A mobile charging station, made by Instructables under the nickname awood22, is convenient to use in a robotic mug. It is a double-sided roller trolley, on each side of which there is a sachet with pockets for storing batteries for robots. Also at the station there are extension cords for powering chargers that allow you to charge batteries directly in your pockets.
To make the base, the master takes a thin wooden sheet and three bars with a section of 50x100 mm and a length of 900 mm. Leaves two bars as is, the third shortens to 565 mm. Positions as shown in the following photos. Tightens with screws. Drills holes at a distance of 540 mm from each other.
The base is ready, it's time for the charging station to go up. The master takes two more of the same bars, does not shorten any of them, drills the holes in the base to allow the screws to fasten them, and then fastens the bars with these screws as shown below:
Then the master takes two wooden sheets, makes a recess in each of them with dimensions of 159x76 mm, and fastens them with self-tapping screws to the vertical bars on each side, as shown in the following photos. To these parts of the trolley he will then attach a sachet with pockets for batteries.
The master makes two side panels, and then on each of them drills holes at a distance of 530 mm from each other, as shown below:
But the height of the side panels is too small, because they are cut from waste:
Therefore, the master from the same waste makes additional parts that increase the height to the necessary:
It looks like the result of such an increase on the assembled trolley is visible on the KDPV so that you do not have to scroll up and then down again, I will show again:
The master cuts out two thin wooden sheets with dimensions of 750x229 mm, drills holes in them at a distance of 686 mm from each other, then screws them with screws at the bottom on each side parallel to the sheets for attaching the sachets and, accordingly, perpendicular to the side panels.These sheets make it possible to store at the bottom of the charging station certain items that will not fall on the floor.
The master paints the finished trolley with paint from a spray can:
He takes the finished sachet with pockets, cuts it in half, fastens the halves on each side to the wooden sheets intended for this. Two homemade sachets will do.
Places handles on the side panels to move the cart. In this case, they are 3D-printed, since there is still a 3D printer in the robotics club, why should he stand idle? But fit, for example, door handles.
The master parallelizes (using a conventional extension cord) extension cords with built-in interference filters, drills a hole for the cord coming into a conventional extension cord, and displays it outside:
Adds videos, as shown in the following photos, which makes the charging station mobile, which was originally required of it. The pins of the rollers must be glued to the mounts (also 3D-printed) so that they do not fall out.
Further, the master indicates errors that he would not repeat if he had to make such a charging station again:
1. Instead of thin wooden sheets, he would use plywood.
2. 3D-printed roller holders were not strong enough, so he would have used ready-made ones.
3. And most importantly - he would first measure the width of the door of the bus, on which the circle go to field classes, and reduce the station so that you can take it with you.
But history does not tolerate the subjunctive mood of all these “woulds,” and the leaders of other robotics circles can avoid corresponding errors when repeating this design. In general, the thing turned out to be very useful: chargers and batteries are no longer scattered throughout the circle of the circle, it does not take time to find them, which can be spent on the educational process.
