix this problem.

Parts: 1 Pc board which I used for Navigator2's body  it was purchased from radio shack for $2.69.
Two dc motors 1.5-3vdc these were purchased at radio shack for $1.49 each.
1 solar cell its size is 2.40 inches and I bought this from www.allelectronics.com for $3.50 plus shipping and handling $6.
Two AA battery holder it was purchased from radio shack for $1.49.
Total: $16.66 I had all the other parts already.

Time to build: I'm not sure because I worked on Navigator2 on and off.
