I know I am going to be asked about battery life no end of times, I just wondered if there was any other power source for limited motion. Like some kind of umbilicus that can bypass the battery, but still use the body with shoulder servos - would be hand for schools working with scripting.
As @jstarne has mentioned, a wall adapter is what your looking for. You will want to find one (correct voltage of course) that will deliver about 15 amps upwards for powering and controlling servos.
- Output: 7.4 volts
- Amperage: 20 Amps
*Note: A PC Power Supply will not work because it is only 5 volts. You need minimum 7.4 volts and 20 amps.
This is the closest I have found: http://www.ebay.com/itm/0-30-Volt-0-20-Amp-Adjustable-DC-Power-Supply-CSI3020X-/381030705865?pt=LH_DefaultDomain_0&hash=item58b7332ac9
Or this is a little cheaper: http://www.ebay.com/itm/TekPower-HY3020-SWITCHING-DC-POWER-SUPPLY-VARIABLE-0-30-VOLTS-0-20-AMPS/271786203570?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20131003132420%26meid%3D72e0433d9a38418cb3400e75220df2f4%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D381030705865&rt=nc
On a side note, can you give Jake a nudge to get in touch with Rob and Matt at the Tablet Academy about becoming a reseller, we have had a ton of interest from people at the show.
Thanks
